Surface Features and Plate Boundaries

Front

What is the Ring of Fire?

Back

The Ring of Fire is a horseshoe-shaped zone around the Pacific Ocean characterized by a high frequency of earthquakes and volcanic activity.

Front

Where is Iceland located?

Back

Iceland is located in the Arctic Circle.

Front

What is the age pattern of rocks around the Mid Atlantic Ridge?

Back

The rocks are younger closer to the ridge and older further away.

Front

What does density data indicate about the Nazca Plate?

Back

The density data supports the claim that the Nazca Plate is sinking underneath the South American Plate.

Front

Where is new crust primarily formed?

Back

New crust is primarily formed at divergent boundaries.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.

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.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, often resulting in one plate being forced beneath the other.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate sinks beneath another at a convergent boundary.
