3.3 Exam Review- Plate Boundaries

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often causing one plate to subduct beneath the other.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, leading to the formation of new crust as magma rises to the surface.

Front

What is a transform boundary?

Back

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

Front

What is stress in geology?

Back

Stress is a force that acts on rock to change its shape or volume.

Front

What type of stress is associated with convergent boundaries?

Back

Compression stress is associated with convergent boundaries.

Front

What type of stress is associated with divergent boundaries?

Back

Tension stress is associated with divergent boundaries.

Front

What type of stress is associated with transform boundaries?

Back

Shearing stress is associated with transform boundaries.

Front

At an OC-OC convergent boundary, which plate subducts?

Back

The older oceanic plate subducts beneath the younger oceanic plate.

Front

What geological features are commonly formed at convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs are commonly formed at convergent boundaries.

Front

What geological features are commonly formed at divergent boundaries?

Back

Mid-ocean ridges and rift valleys are commonly formed at divergent boundaries.
