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
|
