folding and faulting CH2 Flashcards
1
Q
how does a fold occur?
A
when the crust is deformed into different shapes
2
Q
how does a fault occur?
A
crack in the earths crust along which there is movement
3
Q
what is a dome?
A
structure shaped like an upturned bowl
4
Q
explain compression?
A
squeezes and shortens the rock, convergent plate boundaries, results in folding/faulting
5
Q
explain tension?
A
stretches the body of rock, divergent plate boundaries, results in faulting
6
Q
explain shearing?
A
fractures the rock and pushes sections past each other, convergent and transform, results in faulting
