McC 8 Atmosphere

Atmosphere & Climate

atmosphere thin layer of air that forms a protective covering around the planet.
troposhpere the lowest of Earth's atmospheric layers; contains 99% of all the water vapor and 75% of all atmospheric gases; rain, snow, and clouds form here and this layer extends up to 10 km.
stratosphere extends from 10-50km above the surface of the Earth; contains a gas called ozone.
mesosphere from 50-85 kmm above the surface of the Earth; shooting stars can be seen in this layer.
thermosphere named for its high temperatures,; the thickest of all atmospheric layers and extends from 85 km to 500 km above the Earth.
ionosphere an electrically charged layer of the atmosphere within the thermoshere; this layer allows radio waves to travel across the country
exosphere layer having very few air molecules; where the space shuttle orbits the Earth.
ozone layer extends from 19-48 km above the Earth's surface; made of 3 oxygen molecules and necessary for life since it shields us from the Sun's ultraviolet radiation.
ultraviolet radiation one of the many types of energy that comes to the Earth from the Sun. Too much exposure can damage skin and casue cancer.
cholofluorocarbons group of chemical compunds used in various industries, that when leaked into the atmospher can attach to oxygen molcules in ozone and destroy the ozone molecule
radiation energy that is transferred in the form of rays or waves.
conduction the transfer of energy that occurs when molecules bump into one another
convection the transfer of heat through the flow of material
hydrosphere all of the water on the Earth's surface
condensation process of water vapor changing into a liquid
Coriolis Effect the result of the Erath's rotation which causes moving air and water to appear to turn to the right north of the equator and left south of the equator.
sea breeze created during the day becasue solar radiation warms the land more than the water so wind blows from the sea toward the land.
land breeze movement of the air toward the water from the land.
climate the pattern of weather that occurs in an area over many years
tropics the region between latitudes 23 degrees N and 23 degrees S; receives the most amount of solar radiation because the Sun shines directly over these areas.
polar zone extends from 66 degrees N to 66 degrees S; solar radiation hits the zones at a low angle, spreading energy over a large area.
temperate zone the zone found in between the polar and tropic zones; weather here is moderate
adaptation any structure or behavior that helps an organism survvie in its environement.
hibernation reduction in bodily activity which results in lower body temperatures
seasons short periods of climatic changecaused by changes on the amount of solar radiation on an area
El Nino climatic event that involve the Pacific Ocean and the atmosphere; increased ocean temperatures result
greenhouse effect a natural heating that occurs when certain gases in the Earth's atmosphere trap heat.
global warming average global temperatures of the Earth are rising
deforestation the destruction and cutting down of forests; impacts the amount of carbon dioxide in the atmosphere
