Layers and Tectonic Plates Review

Front

What is a Convergent Boundary?

Back

A convergent boundary is where two tectonic plates move toward each other, often causing uplift, mountain formation, and earthquakes.

Front

What happens at a Transform Boundary?

Back

At a transform boundary, tectonic plates slide past each other horizontally, which can cause earthquakes.

Front

What is the outer core?

Back

The outer core is the liquid layer of Earth's core that lies beneath the mantle and surrounds the inner core.

Front

What is the theory of Plate Tectonics?

Back

Plate Tectonics is the theory that explains how large pieces of the lithosphere, called plates, are constantly moving.

Front

What is the Asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the mantle located beneath the lithosphere, allowing 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 as magma rises to the surface.

Front

What is the lithosphere?

Back

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

Front

What is the inner core?

Back

The inner core is the solid, innermost layer of the Earth, composed mainly of iron and nickel.

Front

What is the process of subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, often causing volcanic activity.

Front

What is continental drift?

Back

Continental drift is the theory that continents have moved over geological time and were once joined together in a supercontinent.
