Earth's Atmosphere

Why does the troposphere experience (have) the greatest amount of atmospheric pressure compared to the other atmospheric layers?

• It produces the ozone layer.

• It has the highest temperatures.

• It contains a high concentration of gas particles.

• It is the region in which weather occurs.

Which of these statements BEST describes (explains) temperature as elevation in the atmosphere increases?

• Temperature remains constant with elevation in the thermosphere.

• Temperature remains constant with elevation in the mesosphere.

• Temperature generally decreases with elevation in the stratosphere.

• Temperature generally decreases with elevation in the troposphere.

The BEST description of the troposphere is the layer of the atmosphere with the

• most ozone.

• greatest density.

• highest altitude.

• coldest temperature.

An atmospheric layer of a specific (exact) gas provides (gives) shielding (protection) from harmful ultraviolet light from the Sun, allowing life to thrive (live) on Earth. What gas makes up this layer?

• H₂O

• CO₂

• N₂

• O₃

Atmospheric greenhouse gases help heat the atmosphere by

• increasing the amount of solar radiation reaching Earth.

• storing energy produced by human activity.

• absorbing infrared radiation released by Earth.

• increasing the average density of air.
