Atmosphere

4th Grade Earth Science.

TermDefinition
Atmosphere a mixture of gases that surrounds Earth. Contains 78% nitrogen, 21% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases, including water vapor
altitude height above sea level or the earth's surface
troposphere The lowest layer of the atmosphere and contains weather. Temperature decreases with higher altitude.
stratosphere the layer of the atmosphere that is above the troposphere. Temperature increases with higher altitude.
ozone a form of oxygen gas inside the stratosphere, absorbs ultraviolet rays from the sun and then releases some of this energy in the form of heat.
mesosphere the layer of the atmosphere between the stratosphere and thermosphere. Temperature dUpper most layer of Earth's atmosphere; has two layers ionosphere and exosphere. Temperature increases with altitude.ecreases with higher altitude.
thermosphere Upper most layer of Earth's atmosphere; has two layers ionosphere and exosphere. Temperature increases with altitude.
radiation The transfer of energy through matter or space as electromagnetic waves (visible light or infred)
conduction The transfer of heat through direct contact of materials of different temperature
convection the transfer of heat thru the movement of a fluid, either a gas or liquid
green house earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane.
gobal warming An increase in the average temperature of the earth's atmosphere, especially a sustained increase sufficient to cause climatic change.
water cycle the continuous process by which water moves from Earth's surface to the atmosphere and back
evaporation a process at which molecules at the surface of a liquid absorb enough energy to change to the gaseous state
condensation water vapor cools and becomes a liquid
precipication when water in the form of ice, rain, sleet, hail, or snow falls to the Earth
transpiration the water that plants give off as part of their respiratory process
run off when precipitation hits the ground, it is either absorbed, or it flows over the surface of the earth
water vapor water in its gas form
ground water water that is in the ground
