8. Patterns In The Natural World (Mrs. Kline)

Front 1

weather

Back 1

is the state of the atmosphere at a particular point in time. It is also known as the local measurement of temperature, wind speed, humidity, cloud cover, etc.

Front 2

climate

Back 2

the average of weather conditions over a long time (hundreds of years).

Front 3

air pressure

Back 3

the weight of air pressing down on Earth

Front 4

barometric pressure

Back 4

the pushing force of the atmosphere (measured with an instrument called a barometer)

Front 5

humidity

Back 5

The amount of water vapor in the air (measured with an instrument called a hygrometer)

Front 6

global warming

Back 6

The theory that increased concentrations of greenhouse gases are causing the Earth’s surface temperature to warm.

Front 7

troposphere

Back 7

It’s the lowest portion of Earth's atmosphere. It contains approximately 75% of the atmosphere's mass and 99% of its water vapor and aerosols. Day to day weather occurs in the troposphere.

Front 8

precipitation

Back 8

Rain, snow, sleet or hail that falls from clouds in the sky

Front 9

meteorologist

Back 9

A scientist who studies and predicts weather.

Front 10

climatologist

Back 10

someone who is expert in climatology (the scientific study of climate)

Front 11

forecast

Back 11

is a prediction of what the weather will be like in an hour, tomorrow, or next week.

Front 12

water cycle

Back 12

the changes to water when it evaporates into the air, condenses into clouds, and then precipitates back down to the earth's surface in different forms

Front 13

evaporation

Back 13

Physical change in matter from a liquid to a gas

Front 14

water vapor

Back 14

water in the form of an invisible gas

Front 15

condensation

Back 15

the process in which a gas turns into a liquid

Front 16

clouds

Back 16

a visible collection of particles of water or ice suspended in the air, usually at an elevation above the earth's surface

Front 17

percolation (percolate)

Back 17

movement of water downward through openings in the soil to replenish aquifers under the ground.

Front 18

transpiration

Back 18

is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. *tree sweat*

Front 19

run off

Back 19

water that runs along the soil and goes into lakes and rivers

Front 20

storage

Back 20

A lot of the Earth's water does not take part in the water cycle very often., Much of it is stored. The Earth stores water in a number of places. The ocean is the largest storage of water. Around 96 percent of the Earth's water is stored in the ocean. We can't drink the salty ocean water, so fortunately for us, freshwater is also stored in lakes, glaciers, snow caps, rivers, and below the ground in ground water storage.

Front 21

wind

Back 21

the movement of air caused by differences in air pressure

Front 22

ocean

Back 22

One of 5 large bodies of salt water that cover 75% of Earth's surface

Front 23

latitude

Back 23

a measure of how far a place is from the equator

Front 24

elevation

Back 24

height above sea level
