Continental Drift and Plate Tectonics Review

Front

What is Continental Drift?

Back

The theory that continents have moved over geological time and were once joined together in a single landmass called Pangaea.

Front

What is Plate Tectonics?

Back

The scientific theory that explains the movement of Earth's plates and how they interact at their boundaries.

Front

What is a Subduction Zone?

Back

A region where one tectonic plate moves under another plate and sinks into the mantle, often forming volcanoes.

Front

What is a Hotspot?

Back

A location where magma from deep within the mantle rises to the surface, creating volcanoes, independent of plate boundaries.

Front

What type of boundary is formed when two tectonic plates move apart?

Back

Divergent boundary.

Front

What type of boundary is formed when two tectonic plates collide?

Back

Convergent boundary.

Front

What is a Transform Boundary?

Back

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

Front

What is the Asthenosphere?

Back

The semi-fluid layer of the mantle beneath the lithosphere, from which magma is generated.

Front

How do Volcanoes form at Subduction Zones?

Back

When an oceanic plate subducts beneath a continental plate, it melts and forms magma, which can lead to volcanic eruptions.

Front

What are Island Arcs?

Back

Curved chains of volcanic islands that form at convergent boundaries, typically where an oceanic plate subducts beneath another oceanic plate.
