All of the following: ice, tree roots, burrowing animals and carbonic acid cause mechanical weathering EXCEPT
what is carbonic acid
100
Eroded soil can enter streams, causing them to fill with ___________
What is sediment
100
Many farmlands of the Midwestern US are on fertile soil that developed from
What is loess deposits
100
This occurs when glacial ice melts and the water flows down into cracks in rocks, refreezes, fractures the rock into pieces.
What is plucking

Trees, walls and leaning fence posts are signs of this

Wind, water, gravity and glacier are
What is the four agents of erosion
300
This forms when sediments are blown against an obstacle and settle behind it.
What is a dune
300
A large mass of ice and snow slowly moving
What is a glacier
300
The dropping of sediments as they lose energy

500
A ridge or pile of sediment left at the end of a glacier
What is a moraine
500
Mass of material slips down along a curved surface when the base material can no longer support the rock and sediment above.
