Earth's Atmosphere Review

Earth’s early atmosphere consisted of carbon dioxide, water vapor, hydrogen, and nitrogen. During this time in Earth’s early history, the first crust formed and was made of igneous rock. Based on this information, how did Earth’s early atmosphere likely form?

• Release of gases from plant life

• Radioactive decay of igneous rock

• Outgassing from volcanic eruptions

• Accumulation of Gases from space

In addition to carbon dioxide, two other major greenhouse gases in Earth’s atmosphere are

• Oxygen and nitrogen

• Water vapor and methane

• Water vapor and nitrogen

• Oxygen and methane

• 2%

• 21%

• 78%

• 0.4%

The ozone layer protects life on Earth by absorbing harmful UV radiation. The ozone layer is located 17 km – 35 km above Earth’s surface in which atmospheric zone?

• Thermosphere

• Troposphere

• Stratosphere

• Mesosphere

How does air pressure change as you move to higher elevation within the atmosphere?

• Air pressure decreases as you go higher in the atmosphere

• Air pressure increases as you go higher in the atmosphere

• Air pressure decreases and then increases at high altitudes

• Air pressure stays the same at all altitudes

Which of the following statements is FALSE regarding temperature in Earth's atmosphere?

• The thermosphere has the greatest temperature variance of all the layers
