Plate Tectonics

Front

What is the lower mantle?

Back

The lower mantle is solid material extending to Earth's core.

Front

What is common at convergent boundaries?

Back

Mountains are commonly formed at convergent boundaries.

Front

What was the name of the supercontinent where all continents were once together?

Back

The supercontinent is called Pangaea.

Front

How fast do continents move?

Back

Continents move at a rate of 3-4 inches per year.

Front

What geological events often occur at transform boundaries?

Back

Earthquakes often occur at transform boundaries.

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 the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer beneath the lithosphere that allows tectonic plates to move.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often creating new crust.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, leading to the formation of mountains or subduction zones.
