Unit 5 Topic 2 Flashcard

Front

What causes the movement of tectonic plates?

Back

Convection currents in the mantle.

Front

What is a convergent boundary?

Back

A boundary where tectonic plates move toward one another, often causing mountains to form when both plates are continental, or subduction when one is oceanic.

Front

What geological feature is formed at a convergent boundary?

Back

Mountains, earthquakes, and volcanoes.

Front

What is a divergent boundary?

Back

A boundary where tectonic plates move away from each other, commonly forming mid-ocean ridges.

Front

What geological feature is commonly formed at a divergent boundary?

Back

Mid-Ocean Ridge.

Front

What is a transform boundary?

Back

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

Front

What happens at a subduction zone?

Back

One tectonic plate is forced under another, leading to volcanic activity and earthquakes.

Front

What is the definition of tectonic plates?

Back

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

Front

What is the lithosphere?

Back

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

Front

What is the mantle?

Back

The layer of the Earth between the crust and the core, where convection currents occur.
