Earth's Interior Layers

Front

What is the Lithosphere?

Back

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

Front

Where do convection currents occur in the Earth?

Back

Convection currents occur in the Asthenosphere, which is a semi-fluid layer beneath the Lithosphere.

Front

What is the innermost physical layer of the Earth?

Back

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

Front

Which layer of the Earth is completely liquid?

Back

The Outer Core is the layer of the Earth that is completely liquid.

Front

What is the Core made of?

Back

The Core consists of two parts: a solid inner core and a liquid outer core.

Front

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

Back

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

Front

What is the Mantle?

Back

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

Front

What is the Crust?

Back

The Crust is the outermost layer of the Earth, which is solid and relatively thin compared to the other layers.

Front

What is the Asthenosphere?

Back

The Asthenosphere is a semi-fluid layer of the mantle that allows for the movement of tectonic plates.

Front

What role do convection currents play in the Earth's interior?

Back

Convection currents in the mantle help drive the movement of tectonic plates and contribute to geological activity.
