Physical Science Chapter 22

Front 1

troposphere

Back 1

the layer of the atmosphere that is closest to the surface of the Earth. Most of our weather happens in the troposphere

Front 2

stratosphere

Back 2

layer above the troposphere. Cold, low-pressured area.

Front 3

ozone layer

Back 3

Warm, upper level of the stratosphere. This layer absorbs much of the sun's ultraviolet radiation.

Front 4

mesosphere

Back 4

coldest layer of the atmosphere, between the stratosphere and troposphere.

Front 5

ionosphere

Back 5

area of the atmosphere where ions form. Without the ionosphere, most radio waves would travel directly into space.

Front 6

auroras

Back 6

colorful light display in the sky. They are formed with ions from the sun his atoms and molecules in the ionosphere.

Front 7

photosynthesis

Back 7

A method of capturing energy from the sun. Produces oxygen as a by-product.

Front 8

aerobic

Back 8

oxygen breathing organism

Front 9

anaerobic

Back 9

not needing oxygen

Front 10

chlorofluorocarbons (CFCs)

Back 10

chemicals that are causing the ozone layer to thin

Front 11

Greenhouse effect

Back 11

Warming of the surface and lower atmosphere of Earth that occurs when carbon dioxide, water vapor, other gases in the air absorb and reradiate infrared radiation.

Front 12

Global warming

Back 12

It too much energy is absorbed by the atmosphere, global temperature will rise.

Front 13

Water cycle

Back 13

Water is continuously being moved through the troposphere.

Front 14

Evaporation

Back 14

Liquid to gas

Front 15

Transportation

Back 15

Plants lose moisture through small pores in their leaves. The moisture goes into the air.

Front 16

Precipitation

Back 16

Water vapor cools enough to become clouds then falls as rain.

Front 17

Humidity

Back 17

Amount of moisture in the air

Front 18

Condensation

Back 18

Water changing from gas to a liquid. ( on the mirror when you take a shower)

Front 19

Dew point

Back 19

Temperature at which the rate of condensation equals the rate of evaporation.

Front 20

Cirrus clouds

Back 20

Thin, wispy. Occur at high levels.

Front 21

Stratus clouds

Back 21

Layered and look like sheets. Occur at lower levels.

Front 22

Cumulus clouds

Back 22

White, fluffy, flat bottom. Flat bottom is where rising air reaches dew point.

Front 23

Barometric pressure

Back 23

Pressure that results. From the weight of a column of air extending from the top of the thermosphere to the point of measurement.

Front 24

Wind

Back 24

A difference in pressure creates winds.

Front 25

Coriolis effect

Back 25

The effect of Earth's on the direction of wind.
