What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move toward each other, often causing one plate to be forced below the other, leading to earthquakes and volcanic activity.

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, creating new crust as magma rises to the surface, often resulting in volcanic activity.

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally, causing friction and earthquakes.

What is compression stress in geology?

Back

Compression stress is a type of stress that occurs when rocks are squeezed together, often leading to the formation of faults and folds.

What is tension stress in geology?

Back

Tension stress is a type of stress that occurs when rocks are pulled apart, which can lead to the formation of normal faults.

Front

What is shearing stress in geology?

Back

Shearing stress is a type of stress that occurs when rocks are pushed in opposite directions, often leading to strike-slip faults.

Front

What is a normal fault?

Back

A normal fault is a type of fault where the hanging wall slips downward relative to the footwall, typically caused by tension stress.

Front

What is a reverse fault?

Back

A reverse fault is a type of fault where the hanging wall moves upward relative to the footwall, typically caused by compression stress.

What is a strike-slip fault?

Back

A strike-slip fault is a type of fault where two blocks of rock slide past each other horizontally, typically caused by shearing stress.

What is the hanging wall in a fault?

Back

The hanging wall is the block of rock that lies above the fault plane.
