Desalination - PowerPoint Presentation

Slide1

Desalination –

Water Cycle

--

Evaporation –

Condensation –

Precipitation –

Water Vapor –

Getting fresh water from sea water.

The continuous movement of water between Earth’s surface and the air, changing from liquid to gas to liquid

the slow changing of a liquid into a gas

water in the form of a gas

the changing of a gas into a liquid

any form of water particles that fall from the atmosphere and reaches the groundSlide2

Groundwater

Reservoir –

Well –

Water Cycle Jump

precipitation that seeps into the ground and is stored in tiny holes, or pores in soil and rocks.

an underground layer of rock or soil filled with water

the top of the water-filled spaces in the ground

a place where groundwater seeps out of the ground

a storage area for

fresh water supplies

a hole dug below the water table that water seeps intoSlide3

Atmosphere –

Troposphere

–

Insolation –

the blanket of gases that surrounds Earth

the layer of the atmosphere closest to the Earth

Incoming SOLar Radia

TION; the amount of the Sun’s energy that reaches Earth at a given time and place.Slide4

Air Pressure –

Isobar

–

Barometer

–

The force put on a given area by the weight of the air above it.

a device for measuring air pressurea line on a weather map connecting places with equal air pressureSlide5

Wind –

Sea Breeze

–

Land Breeze

–

Coriolis Effect –

air that moves horizontally

wind that blows from the sea to land

wind that blows from

the land to sea

the curving of the path of a moving

object caused by Earth’s rotationSlide6

Convection – the flow of heat through a liquid or a gas, causing the hot parts to and cooler parts to

rise

sink.

Convection Cell

–

Air Mass

– Front

–

Cold Front –

Warm Front –

a circular pattern of air rising, air sinking, and wind.

a large region of the

atmosphere where the air has similar properties throughout

a boundary between air masses with different temperatures

a front where

cold air moves in

under a warm

air mass

a front where

warm air

moves in

over a cold

air massSlide7

Thunderstorm –

Tornado

–

the most common severe storm, formed in cumulonimbus clouds

a violent, whirling

wind that moves across theground in a narrow pathSlide8

Hurricane –

Storm Surge

–

a very large, swirling storm with very low pressure at the center

a great rise of the sea along a shore caused by low air pressure.Slide9

Weather –

Climate

–

Humidity

–

Relative Humidity –

what the lower atmosphere is like at any given place and time.the average weather pattern

of a region

the amount of water vapor in

the air

a comparison between how much water vapor is in the air and how much the air could hold at a given temperature if it were full
