Atmosphere

the mass of air surrounding the Earth. Its important because it protects people from the U.V rays.

particulates

Small particles of dust released into the atmosphere by many natural processes and human activities

Gases in the atmosphere

78% Nitrogen,.9% Argon, 20% Carbon Dixoide

Atmospheric Pressure

the pressure caused by the weight of the atmosphere. The tool use to find it is called a baramoter.

Earth is

4.6 billion years old

Outgassing

release of gasses from Earth's interior. In the earely stages volcanes brought outgassing.

Troposphere

the layer closest to Earth, where almost all weather occurs; the thinnest layer

startosphere

the layer above the troposphere where airplanes fly in.

Mesosphere

the layer middle layer and temperature decreases as altitude increases

Thermosphere

The uppermost layer of the atmosphere, in which temperature increases as altitude increases

Temperature

the degree of hotness or coldness of a body or environment (corresponding to its molecular activity).

Ozone

a form of oxygen that has three oxygen atoms in each molecule instead of two. protects us from dangerous ultraviolet radiation from the sun

Inosphere

layer of electrically charged particles in the thermosphere that absorbs AM radio during the day and reflects at night

Source

(technology) a process by which energy or a substance enters a system

EM Spectrum

Range of EM frquencies including radio waves, microwaves, infrared, visible, UV, x-rays, and gamma rays.

Absorbed

taken in through the pores of a surface

Reflected

light, sound, images or heat that strikes a surface and bounces back

Scattered

occurring or distributed over widely spaced and irregular intervals in time or space

Albedo

the ratio of reflected to incident light

Terrestrial Radiation

The radiation emmited by the Earth to outer space

Greenhouse effect

warming that results when solar radiation is trapped by the atmosphere

Greenhouse gases

Gases such as carbon dioxide, methane, nitrous oxide, water vapor, and ozone in the atmosphere which are involved in the greenhouse effect.

Wind

air moving (sometimes with considerable force) from an area of high pressure to an area of low pressure

Uneven Heating

sets up patterns of precipitation & prevailing winds, warm air-less dense, collect moisture, rises, cool air-more dense, loses moisture, descends

Convection

the transfer of heat through a fluid (liquid or gas) caused by molecular motion

Coriolis effect

(physics) an effect whereby a body moving in a rotating frame of reference experiences the Coriolis force acting perpendicular to the direction of motion and to the axis of rotation

Wind Belts

formed when air moves out of a high cell to a low cell

Doldrums

a state of inactivity (in business or art etc)

horse latitudes

are regions of high pressue and gentle winds at about 30 degrees north and south latitude

Westerlies

prevaling winds that blow from west to east between 30 degrees & 60degrees latitude in the hemisphere.

Polar easterlies

Prevailing winds that blow from east to west between 60degrees-90degrees latitude in both hemisphere.

trade winds

winds that blow across the Atlantic Ocean west toward the Caribbean

Hadley Cells

convection currents 0-30 degrees north and south of the equator

land brezze

a local wind that blows from the land toward a large body of water

sea brezze

the wind that blows from the sea to land
