Plate Tectonics Review

Front

What is a convergent boundary?

Back

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

Front

What happens at a convergent boundary?

Back

At a convergent boundary, plates collide, which can lead to the formation of mountains, earthquakes, and volcanic activity.

Front

What is the evidence of Wegener's Theory related to ancient organisms?

Back

Fossils are the remains of ancient organisms that provide evidence for Wegener's Theory of continental drift.

Front

What occurs when oceanic crust and continental crust converge?

Back

When oceanic crust and continental crust converge, it often results in volcanic activity.

Front

What is created when two continental crusts push together?

Back

When two continental crusts push together at a convergent boundary, they create mountains.

Front

Define a transform boundary.

Back

A transform boundary is where two tectonic plates slide past each other horizontally, often causing earthquakes.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, leading to the formation of new crust.

Front

What is sea-floor spreading?

Back

Sea-floor spreading is the process by which new oceanic crust is formed at divergent boundaries as magma rises to the surface.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate is forced under another, often leading to volcanic activity.
