In December, Bill was driving through Florida with his family. As they drove closer to the coast, Bill noticed that the air grew a little cooler. Which of the following statements best explains the temperature difference?

• Air expands at higher temperatures.

• Warm air moves toward the coastline from inland areas.

• The land heats up faster than water, creating a sea breeze.

• The water heats up faster than the land, creating a land breeze.

Wind energy is created by the uneven heating of the Earth’s surface by the Sun. Which of the following best describes how wind works?

• When cool air rises, nearby air that’s warmer rushes in to fill the empty space left behind. The rushing air is what we call wind.

• Cool air produces low air pressure and warm air produces high air pressure. Warm air wants to rise. When warm air rises, cool air will move in and replace the warm air, causing wind.

• During the day, the air above the land heats faster than air over water. This warm air over the land expands and rises, and the cooler air, which is heavier, takes its place, creating wind.

• Cool equatorial air rises higher into the atmosphere and migrates toward the poles. At the same time, warmer, denser air moves over Earth’s surface toward the Equator to replace the cooled air, creating wind.

Which layer of the atmosphere contains Ozone?

• Troposphere

• Stratosphere

• Mesophere

• Thermosphere

The atmosphere that surrounds the Earth is divided into five layers. Which property best distinguishes the layers from each other?

• percentage of precipitation

• changes in the state of matter

• increasing air pressure

• changes in temperature

Ozone is a form of oxygen that has three atoms in each molecule instead of two atoms. The ozone layer protects living things. Which of the following best describes how the ozone layer protects living things?

• the ozone layer does not allow meteorites to hit Earth’s surface

• ten percent of oxygen producing organisms live within the ozone layer

• without this barrier in place, all of the Sun’s radiation would reach Earth

• this protective barrier prevents the frigid air found in space from cooling the planet
