Water Cycle & WeatherChapter 6


L1 Where is Earth’s water?

Earth – The water planet

  • People use water to travel

  • ¾ of surface is covered by water

  • It provides a home & food

  • 3 states of water

    • Solid (frozen)

    • Liquid (melted)

    • Gas (invisible water vapor)


Atlantic & Pacific Oceans


Arctic & Indian


Southern Ocean

< 1%

Oceans

Seas

97%

  • Lakes

  • Rivers


“Water, water, everywhere, Nor any drop to drink”

Salt Water

Fresh Water


Salt v. Fresh

Water table

  • Most of the fresh water is frozen in the polar ice caps and glaciers

  • You cannot drink salt water

  • It has dissolved solids in it

    • Salt from rocks & soil

    • Rivers carry salt to the ocean

    • We use ocean salt on food


Saltiness

MORE

LESS

Ocean water is less salty near the North and South Poles where the water evaporates less quickly

Fresh water is found in glaciers and ice caps but it is not safe to drink

Safe fresh water is found underground or in lakes, rivers, and streams

  • Warm places where water evaporates quickly allows more salt to be quickly left behind (salt does not evaporate)

  • Red Sea is very salty because there are deserts on three sides

  • Most of Earth’s water is salty ocean water


L2 Water Cycle

  • Water is recycled

  • No new water is created

  • Water is cleaned through the water cycle

  • Water is always moving

    • The movement is called the water cycle


Water Cycle


The Water Cycle

  • Evaporation – process of changing liquid water to water vapor when it is heated

  • Condensation – process of water vapor becoming liquid water when it cools

  • Precipitation - any form of water that falls to Earth

  • Storage (collection) – water from precipitation sinks into soil, or it falls, flows, or seeps into the ocean


Sun’s Energy = powers the water cycle


Earth’s Atmosphere

  • The protective blanket that surrounds Earth

  • It has mass and takes up space

  • Is a mixture of gases

  • The layer closest to us has water vapor

  • Gravity pulls the mass of air to the surface


Cumulus Clouds

  • Thick clouds, white, & puffy, like piles of cotton, they appear in fair/good weather and may reach high in the sky


Stratus Clouds

  • Flat layers of clouds, that form close to Earth’s surface


Cirrus Clouds

  • Feathery clouds that form high in the atmosphere when water vapor turns to tiny crystals of ice


L4meteorologists

Ben Tanner, WIS-10

Study weather conditions, they look at temperature, water, and air movement, data is collected automatically at weather stations


barometer

  • Air pressure affects weather

  • Air pressure is measured by a tool called a barometer


anemometer

  • Wind affects weather

  • Wind speed is measured by a tool called an anemometer


Wind vane

  • A wind vane shows the direction from which the wind is blowing

  • The pointer points into the wind


Weather maps

  • Use symbols to show fronts and weather conditions in different places
