Understanding The Water Cycle Water, water everywhere!

The Earth’s Water  Water covers about 70% of the earth  Of the earth’s water, 80% is in the oceans  The rest of the earth’s water is in the:  Polar Ice Caps  Lakes, rivers, and streams  Glaciers  Water covers about 70% of the earth  Of the earth’s water, 80% is in the oceans  The rest of the earth’s water is in the:  Polar Ice Caps  Lakes, rivers, and streams  Glaciers

Where does Rain Come from? eAeAll water on Earth is linked through the Water Cycle eTeThe Water Cycle is how water moves over the Earth’s surface

Evaporation The Sun heats up bodies of water small or large As water heats up it Evaporates When water evaporates it turns into Water Vapor The water vapor rises in the heated air into the sky

Condensation  As the water vapor rises in the sky it condenses  Condensation occurs as water molecules attach themselves to dust particles and other water molecules  When enough water molecules attach themselves together the form clouds  As the water vapor rises in the sky it condenses  Condensation occurs as water molecules attach themselves to dust particles and other water molecules  When enough water molecules attach themselves together the form clouds

Precipitation eWhen clouds get too heavy with water molecules the water breaks free and falls to the Earth as Precipitation ePrecipitation can fall as: dRain Snow Sleet Hail (Ice)

Recycling the Earth’s Water Recycling the Earth’s Water  When precipitation falls into the oceans it is mixed with the existing water  When precipitation falls over land it collects in lakes, rivers and steams  This water is eventually Recycled to the Earth’s oceans  When precipitation falls into the oceans it is mixed with the existing water  When precipitation falls over land it collects in lakes, rivers and steams  This water is eventually Recycled to the Earth’s oceans
