Exploring the Atmosphere

The video explains Earth's atmosphere, a complex system of five layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has unique characteristics, such as temperature and particle composition. The troposphere is the densest and where weather occurs. The stratosphere contains the ozone layer, protecting Earth from UV rays. The mesosphere is the coldest, where meteors burn up. The thermosphere is hot and where satellites orbit. The exosphere is the outermost layer, where atoms escape into space. These layers have evolved over time but continue to protect life on Earth.

What is the primary function of Earth's atmosphere?

• To support the growth of plants

• To protect the planet from harmful solar radiation

• To provide oxygen for breathing

• To regulate the Earth's temperature

Which layer of the atmosphere is known for containing the ozone layer?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

What is a unique feature of the mesosphere?

• It is the densest layer

• It is where meteors burn up

• It is the warmest layer

• It contains the ozone layer

Why is the thermosphere extremely hot?

• Due to its proximity to the Sun

• Because of the dense air molecules

• Because it absorbs heat from the Earth

• Due to direct energy from the Sun

In which layer do atoms and molecules escape into space?

• Troposphere

• Stratosphere

• Exosphere

• Mesosphere
