Which is a subsurface event?
Water freezes and thaws which breaks rocks.
Deep rock changes due to heat and pressure.
Gravity pulls rocks down hill which breaks them.

2
An example of weathering is....
A tree root grows into a crack and breaks the rocks.
gravity moving a rock down a mountain.
A wave moving sand
a river moving sediment
3
What is cementation?
Gravity pulling everything down squeezing the bottom rocks.
The dropping off of sediment down hill
The movement of sediment in a river
When rock pieces stick together with clay and other minerals
