Atmosphere and Greenhouse Effect

The ozone layer protects us from

• Increased atmospheric heat

• CFCs

• UV rays

• Decreased atmospheric heat

The most abundant gas in the troposphere layer of the atmosphere is

(a)  

The 21% gas in the Earth's atmosphere, produced by plants during photosynthesis is

• carbon dioxide

• nitrogen

• oxygen

Why is the temperature in the stratosphere warmer at the higher altitude?

• In the stratosphere, air temperature is warmer because it is closer to the sun than troposphere.

• In the stratosphere, air temperature increases with height due to the ozone layer that absorbs the sun's rays.

• The ozone layer is on top of the stratosphere, therefore, air temperature is warm at the lower altitudes.

As the altitude increases the air pressure _______

• increases
• decreases

As the altitude increases in the Troposphere, the temperature ________________

• Increases
• Decreases

The farthest layer of the atmosphere from the Earth's surface.

• Troposphere
• Stratosphere
• Mesosphere
• Thermosphere

This is the densest layer of the atmosphere.

• Thermosphere
• Troposphere
• Mesosphere
• Stratosphere
