Continental Drift & Plate Tectonics

Front

What is the densest type of crust?

Back

Oceanic crust is the densest type of crust.

Front

When an oceanic plate and a continental plate collide, which one will subduct?

Back

The oceanic plate will subduct.

Front

What type of boundary is the San Andreas Fault?

Back

The San Andreas Fault is an example of a transform boundary.

Front

What evidence did Wegener study to support his ideas about continental drift?

Back

Wegener studied matching land features (rocks and land) and continental fit.

Front

What does a divergent boundary represent?

Back

A divergent boundary represents where two oceanic crusts are moving away from each other.

Front

What is the main theory that explains the movement of Earth's plates?

Back

The theory of plate tectonics explains the movement of Earth's plates.

Front

What are tectonic plates?

Back

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

Front

What happens at a convergent boundary?

Back

At a convergent boundary, two tectonic plates move towards each other, often causing one plate to subduct.

Front

What is subduction?

Back

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

Front

What geological features are commonly formed at convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs are commonly formed at convergent boundaries.
