What happens when water freezes?
It expands by about 10%
It expands by about 50%
It shrinks by about 10%
It shrinks by about 50%
vegetation root action occurs when
scrubs and plants form another type of vegetation
The plant grows to become a tree and the roots exert pressure against the rock and breaks it apart.
a drought occurs and plants die, causing the rocks to break down
Describe the process of freeze thaw
Water enters a crack, freezes and expands. Then melts and fills the crack more. Repeat until rock cracks
Water enters a crack, freezes and expands.
Water enters a crack and freezes, then stays like that forever.
Water enters a crack, freezes and melts. This cracks the rock.
