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.

A student models convection currents in a laboratory activity. How are the convection currents in the student's model different from the convection currents in Earth's atmosphere and oceans?

• The warm air in Earth's atmosphere and the warm water in Earth's oceans sink instead of rise.

• The heat source for Earth's atmosphere and oceans is the sun, which heats from above instead of below.

• Convection cells in Earth's atmosphere and oceans flow in the same direction instead of opposite directions.

• Cold air in Earth's atmosphere and cold water in Earth's oceans are less dense that warm air and warm water instead of being more dense.
