11 Figure: Uniform Gentle slope Steep Slope When the degree or angle of slope of a feature is high and the contours are closely spaced, they indicate steep slope. Cliff 15. A rise of 50 feet over a run of 100 feet yields a 26.6° slope angle. In geology and geomorphology, cuesta refers specifically to Butte 7. The contours representing this type of slope are far apart. An accurate survey of … On the whole, the Bangar region is characterised by patches of saline efflorescence which is the result of the mechanical composition of alluvium, gentle slope of the land and the capillary action during hotdry season. The damage However some slopes bear both characteristics, a concave slope is gentle at the lower ground and gets steeper at the higher ground. The topographical factor Although slope has a powerful influence on erosion, the presence of erosion and heavy runoff on gentle slopes (2% in the Sahel or on European uplands) indicates that this phenomenon can occur without any need for a steep slope: … as they grow long loops the curve is cutoff and formed into Oxbow lakes. II. An alluvial fan at the mouth of Copper Canyon, Death Valley, California Slopes can either be gentle or steep. Internal strength in these systems is derived from the effects of the solidification and crystallization of magma or the lithification of once loose particles. 11. 1. Slope Calculation from Contour Lines in a Topographic Map Slope is the measure of steepness or the degree of inclination of a feature relative to the horizontal plane. Rock slopes generally have the greatest internal strength. Altitude : Height of an object in the atmosphere above sea level. Answer: The region in the north shown in dark green is the North Indian Plain. The easiest way to determine the percent slope of an area is to measure the change in height (elevation over a measured distance), then calculate the percentage of slope. Cliffs and slopes that drop sharply in elevation are steep slopes, whereas topography that is less steep is referred to as being gentle, as in a gentle slope. 12 How are the gentle and steep slopes shown on a map? The topographical factor Although slope has a powerful influence on erosion, the presence of erosion and heavy runoff on gentle slopes (2% in the Sahel or on European uplands) indicates that this phenomenon can occur without any need for a steep slope: … When contour lines are closer to each other, then slope is called steep slope. Saddle (pass) and col A Col is the land between two peaks of a mountain or in the mountain ranges. SLOPE/GRADIENT Gentle slopes: when contour lines are far apart. Subject Module #2 Unit #2 Lesson #3 SOIL CREEPSOIL CREEP BEGINBEGIN 2. In Figure 15.2 a block of rock situated on a rock slope is being pulled toward Earth’s centre (vertically down) by gravity. This type of slope is known as Normal slope. Usually, a shelf is less than 650 ft (200 m) deep; in ANTARCTICA the continental shelf averages 1,650 ft (500 m). Gradient or slope: When the gravitational force acting on a slope exceeds its resisting force, slope failure (mass wasting) occurs. Many constant slopes only have a very thin cover The slope is said to be steep when the land surface is rising/falling sharply and said to be gentle when the rising/falling of the land surface is mild. OBJECTIVESOBJECTIVES What is … On two sheets of paper, one for steep slope and one for the gentle slope: a square of 10 cm by 10 cm was drawn and divided into 100 squares, each measuring 1 cm x 1 cm. This convex side is charac terized by gentle slope and is called the side of slip-off slope (fig. in the East direction of Lucknow the Capital of Uttar Pradesh. We describe steepness of a slope … It has a GENTLE SLOPE … Topographical maps show varying degrees of slopes. Use the following formula to determine slope: Rise ÷ Run = Slope % 11 How will you identify gentle and steep slope? On a map the contour lines will be spaced closer together with a decline in height above sea-level. Geography Class 10 Chapter 3 Physiography Steep slope: when contour lines are close together Click on the link to watch a video illustrating the difference between gentle slopes and steep slopes Steel slope vs Alp: A gentle slope above the steep sides of a glaciated valley, often used for summer grazing. The word is from Spanish: "flank or slope of a hill; hill, mount, sloping ground". 5.1 Find a physical map Alp: A gentle slope above the steep sides of a glaciated valley, often used for summer grazing. gentle slope from head to toe and they appear as high cones with steep slope in arid and semi-arid climates. Sidewind moves the sand grains on the sides forward creating the two edges which … Subject Module #2 Unit #2 Lesson #3 SOIL CREEPSOIL CREEP BEGINBEGIN 2. black and white lines on gray map colour) would give a shading effect as if the relief were illuminated. CXC requires Geography students to be able to calculate the gradient of a slope and express it as a ratio. | Meaning, pronunciation, translations and examples A slope is the inclination of the land's surface.Steep slopes are defined as areas that exceed a certain percent slope.Steep slopes are often associated with other environmental features such as rock outcrops, shallow soils, bedrock fractures, and groundwater seeps. As adjectives the difference between steep and gentle is that steep is of a near-vertical gradient; of a slope, surface, curve, etc that proceeds upward at an angle near vertical while gentle is tender and amiable; of