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
