Atmosphere

mesosphere

the layer of the atmosphere just above the stratosphere; burns up most meteors

respiration

the process by which oxygen combines with food to release energy and carbon dioxide

exosphere

the sub-layer of the thermosphere where the atmosphere blends into space

thermosphere

layer of the atmosphere above the mesosphere where temperatures are the highest in the atmosphere

stratosphere

layer of the atmosphere just above the troposphere where the temperature remains fairly constant

meteorite

mass of stone or metal that has passed through the atmosphere and struck the earth's surface

meteoroid

mass of stone or metal traveling through space

photosynthesis

process by which plants use chlorophyll and energy from sunlight to manufacture food from carbon dioxide

provides gases for respiration and photosynthesis provides protection from UV radiation and meteorites stabilizes a habitable temperature

The atmosphere has many roles, including:
