Plate Tectonics & Paleontology Common Assessment Review

Front

What is a subduction zone?

Back

A subduction zone is where one tectonic plate slides under another plate.

Front

What are convection currents?

Back

Convection currents are the cycle of heated rock or metal rising, and cooling rock or metal falling.

Front

What is the Asthenosphere?

Back

The Asthenosphere is an elastic substance on which the tectonic plates float.

Front

Which layer of the Earth has the lowest temperature?

Back

The Crust has the lowest temperature.

Front

Who proposed the idea of continental drift?

Back

Alfred Wegener proposed the idea of continental drift.

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 difference between the inner core and outer core?

Back

The inner core is solid and extremely hot, while the outer core is liquid and composed mainly of iron and nickel.

Front

What causes tectonic plates to move?

Back

Tectonic plates move due to convection currents in the mantle.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally.
