Unit 7 Review

What is radiation?

• Energy that travels in waves through space from the Sun to Earth

• The balance between energy received and sent back by Earth

• The absorption of harmful radiation by the ozone layer

• The trapping of heat by gases in Earth's atmosphere

What does Earth's energy budget represent?

• The total energy of motion of particles in a substance

• The balance between the energy Earth receives from the Sun and the energy Earth sends back into space

• The movement of air parallel to Earth's surface

• The apparent curve in the path of winds caused by Earth's rotation

What is the function of the ozone layer?

• It traps heat in Earth's atmosphere

• It absorbs harmful radiation from the Sun and protects living things on Earth

• It measures wind speed

• It moves heat around Earth through ocean currents

What causes the greenhouse effect?

• The movement of air from high-pressure to low-pressure areas

• The trapping of heat by gases in Earth's atmosphere

• The balance of energy received and sent back by Earth

• The apparent curve in the path of winds caused by Earth's rotation

What is thermal energy?

• The energy that travels in waves through space

• The total energy of motion of particles in a substance

• The balance of energy received and sent back by Earth

• The movement of air parallel to Earth's surface

Which of the following is NOT a type of heat transfer?

• Convection

• Radiation

• Reflection

What causes convection currents to form?

• Warm air rises and cooler, denser air sinks

• The movement of air parallel to Earth's surface

• The trapping of heat by gases in Earth's atmosphere

• The absorption of harmful radiation by the ozone layer

What is wind?

• The movement of air parallel to Earth's surface

• The trapping of heat by gases in Earth's atmosphere

• The balance of energy received and sent back by Earth

• The total energy of motion of particles in a substance

What causes wind to form?

• The movement of air from high-pressure areas to low-pressure areas
