Layers of the Earth Checkpoint

Front

What is a Divergent Plate Boundary?

Back

A type of plate boundary where two tectonic plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What are Seismic Waves?

Back

Waves of energy that travel through the Earth, produced by earthquakes or man-made explosions, used to study the Earth's interior.

Front

What is the Inner Core?

Back

The innermost layer of the Earth, composed of solid iron and nickel, with extremely high temperatures and pressures.

Front

What is the Outer Core?

Back

The layer of the Earth that is liquid and composed mainly of iron and nickel, responsible for generating the Earth's magnetic field.

Front

What is a Convergent Plate Boundary?

Back

A type of plate boundary where two tectonic plates move towards each other, often causing one plate to be forced beneath another, leading to subduction.

Front

What is a Transform Plate Boundary?

Back

A type of plate boundary where two tectonic plates slide past each other horizontally, often causing earthquakes.

Front

What is the Mantle?

Back

The layer of the Earth located between the crust and the outer core, composed of semi-solid rock that flows slowly.

Front

What is the Crust?

Back

The outermost layer of the Earth, consisting of solid rock, and is where we live.

Front

What is Subduction?

Back

The process by which one tectonic plate moves under another plate and sinks into the mantle, often causing volcanic activity.

Front

What is the role of Seismic Waves in understanding the Earth's interior?

Back

Seismic waves help scientists infer the structure and composition of the Earth's layers by analyzing how these waves travel through different materials.
