Unit 5:atmosphere

Front 1

ozone layer

Back 1

a layer of the stratosphere with a high concentration of ozone; protects living things by absorbing ultraviolet radiation from the sun

Front 2

water cycle

Back 2

the continuous movement of water between the Earth's surface and the atmosphere through evaporation, condensation, and precipitation

p.406

Front 3

jet stream

Back 3

narrow wind belts occurring near the top of the troposphere
p. 414

Front 4

sea breeze

Back 4

wind blowing from sea to land during the day when the sun warms the land faster, and cool air from above the water forces the warm air above the land to rise
p. 414

Front 5

*ozone

Back 5

a naturally occuring gas in the stratosphere; also occurs in smog in lower levels of the atmosphere as a pollutant

Front 6

land breeze

Back 6

wind blowing from land to sea at night because the land cools faster and cool air over the land moves out over the sea

p.415

Front 7

ultraviolet radiation

Back 7

a type of energy that comes to Earth from the sun and is mostly absorbed by the ozone layer; rays can damage skin and cause cancer and other health problems

p.400

Front 8

meteorologist

Back 8

a scientist who studies weather conditions using radar, satellites, and other instruments to make weather maps and forecasts
p. 440

Front 9

ionosphere

Back 9

a layer of Earth's atmosphere, where ions and free electrons absorb AM radio waves during the day and reflect them back toward earth at night

p.395

Front 10

*atmosphere

Back 10

the gaseous mass surronding the earth and retained by the earth's gravitational pull

Front 11

troposphere

Back 11

the layer of earth's atmosphere closest to the ground; contains clouds, smog, weather, and 75% of the atmospheric gases

p.394

Front 12

hydrosphere

Back 12

all the water that occurs at Earth's surface

p. 406

Front 13

Coriolis effect

Back 13

khor ee OH lus

the effect of Earth's rotation on the movement of air masss; changes the direction of the air flow
p.411

Front 14

conduction

Back 14

the transfer of heat that occurs when molecules collide

p.405

Front 15

meterology

Back 15

The study of earth's weather anded the forces that cause it

Front 16

convection

Back 16

the transfer of heat by a flow of a heated material; occurs in gases or liquidsp. 405

Front 17

chloroflurocarbons

Back 17

a group of chemicals used in refrigerators, aerosol sprays, and foam packaging ; destroy ozone molecules

Front 18

radiation

Back 18

the transfer of energy through matter or space by electromagnetic waves
