• D

Answer explanation

Warm air rise and cool air sinks

warm air is less dense

cool air is more dense so it sinks

An illustration of how a convection current creates a wind, called a land breeze, is provided.Which of the following best explains what creates this convection current?

• The rotation of Earth makes the air above it rotate, but not the same over land and water.

• Because of its mass, Earth’s gravity creates a high pressure area over both the land and water.

• Salt in the ocean makes it more dense than the land, so its gravity pulls more on the air above it.

• During the evening, the land cools off more quickly than the water, so the air is different temperatures.

An illustration of how a convection current creates a wind, called a sea breeze, is provided. Which of the following best explains what creates this convection current?

• Salt in the ocean makes it more dense than the land, so its gravity pulls more on the air above it.

• During the day, the Sun’s energy heats up the land faster, which makes the air above it warmer.

• The rotation of Earth makes the air above it rotate, but not the same over land and water.

• During the day, Earth’s gravity creates a high pressure area over both the land and water.
