Atmosphere Layers WUSO

Which layer of the atmosphere is closest to Earth's surface?

• Stratosphere

• Troposphere

• Mesosphere

• Thermosphere

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

• To trap heat

• To reflect sunlight

• To absorb ultraviolet radiation

• To produce oxygen

Explain how temperature changes as you move through the mesosphere.

• Temperature increases with altitude.

• Temperature decreases with altitude.

• Temperature remains constant.

• Temperature fluctuates randomly.

Describe one characteristic of the thermosphere that distinguishes it from other atmospheric layers.

• It contains the ozone layer.

• It is the coldest layer.

• It has the highest temperatures.

• It is where weather occurs.

Why is the atmosphere important for life on Earth?

• It provides a medium for sound waves.

• It protects us from meteors.

• It contains gases essential for life.

• It reflects sunlight.

Compare the troposphere and stratosphere in terms of weather phenomena.

• Both layers have frequent weather changes.

• Weather occurs only in the stratosphere.

• Weather occurs only in the troposphere.

• Neither layer experiences weather.

What reasoning can you provide for the decrease in temperature with altitude in the troposphere?

• The air is denser at higher altitudes.

• The sun's rays are weaker at higher altitudes.

• The ground absorbs and radiates heat, warming the air above it.

• There is more oxygen at higher altitudes.

Identify the atmospheric layer where most meteors burn up upon entering Earth's atmosphere.
