1. Water on Earth
Where does Earth’s water come from? Hydrogen (from the Big Bang – formation of the Universe) + Oxygen (supernovae “aka Exploding Star”) = Water Molecule = +

3. Water Cycle
What drives the water cycle? Thermal energy from the sun causes phase changes in the water cycle

4. Water Cycle

5. Water Cycle
Evaporation Heat energy from sun evaporates (liquid to gas) of both oceans and lakes

6. Water Cycle
Condensation Water vapor (gas) cools to a liquid and attaches onto particulate matter (dust, pollution) and generates clouds

7. Water Cycle
Precipitation Clouds contain liquid. When it is too heavy to carry, it falls to the ground as precipitation. Forms of precipitation: Snow, sleet, freezing rain, rain, hail.

8. Water Cycle
Runoff Runoff is the result of gravity causing water to return to lakes and ocean
