The Water Cycle and Weather

1. The Water Cycle and Weather Mr. Leslie’s Science Class

2. Three States of Water • ¾ of Earth’s surface is covered by water. • Water is found on Earth in three forms: • Solid • Liquid • Gas

3. Liquid state • Streams • Lakes • Rivers

4. Solid state

5. Gas state Water vapor (you cannot see it)

6. Evaporation • Evaporation is the change of state from liquid to gas • Even on a cold day, heat from the Sun can make some water from a lake evaporate.

7. Condensation • Condensation is the change of state from gas to liquid. • When water vapor, is in the air, connects with cool air, the water vapor condenses back to liquid form.

8. Water Cycle • The water cycle is the movement of water into the air as water vapor and back to Earth’s surface as precipitation.

9. Precipitation • Is any form of water that falls from clouds to Earth’s surface Sleet or

10. Types of Clouds • Stratus • Cumulus • Cirrus • Cumulonimbus Cloud Website - NASA

11. Stratus Clouds • Stratus clouds are low-level clouds that form in layers. Stratus clouds usually bring rain.

12. Cumulus Clouds • Cumulus clouds are fluffy and have flat bases. They form low in the sky. They usually mean fair/good weather. • They look like animals!!!

13. Cirrus Clouds • Cirrus clouds are thin, feathery clouds made of ice crystals. They form high in the sky. Cirrus clouds indicate fair/good weather.

14. Cumulonimbus Clouds • Cumulonimbus clouds are normally the tallest clouds and bring thunderstorms.

16. Questions to answer • Tall clouds that produce thunderstorms are called? • What are the four types of precipitation? • What are the stages of the Water Cycle? • What is happening when you glass of water has drops of water running down the outside of your glass? • What are the three states of water?