a considerate or kindly disposition. Concane bank is eroded and also it is called cutoff bank convex side is long gentle slope. Convex Slope: The slope is very steep at the foot and it goes on becoming gentle towards the top. as they grow long loops the curve is cutoff and formed into Oxbow lakes. The gentle slope means a large expanse of sand at low tide, but also means that the incoming tide advances rapidly up the beach with the potential to trap unwary beach users. Geography M2 Soil Creep 1. Describe three important features of the Due to their gentle slope and the fact that the water speed is slow in the shallows of the point bar they are popular rest stops for boaters and rafters. Saddle/ col 16. The lateral erosion on the outside bend causes undercutting of the bank to form a river cliff. However some slopes bear both characteristics, a concave slope is gentle at the lower ground and gets steeper at the higher ground. The damage Geography, SS 2, Week 2 Topic: Contour Representation of Landforms The following are some common landforms or relief features that can be represented on map by using contour lines. ADVERTISEMENTS: The concept of geographical cycle of erosion recognises the possibility of obliteration of relief, or planation, during the life history of a landscape, by process of erosion, occurring in a sequence of orderly changes, finally reducing the landscape relief to a minimum. It can refer to an entire slope or part of one. The less separation between contour lines means a steeper slope and vice versa. Closely spaced contours represent a steep slope. Thick and short hachures represent steeper slopes while thin and long hachures represent gentle slopes. •b) The free face A steep slope or part of a slope formed of bare rock. What does Steep slope mean? Right: a gentle slope. Meaning of Steep slope. Driving down a highway you may see a . 9 What is a gentle slope in geography? Figure : Uniform steep slope 12 Figure : Uniform steep slope 12 Concave Slope A slope with a gentle gradient in the lower parts of a relief feature and steep in its upper parts is called the concave slope. These gentle slopes are seen in this area only along the river. That's because the slope measures how steep the line is, and a flat line is not steep at all and therefore has no slope. Spur 13. Escarpment (1)scarp slope– steep slope (2) dip slope- gentle slope (3) plain- flatland Knoll and undulating slope/ plain - An isolated small and low round hill separated from nearby highlands Undulating slope Undulating plain Steep Slope When the degree or angle of slope of a feature is high and Valley 12. In general usage, a cuesta is a hill or ridge with a gentle slope (backslope) on one side, and a steep slope (frontslope) on the other. are used interchangably with slope. Types of Slopes in Geography The rate of rise or fall of a piece of ground feature is understood as its slope. contours (steep slope, gentle slope, hill, valley, ridge / water divide, escarpment), triangulated height, spot height, bench mark, relative height/ depth. Concave Slope: The slope is very gentle at the foot and it goes on getting steeper and steeper towards the top. Gentle slope because when the contour lines are close to each other then it is steep slope. Mesa 8. The space between contour lines reflects the slope. Geography M2 Soil Creep 1. Barchans are convex facing the wind, with Gentle gradient 3. Gradient, grade, incline and pitch are used interchangably with slope. Convex slope 4. A slip-off slope is a depositional landform that occurs on the inside convex bank of a meandering river. Gentle slopes and V-shaped valleys are covered with thin layers of sediment deposited by wind and water. For decades, slope profiles served as the primary technique for portraying and communicating theories for slope development, although few geologists endeavored to objectively measure slope angles in the field until the 1950s (). Slope Classes * Simple topography Single slopes (regular surface) 4 depressional to level 6 very gently sloping C gently sloping D moderately sloping E strongly sloping F steeply sloping G very steeply sloping H extremely sloping For decades, slope profiles served as the primary technique for portraying and communicating theories for slope development, although few geologists endeavored to objectively measure slope angles in the field until the 1950s (). They do not represent exact elevations but are mainly used to give a good impression of the shape and slope of the ground. In which direction is the slope of the region in the north shown in dark green. Characteristics of soil erosion change along a long slope in the gentle hilly areas in black soil region in Northeast China are discussed. The shape of meander is usually semi-circular but sometimes it is also circular. Waterfall 17. Gentle Materials, underlying the gentle slopes, are dacite gravels and sand, and differ from the bed rocks, tuffaceous sand and tuff breccia. gentle definition: 1. calm, kind, or soft: 2. not violent, severe, or strong: 3. not steep or sudden: . Contours are imaginary lines connecting places having same elevation above mean At a stream junction, contour The slope is always perpendicular to contour lines. A slope's shape is governed by its internal structure and external processes, such as slope wash, creep and other mechanisms of sediment transport. Material deposited while in transit down the slope is termed colluvium --an unsorted mixture of rock and sediment derived from the slope face. On the whole, the Bangar region is characterised by patches of saline efflorescence which is the result of the mechanical composition of alluvium, gentle slope of the land and the capillary action during hotdry season. When contour lines are further apart from each other, then slope is gentle slope. The continental shelves are the regions of the oceans best known and the most exploited commercially. The angle of the slope was measured with the ranging rods and clinometers 2. A steep slope refers to a sharp incline; a gentle slope to a slight incline. Gentle gradient A Uniform slope is a slope with evenly spaced contours, it can be for hills of any gradient, weather it is steep or gradual, but they have to be evenly spaced. 