Convection and the Sun's Energy

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.

Sabrina noticed a lot of puddles on her driveway after it rains on Tuesday afternoon. On Wednesday morning she notices the puddles are gone. Why?

• The wind blew the puddles away

• They disappeared

• The suns energy caused the water to evaporate

• The suns energy caused the water to precipitate
