What percentage of solar radiation is reflected into space by Earth's surface, atmosphere, or clouds?

• About 10 percent

• About 20 percent

• About 30 percent

• About 50 percent

Which of the following objects is likely to absorb energy faster?

• A light-colored concrete driveway on a sunny day

• A black asphalt driveway on a sunny day

• A light-colored concrete driveway on a cloudy day

• A black asphalt driveway on a cloudy day

What is conduction?

• The transfer of thermal energy in a material by the movement of heated material from one place to another.

• The process by which thermal energy is transferred when two objects at different temperatures are in contact.

• The movement of air parcels in the atmosphere due to differences in temperature and density.

• The increase of thermal energy in a material when it is heated on a burner.

Why is air a poor conductor of thermal energy?

• Because it is mainly in a liquid state.

• Because its particles are closer together than in solids.

• Because it is a mixture of gases where particles are farther apart.

• Because it transfers energy mainly through convection.

What is convection?

• The transfer of thermal energy by electromagnetic waves.

• The transfer of thermal energy by the direct contact of particles.

• The transfer of thermal energy in a material by the movement of heated material from one place to another.

• The process of heating a pot of water on a burner.
