Definitions of Atmospheric Layers

The atmosphere is defined as:

• The layer of gases surrounding the Earth

• The solid outer layer of the Earth

• The Earth's water bodies

• The Earth's core

The troposphere is the lowest layer of Earth's atmosphere. Which of the following statements is true about the troposphere?

• It is the highest layer of the atmosphere.

• It contains most of the atmosphere's mass.

• It is where the ozone layer is located.

• It is the layer where meteors burn up.

The stratosphere is a layer of the Earth's atmosphere. Which of the following best describes its characteristics?

• It is the lowest layer of the atmosphere, where weather occurs.

• It contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.

• It is the outermost layer of the atmosphere, where satellites orbit.

• It is a layer with very high temperatures due to the absorption of solar radiation.

Use the Google and in-class resources to define the following: Mesosphere

• The layer of the Earth's atmosphere above the stratosphere

• The innermost layer of the Earth's atmosphere

• The outermost layer of the Earth's atmosphere

• The layer of the Earth's atmosphere where weather occurs

The thermosphere is a layer of Earth's atmosphere. Which of the following is true about the thermosphere?

• It is the closest layer to Earth's surface.

• It contains the ozone layer.

• It is where the auroras occur.

• It is the coldest layer of the atmosphere.

Which layer of the Earth's atmosphere is known for having the highest concentration of ozone?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

What is the primary function of the ozone layer in the Earth's atmosphere?

• To trap heat and maintain Earth's temperature

• To absorb and scatter ultraviolet solar radiation

• To provide oxygen for living organisms

• To reflect radio waves back to Earth

In which layer of the Earth's atmosphere do most weather phenomena occur?

• Stratosphere

• Troposphere

• Mesosphere

• Exosphere
