What Causes Erosion? (Geography)?

Question

I need to find out about erosion and what it is for a newspaper article. Snap Snap!

Answer 1

erosion happens when trees are cut in an area. water breaks rocks and minerals causing a new landscape.

Answer 2

Erosion is caused by water breaking down rocks and dirt to make a new landscape.

Answer 3

lol. what newspaper "poor research garbage daily"? :P

erosion depends upon surface coverage, what the ground is composed of and the climate. eg an area with a high amount of rain fall (or just rivers) will have a high amount of eroision

Answer 4

i recently done higher geography and there are 3 main types of erosion

1st which is glacial erosion which occured years and years ago. when a great big iceberg moves down a V-shaped valley and by abrasion flattens and widens the valley floor like sand paper. corrosion pulls rocks out of walls widening the valley further.

2nd is chemical erosion created in upland limestone landscapes. as rain is a weak carbonic acid it dissolves the limestone. this process is called chemical weathering. it removes it in solution called calcium carbonate and is moved into a cavern creating pointy rock structures called stalagmites (up) and stalagtites(down).

3rd is coastal erosion which is when the waves are pounding at the headland. once the water starts to find a fault in the the headland it will bash at it until it becomes a crack then into a sea cave. eventually it will erode all the way though creating an arch. this arch will then collapse leaving a stack.

an additional form of ersion is the human factors such as deforestation which is the cutting down of trees and also urbanisation which is expanding cities

Answer 5

time and life that disapates.,,.,. the earth does that just like a human

Answer 6

Rain (washes soil away)

Wind (blows soil away)

Ice (water goes into cracks in rocks and expands when it freezes, fracturing the rock)

Deforestation (trees help hold the soil together)

Poor farming methods (removing too much natural vegetation or growing unsuitable crops for the climate means topsoil gets washed/blown away)

Too many hard surfaces (like roads, houses, paths etc - the rain can't soak in to the ground and runs off the concrete)

Answer 7

Erosion is the end product of the interaction between the complex processes of weathering and the processes  of transportation. Snap Snap. Rude bloody Pommy b*****d/
