Continental Drift and Plate Tectonics Review

Front

What is a convergent boundary?

Back

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

Front

What is Pangaea?

Back

Pangaea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all the continents were joined together.

Front

What rises up to create new crust in sea floor spreading?

Back

Magma rises up from the mantle to create new crust during sea floor spreading.

Front

When did the last supervolcano eruption occur?

Back

The last supervolcano eruption occurred approximately 640,000 years ago.

Front

What is the difference between a volcano and a supervolcano?

Back

Supervolcanoes are more powerful and erupt less often compared to regular volcanoes.

Front

What is a divergent boundary?

Back

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

Front

What is a transform boundary?

Back

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

Front

What is the theory of continental drift?

Back

The theory of continental drift suggests that continents have moved over geological time and were once joined together.

Front

What is the role of tectonic plates in earthquakes?

Back

Tectonic plates can cause earthquakes when they move and interact at their boundaries, releasing energy.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate is forced under another, often leading to volcanic activity.
