Four agents of erosion
Terms in this set (13)
The transportation of sediment at the earth's surface
The most important agent of erosion on earth. Fast water eroded more than slow water.
What are characteristics of sediments eroded by water?
Sediments are weathered and eroded by rivers:
Are smooth and round; and the land often has a v-shaped valley
Wind pushes less than water, eroding only smaller particles and leaving the larger sediments behind.
What are characteristics of sediments eroded by wind?
Wind will "sand-blast":
Creating flat surfaces with tiny holes
Are huge heavy slow moving ice that gouges out the land moving nothing in their path
What are characteristics of sediments eroded by Glaciers?
when they finally melt:
Piles of mixed up sediments and lots of fresh water are left behind.
Carve out a U-shaped valleys
Lots of parallel scratches on the rock left behind
Mass Wasting (gravity)
Gravity pulls all things towards the earths center
What are characteristics of sediments eroded by gravity?
Mixed piles of sediments usually below slumps in the land.
All shapes and sizes
Physical breakdown ; form of physical weathering
When you leave things behind! (Last step)
What is the order?
Deposition(settling in position)
Is where deposition is more common to occur. A rivers mouth
