Earth's Layers

Front

What is the Lithosphere?

Back

The Lithosphere is the outermost layer of the Earth, consisting of the crust and the upper part of the mantle. It is rigid and broken into tectonic plates.

Front

What is the Outer Core?

Back

The Outer Core is a liquid layer of the Earth located beneath the mantle and above the Inner Core. It is primarily composed of iron and nickel.

Front

What is the Inner Core?

Back

The Inner Core is the solid innermost layer of the Earth, composed mainly of iron and nickel, and is extremely hot.

Front

What is the Asthenosphere?

Back

The Asthenosphere is a semi-fluid layer of the upper mantle that lies beneath the Lithosphere. It allows tectonic plates to move.

Front

What is the Mantle?

Back

The Mantle is the thick layer of the Earth located between the crust and the outer core. It contains convection currents that drive plate tectonics.

Front

What are Convection Currents?

Back

Convection currents are movements within the Earth's mantle caused by the heat from the core, which helps in the movement of tectonic plates.

Front

What is the difference between the Outer Core and Inner Core?

Back

The Outer Core is liquid, while the Inner Core is solid.

Front

What is the Crust?

Back

The Crust is the thin, outermost layer of the Earth where we live. It includes both continental and oceanic crust.

Front

What is the Mesosphere?

Back

The Mesosphere is the layer of the mantle located below the Asthenosphere and above the Outer Core. It is more rigid than the Asthenosphere.

Front

What is the composition of the Earth's Inner Core?

Back

The Inner Core is primarily composed of iron and nickel.
