Earth's atmosphere is held down by

• radiation
• gravity
• magnetism
• conduction

Two gases that make up 99% of Earth's atmosphere

• carbon dioxide & oxygen
• nitrogen & carbon dioxide
• nitrogen & oxygen
• nitrogen & water vapor

Layer of Earth's atmosphere where 75% of the water vapor and carbon dioxide are found

• thermosphere
• mesosphere
• stratosphere
• troposphere

Earth's ozone layer is important because it absorbs

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

Layer of Earth's atmosphere that contains most of the ozone

• thermosphere
• mesosphere
• stratosphere
• troposphere

Coldest layer, meteors burn up in this layer

• troposphere
• stratosphere
• mesosphere
• thermosphere

This layer has very high temperatures (hottest layer), but doesn't feel hot- because it has the lowest air pressure

• troposphere
• stratosphere
• mesosphere
• thermosphere

Why is air pressure greatest at the Earth's surface?

• because of the pressure of oxygen
• because of gravity pulls gas molecules toward the surface
• because of the weight of ice crystals
• because of pollution

Gas with the highest percentage in our atmosphere is

• oxygen
• carbon dioxide
• ozone
• nitrogen
