Exploring Earth's Atmosphere: Layers and Functions

Exploring Earth's Atmosphere: Layers and Functions

Learning Objective

At the end of the lesson, you will understand the structure, composition, and functions of Earth's atmosphere.

What do you already know about the layers of Earth's atmosphere?

What is the Atmosphere?

The atmosphere is a layer of gases surrounding Earth, essential for life. It protects us from solar radiation and helps regulate temperature.

Layers of the Atmosphere

Earth's atmosphere is divided into five main layers: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.

Troposphere

The troposphere is the lowest layer, where weather occurs. It contains most of the atmosphere's mass and is where we live.

Stratosphere

Above the troposphere, the stratosphere contains the ozone layer, which absorbs harmful UV radiation from the sun.

Mesosphere

The mesosphere is where meteors burn up. It is the coldest layer, located above the stratosphere.

Thermosphere

The thermosphere is characterized by high temperatures. It is where the auroras occur and satellites orbit.

Exosphere

The exosphere is
