Layers of the Earth

Lithosphere

The rigid outer layer of the Earth, composed of the crust and the upper mantle, which is involved in tectonic processes such as plate movement.

Asthenosphere

A semi-fluid layer beneath the lithosphere, enabling tectonic plate movement.

Troposphere

The lowest layer of Earth's atmosphere, where weather occurs and where air pressure and temperature decrease with altitude.

Stratosphere

Layer above the troposphere, home to the ozone layer, where temperatures increase with altitude.

Mesosphere

Middle layer of the atmosphere, characterized by decreasing temperatures with altitude and meteoroid disintegration.

Thermosphere

The uppermost layer of the atmosphere, characterized by high temperatures and very low air density. It is where the ionosphere is located, enabling radio communication.

Ionosphere

Part of the thermosphere, containing ionized particles that reflect radio waves and are crucial for communication.

Exosphere

The outermost layer of Earth's atmosphere, where satellites orbit and gases are extremely sparse.