3. Convex slope 4. Concave slope 5. Conical hill 6. Butte 7. Mesa (table mountain) 8. Dip slope and 9. Scarp slope 10. Homoclinal ridge 11. Valley and 12. Spur 13. 13 Which indicates the slope of 14 Concave slope 5. Gentle slope definition: A slope is the side of a mountain, hill , or valley . Dip slope 9. Slope stability is ultimately determined by two factors: the angle of the slope and the strength of the materials on it. The shelf has a gentle slope and is the shallowest portion of the ocean. Altitude : Height of an object in the atmosphere above sea level. Saddle (pass) and col A Col is the land between two peaks of a mountain or in the mountain ranges. This slope can be determined from the map by studying the contour lines—the closer the contour lines, the steeper the slope; the farther apart the contour lines, the gentler the slope. 1. 1 GEOGRAPHY GRADE 11 WEEK 5 - SLOPES You must use these Resources: • • LEARNER TASK: Use the information on Page 3 and your textbook to complete the following task in your workbook. Gradient is calculated using this formula: OR A side on which hard layers dip and has a gentle slope. A slope's shape is governed by its internal structure and external processes, such as slope wash, creep and other mechanisms of sediment transport. The spacing between successive contours at the lower level is more than at the higher level. It can refer to an entire slope or part of one. The slopes above 45 is depicted completely in black colour. Further, shape of alluvial fan depends on the climate such as in humid areas they show normally low cones with gentle slope from head to toe while in arid and semi-arid climate, they appear as high cones with steep slopes. One of the commonest types of dunes, it occurs in sandy deserts all over the world. The hachures are traditionally monocolour, usually black, gray or brown. See Synonyms Figure 7.10.2 A rise of 100 feet over a run of 100 feet yields a 45° slope angle. The slope of a line is usually represented by the letter m. (x 1, y 1) represents the first point whereas (x 2, y 2) represents the second point. Totally flat ground has no contour lines. Antarctic Circle : Imaginary line that encircles the South Pole at latitude 66 o 32'S. The slopes can be classified into gentle slope, steep slope, concave slope Antarctic Circle : Imaginary line that encircles the South Pole at latitude 66 o 32'S. New questions in Geography mean Radius of the earth is_____. 5.3 Mass Wasting Mass wasting, which is synonymous with slope failure” is the failure and downslope movement of rock or unconsolidated materials in response to gravity.The term landslide is almost synonymous with mass wasting, but not entirely because some people reserve “landslide” for relatively rapid slope failures, while others do not. The slope of a horizontal line is zero. Conical hill 6. Map interpretation is the interpretation of the symbols and signs used on map into ordinary language by indicating the features they represent and draw logical conclusions from the information as represented by the symbols. 5.1 Find a physical map Material deposited while in transit down the slope is termed colluvium --an unsorted mixture of rock and sediment derived from the slope face. The wind blows sand over the leeward side creating a smooth gentle windward slope. Alluvial fans in humid areas show normally low cones with a gentle slope from head to toe and they appear as high cones with a steep slope in arid and semi-arid climates. OBJECTIVESOBJECTIVES What is … Valleys: are lowland between two highlands. 11. Gentle: Contour lines Homoclinal ridge 11. Slope (in degrees) Gradient Steepness Comment 35-45 1 in 1 Very steep Hands need to scramble up 20-35 1 in 2 (50%) Steep Roads or paths need to zigzag 12-20 1 in 3 (33%) Fairly steep Problem for heavy vehicles 6-12 1 in 10 Point bars are formed as the secondary flow of the stream sweeps and rolls sand, gravel and small stones laterally across the floor of the stream and up the shallow sloping floor of the point bar. It slopes towards the east. 3 All of this should make good qualitative sense to you, because it’s part of the human experience: we are pulled down a steep slope more than down a gentle slope. Structural Benches: The step-like flat surfaces on either side of the present lowest valley floors are … A slope which becomes progressively steeper downhill. Gentle sloop and steep slope both are the types of slope. Considering this, what is the difference between a steep slope and a gentle slope? 5. are lowland between two highlands. Gentle Slope When the degree or angle of slope of a feature is very low, the slope will be gentle. There is less water on the inside bend of a meander so friction causes the water to slow down, lose energy and deposit the material the river is carrying, creating a gentle slope. The gentle slope lands occupy a major part of this region. 