Atmosphere

Front 1

atmosphere

Back 1

a mixture of gases that surrounds a planet or moon

Front 2

air pressure

Back 2

the measure of the force with which air molecules push on a surface

Front 3

troposphere

Back 3

the lowest layer of the atmosphere, in which temperature decreases at a constant rate as altitude increases

Front 4

stratosphere

Back 4

the layer of the atmosphere that is above the troposphere and which temperature increases

Front 5

mesosphere

Back 5

the layer of the atmosphere between the statosphere and the thermosphere and in which the temperature decreases as altitude increases

Front 6

thermosphere

Back 6

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

Front 7

radiation

Back 7

the transfer of energy as electromagnetic waves

Front 8

thermal conduction

Back 8

the transfer of energy as heat through a material

Front 9

convection

Back 9

the transfer of thermal energy by the circulation or movement of a liquid or gas

Front 10

greenhouse effect

Back 10

the warming of the surface and lower atmosphere of earth that occurs when water vapor,carbon dioxide and other gases aborbs and reradiate thermal energy

Front 11

global warming

Back 11

a gradual increase in average global temperature

Front 12

wind

Back 12

the movement or air caused by differences in air pressure

Front 13

coriolis effect

Back 13

the apparent curving of the path of a moving object from an otherwise straight path due to the earth's rotation

Front 14

polar easterlies

Back 14

prevailing wings that blow from east to west between 60 and 90 latitude in both hemishperes

Front 15

trade winds

Back 15

prevailing winds that blow northeast from 30 north latitude to the equator and that blow southeast from 30 south latitude to the equator

Front 16

jet stream

Back 16

a narrow belt of stong winds that blow in the upper troposphere

Front 17

westerlies

Back 17

prevailing winds that blow from west to east between 30 and 60 latitude in both hemispheres
