Convergence of India and Asia.

Front

Where is the oldest rock typically found in relation to mid-ocean ridges?

Back

Farthest from the ridge, often at continental margins.

Front

How do the plates move along the San Andreas Fault?

They slide past one another.

Front

What is seafloor spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.

Front

What geological feature is formed at a convergent boundary?

Back

Mountains, trenches, or volcanic arcs.

Front

What is the significance of the Mid-Atlantic Ridge?

Back

It is a divergent boundary where seafloor spreading occurs.

Front

What happens at a transform boundary?

Back

Plates slide past each other horizontally.

Front

What is subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle.
