What is a transform boundary?

Back

A transform boundary is a type of tectonic plate boundary where two plates slide past each other, often causing earthquakes.

Front

What geologic event is most likely found at a transform boundary?

Back

Earthquake.

Front

What drives the movement of tectonic plates?

Back

Convection currents in the asthenosphere.

Front

What is Pangaea?

Back

Pangaea was a supercontinent that existed millions of years ago, where all continents were once joined together.

Front

What evidence did Alfred Wegener provide for the theory of continental drift?

Back

Matching fossil records, similar rock layers, and coastlines of continents matching like a jigsaw puzzle.

Front

What does the theory of continental drift state?

Back

The theory states that all continents were once joined together and have since drifted apart.

Front

What are convection currents?

Back

Convection currents are movements within the Earth's mantle caused by the heat from the core, driving the movement of tectonic plates.

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the mantle beneath the lithosphere, where convection currents occur.

Front

What is a supercontinent?

Back

A supercontinent is a large landmass that contains multiple continents, such as Pangaea.