5. Learn more. 1 GEOGRAPHY GRADE 11 WEEK 5 - SLOPES You must use these Resources: • • LEARNER TASK: Use the information on Page 3 and your textbook to complete the following task in your workbook. Definition of Steep slope in the Definitions.net dictionary. Gradient is a measure of how steep or gentle a slope is. Flat areas are never strictly horizontal; there are gentle slopes in a seemingly flat area, but they are often hardly noticeable to the naked eye. The slope / gradient is gentle (1 x 1) (1) 2.3 Refer to the line drawn from spot height 1461 in block C1 to the ruin at O in block C2 on the topographic map. ADVERTISEMENTS: The earth scientists have attempted to interpret geomorphological processes or … Apr 19, 2013 - Learn about and revise different types of volcanoes and their characteristics and effects with GCSE Bitesize Geography (AQA). Poort 14. LOCATION and BOUNDARIES The district Barabanki is situated about 29 Kms. Hachures usually vary in thickness and length. There square measure 6 sorts of slopes: Gentle Steep Concave Convex Tectonic Depositional #1. A gradient is usually used to measure how steep or how gentle the slope is. Using two complementary colours for the hachures on a neutral background colour (e.g. (c) Interpretation of colour tintsand conventional symbols used … The lines are drawn thicker to represent steeper slopes and thinner for gentle slope. To diverge from the vertical or horizontal; incline: a roof that slopes. A slope mass movement is defined as the movement of material down a slope (Heinson, 2015). Barchan, crescent-shaped sand dune produced by the action of wind predominately from one direction. Gentle Slope: When the contours are situated at large distance in a region of a map and variation in height because of distance is less than 1/10 to 6°. These examples are from corpora and from sources on the web. Figure 7.5 : A satellite view of part of Krishna river delta, Andhra Pradesh Figure 7.6 : Natural levee and point bars Mass wasting is very common and severe in areas with steep lands as compared to flat or A simplified slope model based on segments was used to analyze the runoff data and soil erosion data observed between 2003 and 2004 over 10 field plots with different slope length in Heshan Farm, Heilongjiang Province. (b) The Deccan Plateau has a gentle slope towards the east, thus the rivers drain towards the east. They are shown in orange colors. 18.10). When there are evenly spaced contours, the slope is uniform. They are shown in orange colors. Fortunately, this is quite simple. Since degree of slope is equal to the tangent of the fraction rise/run, it can be calculated as the arctangent of rise/run. River channel 18. Map reading is the process of identifying features on a map by using symbols and signs or names.This technical work requires certain skills that any map reader must possess. A very gentle slope or a flat area, like the top of a hill, is usually left blank. Concane bank is eroded and also it is called cutoff bank convex side is long gentle slope. Two rivers draining into the Arabian Sea are the Narmada and the Tapi. Gentle slopes and V-shaped valleys are covered with thin layers of sediment deposited by wind and water. Its borders, a hundred yards from the ship in either direction, were gentle slopes of black lava. Scarp slope 10. Slopes represent the rising or falling of the land surface. Information and translations of Steep slope in the most comprehensive dictionary definitions resource on the web. Widely spaced contours represent a gentle slope. The term can refer to two different features: one in a freely meandering river with a floodplain and the other in an entrenched river. Dip Slope Scarp Slope A natural/gradual slope on the surface of the ground which is parallel to the dip of the underlying strata. Question 90. 10 What are the types of slopes in geography? Wind eddies act on the leeward slope, making it to be steep and concave. D. puntazzo, D. sargus and D. vulgaris were observed in sites presenting a gentle slope with coarse sand, gravel, pebbles or boulders. The biggest one, Fukue, was born from volcanic activity and has fairly gentle slopes. The majority of the gentle slopes face south south-west, providing perfect climatic conditions. Thus landslides, rock-slides, mudslides and rock-falls are all types of slope mass movement. The length of a meander belt can be found out on the basis of the channel width because meander belt is usually about 15 to 18 times the width of bankfull channel. Judging from its extent, materials and other conditions, these gentle slopes probably were made by earthflow. Gentle Slope A slope with contour lines spread far apart from each other. This even spacing is maintained in both up and down slope •Steep Slope A slope represented with contour lines close to each other on a topographical map. •Convex Slope A slope which becomes progressively steeper downhill. It can refer to an entire slope or part of one. ing , slopes v. intr. •c) The constant slope is a slope with a uniform angle that did not alter as the slope developed through time. The steep, forested slopes in Figure 1.1 contrast with the gentler slope of the river’s path as it flows between them. The speed at which a bushwalking group can move is affected by the slope of the ground or terrain features.
