Earths Layers

Front

What are the three main layers of the Earth?

Back

Crust, Mantle, Core.

Front

What is the Lithosphere?

Back

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

Front

What is the Mantle?

Back

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

Front

What is the Core of the Earth?

Back

The innermost layer of the Earth, consisting of a solid inner core and a liquid outer core.

Front

What is convection current?

Back

The movement of fluid caused by differences in temperature and density, which can occur in the mantle.

Front

Why do less dense gases and liquids rise?

Back

Because they are lighter than the surrounding denser gases and liquids.

Front

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

Back

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

Front

What is the Asthenosphere?

Back

The semi-fluid layer of the mantle just below the lithosphere, allowing tectonic plates to move.

Front

What is the Crust?

Back

The thin, outermost layer of the Earth, where we live.

Front

What causes tectonic plates to move?

Back

Convection currents in the mantle.
