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.

In which layer of Earth’s atmosphere does weather occur?

• mesosphere

• stratosphere

• thermosphere

• troposphere

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.

• troposphere

Which trait (characteristic) is common in gases that contribute (give) to Earth’s greenhouse effect?

Some jet airplanes fly in a layer of the atmosphere where temperature generally (mostly) increases with altitude. What is this layer of the atmosphere?

• mesosphere

• stratosphere

• thermosphere

• troposphere

In which layer of the atmosphere does MOST of Earth’s weather occur (take place)?

• the exosphere, which is the outermost layer

• the troposphere, which is the lowest layer

• the thermosphere, which has the highest temperature

• the stratosphere, which contains a sub-layer of ozone

How is the stratosphere different from the troposphere?

• The clouds in the stratosphere produce more rain.

• The air in the stratosphere has a greater density.

• The composition of the stratosphere lacks ozone.

• The temperature of the stratosphere warms at higher altitude.
