NCFE Review #2 Lithosphere Part II: Plate Tectonics, Earth's Int

Front

What is the process of new crust formation from the mantle?

Back

Magma is pushed up from the mantle to create new crust.

Front

What type of stress squeezes tectonic plates together?

Back

Compression.

Front

What is a subduction zone?

Back

A subduction zone is formed when one tectonic plate sinks below another.

Front

Where can volcanoes be found?

Back

Volcanoes can be found on land, under water, on islands, and in many other locations.

Front

What geological process occurs at a subduction zone?

Back

Subduction occurs, where one plate moves under another.

Front

What is the primary material that forms new crust?

Back

Magma.

Front

What type of plate boundary is associated with compression?

Back

Convergent plate boundary.

Front

What is the result of tension stress on tectonic plates?

Back

Tension causes plates to pull apart.

Front

What is the role of convection currents in plate tectonics?

Back

Convection currents in the mantle drive the movement of tectonic plates.

Front

What happens at divergent plate boundaries?

Back

Two tectonic plates move apart, allowing magma to rise and form new crust.
