 Where can you find the three states of water? › Liquid: surface water, underground water › Solid: mountain glaciers, ice sheets, polar icecap › Gas: water vapour, › clouds

 Time for a Bill Nye tune... › "Water Cycle Jump" - Bill Nye "Water Cycle Jump" - Bill Nye  Introduce/review the Water Cycle by reading pgs and answering the “Check Your Learning” questions. › If more time is needed, check MyClass to find the link to access the textbook pages.

1. Look at Figure 2. Where can you find each of the three states of water? › Solid – mountain glaciers, ice sheets, polar icecap, snow › Liquid - surface water, groundwater, surface runoff, precipitation › Gas - water vapour

2. Describe the water cycle. Draw your own labelled diagram.  Runoff is liquid water from melted snow and rain. The runoff water flows downhill to rivers, lakes etc. (surface water)  Some liquid seeps into the ground called groundwater (not below bedrock). This saturated area is called aquifer, with the top being the water table  Surface water evaporates, and snow/ice sublime to form water vapour *** Melting, evaporation, and sublimation are a result of increasing thermal energy of water particles.

2. Describe the water cycle. Draw your own labelled diagram.  Once in the atmosphere, water vapour cools and condenses into a liquid and form ice crystals (deposition). These form clouds.  Once large enough, the liquid drops fall as rain, and the ice crystals fall as snowflakes (precipitation) *** Condensation, deposition, and freezing are a result of cooling thermal energy of water particles.

3. Briefly describe how solid and liquid water may be converted to water vapour.  The sun provides the energy for evaporation and sublimation. It increases the thermal energy of water particles. Because of this, surface water evaporates and snow and ice sublime from Earth’s surface to become water vapour.

4. Describe how water vapour changes into solid and liquid water above Earth’s surface.  The low temperatures in the atmosphere cause a decrease in the thermal energy of water particles. As a result, the vapour either condenses into liquid, or undergo deposition to form ice crystals.

5. Does all surface runoff move directly into rivers, lakes, and oceans? Explain.  No, because Some liquid seeps into the ground called groundwater (not below bedrock). This saturated area is called aquifer, with the top being the water table

 Match the vocab words in the envelope with the correct definition.  You cannot use your notes for help, but you may use this diagram...

 The total amount of water on Earth remains constant.  The water cycle is a continuous pattern, in which water changes states and moves from one location to another.  The Sun provides the energy to drive the water cycle.  Processes of the water cycle involve the increasing or decreasing of thermal energy.
