Atmospheric Layers: The concept of Atmospheric Layers

The video explains Earth's atmosphere, focusing on the troposphere and stratosphere. The troposphere, where weather occurs, contains nitrogen, oxygen, and water vapor. It traps heat, making Earth habitable. The stratosphere, with its ozone layer, protects life from ultraviolet radiation. The video also briefly introduces the mesosphere and thermosphere, which shield Earth from high-energy solar radiation.

What is the primary reason weather occurs in the troposphere?

• High levels of ultraviolet radiation

• Rising and sinking motion due to uneven heating

• Horizontal air movement

• The presence of ozone

Which gases are most abundant in the troposphere?

• Carbon dioxide and hydrogen

• Oxygen and argon

• Ozone and nitrogen

• Nitrogen and oxygen

What is the main function of the ozone layer in the stratosphere?

• To absorb ultraviolet radiation

• To trap heat near the ground

• To provide oxygen for breathing

• To create weather patterns

How do thunderstorms behave when they reach the stratosphere?

• They dissipate completely

• They spread out and form an anvil shape

• They become more intense

• They continue to rise

What is the role of the mesosphere and thermosphere?

• To create weather patterns

• To protect from high-energy solar radiation

• To increase air pressure

• To provide oxygen for breathing
