Front

What are tectonic plates?

Back

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

Front

What is the movement of tectonic plates?

Back

Tectonic plates are constantly moving due to convection currents in the mantle.

Front

What is continental drift?

Back

The theory that continents have moved over geological time and were once joined together as a supercontinent.

Front

What evidence supports the theory of continental drift?

Back

Fossil discoveries, similar rock formations, and the fit of continental coastlines.

Front

What is Pangaea?

Back

A supercontinent that existed around 240 million years ago, where all continents were joined together.

Front

What forms when two oceanic plates converge?

Back

Volcanic islands can form as a result of this convergence.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, often forming mountains or causing earthquakes.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move apart, often creating new crust.

Front

What is a transform boundary?

Back

A tectonic plate boundary where two plates slide past each other, causing earthquakes.

Front

What geological feature is formed at a convergent boundary?

Back

Mountain ranges are commonly formed at convergent boundaries.
