What is physical weathering?

400

Mass wasting in which land moves downhill extremely slowly. 

What is a creep?

What is rockslide?

500
Caused by pollution - causes the chemical breakdown of rocks.
What is acid precipitation?
500
Very fast moving erosion in which rocks tumble down a hill causing other rocks to fall as well.
What is rock slides?
500
Animal burrowing in the ground letting in air and water.
