What causes the movement in atmospheric and oceanic currents?

• Tectonic plates shifting large volumes of air and water

• Radiant heat waves from the core transferring to the air and water

• The Sun's heat causing the density of the air and water to rise and sink

• The Moon's gravitational pull causing the air and water to move slightly away from Earth

• From areas of higher temperature to areas of lower temperature

• from areas of higher pressure to areas of lower pressure

• from areas of lower temperature to areas of higher temperature

When energy from the sun reaches the air above land, the air warms and rises. Along a coastline, cooler air above the ocean flows toward the land to replace this rising air.

Which of the following best describe these processes?

• conduction and convection

• radiation and conduction

• radiation and convection

• conduction, convection and radiation

If you visit the beach on a hot summer day you will probably feel a sea breeze coming off the water onto the land. Which of the following causes this sea breeze?

• the water is warmer than the land during the day

• Earth is tilted toward the Sun, causing air to move inland from the water

• during the day, solar radiation warms the land more than the water

• hurricanes that form in the oceans blow air into the shore

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

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

Why do land breezes occur at night?

• Land cools off slower than water, so the air above water is cooler.

• Water cools off faster than land, so the air above land is warmer.

• Land heats up slower than water, so the air stays cooler during the day.

• Water cools off slower than land, so the air above water is warmer.

How does the air move in a sea breeze?

• wind moves from north to south

• wind moves from ocean to the land

• wind moves from the land to the ocean

• wind moves from south to north
