7.e.1.1 layers of atmosphere quiz

Which statement best explains the cause of atmospheric air pressure?

• Air molecules are pulled to Earth by gravity.

• Air molecules are pushed to Earth by gravity.

• The thermal energy of air molecules makes them become heavier and they sink to Earth.

• The potential energy of air molecules makes them lighter and they rise into the atmosphere.

Which statement describes the air pressure in the atmosphere as the distance above Earth’s surface increases?

• Air pressure increases.

• Air pressure decreases.

• Air pressure remains constant.

• There is no air pressure above the surface.

In which layer are molecules most likely to escape Earth’s atmosphere?

• exosphere

• stratosphere

• thermosphere

• troposphere

Which statement best describes the mesosphere and exosphere?

• Both layers increase in temperature with increased altitude.

• Both layers decrease in temperature with increased altitude.

• The mesosphere increases in temperature, while the exosphere decreases in temperature with increased altitude.

• The mesosphere decreases, while the exosphere increases in temperature with increased altitude.

Which gas is second in abundance in Earth's atmosphere?

• carbon dioxide

• nitrogen

• oxygen

• water

Air pollution can cause holes in the ozone layer. How are holes in the ozone layer likely to impact people on Earth?

• More UV rays reach Earth's surface and cause damage to human skin.

• The holes allow too much heat to escape the atmosphere, and people become cold.

• More UV rays reach Earth's surface and prevent human skin from absorbing Vitamin D.

• The holes prevent heat from escaping from the atmosphere, and people become too warm.

Which statement best describes the troposphere and stratosphere?

• Both layers increase in temperature with increased altitude.

• Both layers decrease in temperature with increased altitude.

• The troposphere increases in temperature, while the stratosphere decreases in temperature with increased altitude.

• The troposphere decreases in temperature, while the stratosphere increases in temperature with increased altitude.

How does air density change as altitude increases?

• Air density increases due to the increased space between molecules.

• Air density decreases due to the increased space between molecules.

• Air density increases due to the decreased space between molecules.

• Air density decreases due to the decreased space between molecules.
