7 Earth Science - Atmosphere

This gas makes up 78% of the atmosphere

• oxygen

• nitrogen

• ozone

• carbon dioxide

Over Geologic Time, Earth's atmospheric oxygen levels have:

• Increased

• Decreased

• Fluctuated

• Stayed at a constant %

Earth's atmosphere accumulated oxygen primarily due to:

• Land plant respiration

• Microscopic organisms' respiration

• Mamma (human) respiration

• Volcanism

NGSS.MS-ESS2-6

Layer of Earth's atmosphere where most of the water vapor and carbon dioxide is found

• thermosphere

• mesosphere

• stratosphere

• troposphere

NGSS.MS-ESS2-5

Layer of Earth's atmosphere that 'warms' due to ultraviolet (UV) energy absorbed and re-emitted as heat energy.

• thermosphere

• mesosphere

• stratosphere

• troposphere

Earth's ozone layer is important because it absorbs

• visible light
• ultraviolet radiation
• x-rays
• radio waves

The sun's rays are least direct

• near the poles

• near the equator

• at high altitudes

• far from the ocean
