2022 CHEM FINAL REVIEW Plate Tectonics

Front

What are the layers of the Earth in order from the surface?

Back

Crust, Mantle, Outer Core, Inner Core

Front

What theory explains that continents were once joined together and drifted apart?

Back

Continental Drift

Front

What is a transform boundary?

Back

A type of plate boundary where two tectonic plates slide past each other.

Front

What are the two types of crust?

Back

Continental and Oceanic

Front

Why was Alfred Wegener's theory of Continental Drift not immediately accepted?

Back

There was no mechanism to explain how Continental Drift happened.

Front

What is the Plate Tectonic Theory?

Back

A scientific theory that describes the large-scale movements of Earth's lithosphere.

Front

What is a convergent boundary?

Back

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

Front

What is a divergent boundary?

Back

A boundary where two tectonic plates move away from each other, often creating new crust.

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The semi-fluid layer of the mantle beneath the lithosphere that allows for tectonic plate movement.
