Which of the following is (are) correct about the earth's atmosphere?

• The density of earth's atmosphere is greatest at earth's surface

• Air pressure increases as you go farther from earth's surface

• The majority of air molecules are found far out in space, away from earth's surface

• The troposphere is where the majority of earth's weather occurs

The greenhouse effect occurs primarily in the

• troposphere

• stratosphere

• thermosphere

• mesosphere

Which of the following is NOT a greenhouse gas?

• carbon dioxide (CO₂)

• tropospheric ozone (O₃)

• nitrous oxide (N₂O)

• water vapor (H₂O)

• nitrogen gas (N₂)

Stratospheric ozone is important because it

• keeps out harmful UV radiation from reaching earth's surface.

• prevents smog from forming in urban areas.

• protects earth's surface from visible light and infrared radiation.

• contains the majority of birds and other organisms in the atmosphere.

What is the order of the layers of the atmosphere

• Troposphere, Stratosphere, Thermosphere, Mesosphere

• Troposphere, Stratosphere, Mesosphere, Thermosphere
