Front

What would end Earth's tectonic activity?

Back

Earth's mantle becomes cooler and solid.

Front

Where are mountains most likely to form according to tectonic activity?

Back

At convergent boundaries, such as location B on a tectonic map.

Front

Which of the following is NOT evidence to support the theory of plate tectonics?

Back

Sand Erosion.

Front

What evidence did Wegener use to prove continental drift?

Back

The shape of the continents, similar fossils found on separate continents, and tree fossils found in odd places.

Front

What are tectonic plates?

Back

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

Front

What is continental drift?

Back

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

Front

What is the theory of plate tectonics?

Back

The scientific theory that explains the movement of the Earth's plates and the processes that occur at their boundaries.

Front

What is a convergent boundary?

Back

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

Front

What is a divergent boundary?

Back

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