Weather and Climate

What is the most abundant gas in Earth’s atmosphere?

• oxygen

• nitrogen

• carbon dioxide

• methane

Which layer of the atmosphere is the least dense?

• exosphere

• stratosphere

• troposphere

• mesosphere

Which statement best describes heating by radiation?

• Air molecules touch the warm ground, heating them up.

• Warm air rises and takes heat with it; eventually it cools and sinks.

• Sunlight travels through space without the aid of fluids or solids.

• Air at the equator rises and sinks at the poles.

Which statement refers to convection?

• Some of this energy is reflected off Earth's atmosphere.

• Warm air rises and takes heat with it; eventually it cools and sinks.

• Sunlight travels through space without the aid of fluids or solids.

• Land and ocean absorb and re-emit heat from the sun.

Which statement best describes the relationship between changes in air pressure and wind speeds?

• When a high- and a low-pressure air mass are far apart, air moves quickly from low to high pressure.

• When a high- and a low-pressure air mass are far apart, air moves slowly from high to low pressure.

• When a high- and a low-pressure air mass are close together, air moves slowly from high to low pressure.

• When a high- and a low-pressure air mass are far apart, air moves quickly from high to low pressure.
