The major patterns of movement of air and water on Earth are the result of –

• different densities of seawater and fresh water.

• diversity in the height of coastal landforms.

• uneven heating and the rotation of Earth.

• irregular durations of daytime and nighttime.

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.

Convection is the type of heat transfer that occurs in which of the following?

• Empty space

• Solid materials

• Liquids and gases

• Objects in contact

What are the three types of thermal energy transfer?

• Conduction

• Convection

• Radiation

• Condensation

• Radicals

A group of students heats water on a stove to model how the sun drives convection in the atmosphere and oceans. The water at the bottom of the pot heats, expands, rises, cools, and sinks to the bottom. This creates a convection current, similar to those in the atmosphere and oceans. Which statement explains a limitation of this model?

• Heat transfer does not take place by convection

• Temperature changes in water can cause density changes in water

• Air is considered a fluid

• The sun does not transfer heat by conduction
