Soil conservation includes all such measures which protect the soil from erosion and restore its fertility. These measures are of two types-(a) small measures to check soil erosion at local or even individual level‚ and (b) large measures at government level involving larger area and heavy investment. (a) Small Measures-These include afforestation‚ regularised land strip cultivation or contour farming or terrace farming in hilly areas‚ use of stubble mulch system‚ increasing cohesiveness of the

of a river is the speed at which water flows along it. Lateral erosion- Lateral erosion in a river is the wearing away of the sides of the river which makes the channel deeper because rocks being carried in the river will erode the sides of a river. Bed load - Bed load is complementary to suspended load and wash load. Bed load moves by rolling‚ sliding‚ and saltating. Vertical erosion- Vertical erosion is the downward erosion which deepens the river channel. Hypothesis Whedn going

CCEA GCSE‚ K. Clarke Pg.2) Rivers as agents of change in the landscape (TED depending on available energy) “Rivers change the landscape through which they flow. They alter it by erosion‚ transportation and depostition” (http://www.bbc.co.uk/schools/riversandcoasts/rivers/change_river/pg_06.shtml 18.06.2013) River erosion is the wearing away of the land as the water flows past the bed and banks. River deposition happens whenever the velocity of the river drops; meaning that there isn’t enough energy

AS geography revision Start early…. There is a lot to learn. Use this as your starting point. There is more help available on the geography revision pages of Moodle and also on AQA’s website‚ where you will find past papers‚ mark schemes and also examples of student answers (exemplars). You can buy a CGP revision guide if you would like to (£5 from college) but also on Amazon and from WHSmith. The bits that the CGP revision guide doesn’t have in it for AS Geography….

To what extent do you agree that river landforms can be classified as either erosional or depositional? Many different landforms are made by either deposition or erosion and there are some cases where they can be classified as both. Erosional landforms are caused by erosion which is the breaking down and transportation of particles from one area to another. Depositional landforms are made when particles are deposited somewhere else. In my opinion I think that river landforms can be classified

Therefore‚ alternatives to these hard structures are strongly encouraged and actively sought by the NPS.” Breakwaters -“Dunes not directly disturbed‚ increases area of dry upper beach‚ may allow new

effectively working ........ • The amount of soil erosion will decrease with distance from the main footpath • Plant height and diversity will be greater the further away from the main footpath • The management strategies are effective in managing visitor numbers and tourist’s impacts . 12/7/14 Alexander Jay-J Achebe 4 Hypothesis 1 I have decided to measure soil erosion(near the footpath) as my first hypothesis. I have chosen to investigate soil erosion because one of the government’s

and cycled by water or wind is known as erosion. Soil erosion can occur anytime soil is bare or exposed and naturally removed by wind or water. This form of soil degradation is a natural process but it further elevated by human activity. Human disturbances of the soil allow for this process to happen more rapidly under natural conditions. According to the University of Michigan‚ whose geologist conducted a study‚ human actions produce 10 times more erosion and move 10 times as many sediments of soil

eventually flow in the same pattern and ultimately‚ will end up in the same stream or river. Why do river shapes vary in wet and dry climates? River shapes change in various climates due to different erosion patterns. In dry‚ arid regions‚ the river valleys are often deep and/or steep. This is due to little erosion on the valley walls as the flowing water will erode the floor continuously‚ digging the valley deeper but not wider. Eventually‚ a deep canyon or gorge will take shape. In areas of high precipitation
