Unit 5 Review

Which atmospheric layer is MOST LIKELY exposed to the least amount of damaging ultraviolet (UV) rays from the Sun?

• A. Stratosphere

• B. Thermosphere

• Mesosphere

• Troposphere

What would most likely happen if Earth did not have an atmosphere?

• Humans and animals would not survive because the oxygen level would increase, but plants would survive because the carbon dioxide level would remain the same.

• Humans and animals would survive because they would have more oxygen to breathe, and plants would survive because the carbon dioxide level would increase.

• Humans and animals would survive because the oxygen level would remain the same, but plants would not survive because the level of carbon dioxide would decrease.

• Humans and animals would not survive because they would not have oxygen to breathe, and plants would not survive without the carbon dioxide provided by humans and animals.

How does the Sun affect the movement of Earth's winds?

• It creates solar winds, which pushes air in Earth's atmosphere and result in currents.

• It warms Earth's surface unevenly, causing changes in air temperature and pressure.

• It has an uneven gravitational pull on Earth's atmosphere, causing changes in pressure and direction.

• It creates solar flares, which energize the winds around Earth's equator and cause them to increase in speed.
