6.2 & 6.3 Test Review

Front

What happens when an oceanic plate and a continental plate collide?

Back

The oceanic plate subducts because it is more dense than the continental plate.

Front

What are the three primary forces that move tectonic plates?

Back

Ridge push, slab pull, and convection currents.

Front

Where does most seismic and volcanic activity occur?

Back

Most seismic and volcanic activity occurs where there are plate boundaries.

Front

What is the Pacific Ring of Fire?

Back

The Pacific Ring of Fire is a region of active volcanoes.

Front

What evidence supports the process of seafloor spreading?

Back

Magnetic patterns on the ocean floor.

Front

Define subduction in the context of tectonic plates.

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.

Front

What is a tectonic plate?

Back

A tectonic plate is a massive, irregularly shaped slab of solid rock that makes up the Earth's lithosphere.

Front

Explain the concept of ridge push.

Back

Ridge push is a tectonic process where the elevated mid-ocean ridges push tectonic plates away from the ridge.

Front

What is slab pull?

Back

Slab pull is the force exerted by a sinking plate at a subduction zone, pulling the rest of the plate along.

Front

What are convection currents in the mantle?

Back

Convection currents are the circular movements of molten rock in the mantle caused by heat from the Earth's core.
