Front

What evidence supports continental drift observed at the Mid-Atlantic ocean ridge?

Back

The ridge was made of new material while the land around it was older material.

Front

Back

Transform boundary.

Front

____________ boundary occur when tectonic plates move away from each other.

Back

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with each other.

Front

What is the lithosphere?

Back

The rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where plates move towards each other, often causing one plate to be forced below another.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where plates move away from each other, leading to the formation of new crust.

Front

What is a transform boundary?

Back

A tectonic plate boundary where plates slide past each other horizontally.
