2. Where Is Water Found? 70% of the Earth is covered by water. 70% of the Earth is covered by water. 97% of all water is found in the oceans 97% of all water is found in the oceans 2% of all water is found in glaciers and ice caps 2% of all water is found in glaciers and ice caps 1% is found in soil water, groundwater, lakes, ponds, rivers, atmosphere, inside plants and animals 1% is found in soil water, groundwater, lakes, ponds, rivers, atmosphere, inside plants and animals

3. Atmosphere The blanket of gases that surrounds Earth. Atmosphere- The blanket of gases that surrounds Earth. Water vaporWater in a gas state. Water vapor- Water in a gas state. The water in the atmosphere is in a gas state.

4. The Atmosphere Most water vapor is found in the troposphere. This is where weather forms. More water vapor is found in the air above water than in the air above land.

5. Underground Water Soil water: water that collects in the soil. It is used by plants. Soil water: water that collects in the soil. It is used by plants. Groundwater: water that soaks through the soil and underground rocks Groundwater: water that soaks through the soil and underground rocks

6. The States of Water Water comes in three different states: solid (ice), liquid, gas (water vapor). Water comes in three different states: solid (ice), liquid, gas (water vapor). A temperature change causes a change in water state. A temperature change causes a change in water state. ---------------colder------------------ ---------------colder------------------ gas waterice gas waterice ------------warmer------------------- ------------warmer-------------------

7. The States of Water Water is matter. All matter is made of small pieces called molecules. Water is matter. All matter is made of small pieces called molecules. The molecules in a solid do not move and are packed together tightly. The molecules in a solid do not move and are packed together tightly. Liquid molecules move slowly around each other. Liquid molecules move slowly around each other. Gas molecules move fast around each other. Gas molecules move fast around each other. A water molecule

8. Changes in State Freeze- the process in which moving particles slow down, lose heat, and change from a liquid to a solid Freeze- the process in which moving particles slow down, lose heat, and change from a liquid to a solid Melt- when water particles absorb heat energy and change from a solid to a liquid Melt- when water particles absorb heat energy and change from a solid to a liquid

9. Remember this from a few weeks ago? What state of water is found in the photos? What changed? What doesnt it look like this anymore outside?
