Atmosphere
Earth's air, which is made up of a thin layer of gases, solids, and liqids forms a protective layer around the planet and is divided into 5 layers.
chloroflurocarbon
(CFC's)
group of chemical compounds used in fridges, foam packaging.. etc. that may destroy ozone. ILLEGAL.
condensation
change of matter from a gas to a liquid state (water vapor to liquid)
convection
transfer of heat by flow of material
conduction
transfer of energy that occurs when molecules bumb into each other.
Coriolis effect
causes moving of air and water to turn left in southern hemisphere and right in northern hemisphere due to earth's rotation
hydrosphere
all of water on Earth's surface
ionosphere
layer of electrically charged particles in between mesosphere and thermosphere. AM radio.
jetstream
narrow belt of strong winds that blows near top of the troposphere
land breeze
movement of air from land to sea at night; created when cooler, denser air from the land forces up warmer air over the sea.
ozone layer
layer of the stratosphere with a high concentration of ozone; absorbs most of the Sun's harmful ultraviolet radiation
radiation
energy transferred by waves or rays
sea breeze
movement of air from sea to land during the day when cooler air from sea moves over the land, forcing the heated, less dense air above the land to rise
troposphere
layer of earth's atmosphere that is closest to the ground; contains 99% of water vapor, 75% atomospheric gases, clouds and weather here
ultraviolet radiation
type of energy that comes to earth from the sun, can damage skin and cause cancer, is mostly absorbed by ozone layer
3 trace elements
argon, carbon dioxide, hydrogen
percents of atmosphere
78% nitrogen, 21% oxygen, 1% trace
layer closest to the earth : 0-10m
troposphere
2nd layer: 10-50m
Stratosphere
layer inside the Statosphere
ozone
3rd layer in atmosphere : 50-85m (coldest)
Mesosphere
layer between meso and thermo : AM radio
Ionosphere
4th layer in atmosphere: 85-500m (hottest)
Thermosphere
outerspace
Exosphere
temp. of troposphere
as you go up in that layer it gets cooler
Westerlies
Near 30* N and S. Moves from west to east.
Doldrums
Along equator; heating causes air to expand..... creating a zone of low pressure
Trade Winds
from any direction to equator
Polar Easterlies
move from poles ; east to west
