The document discusses the water cycle and different types of clouds and precipitation. It explains the water cycle as evaporation of water from oceans and rivers into water vapor, transpiration of water vapor from plants, condensation of water vapor back into liquid form, and precipitation of water falling back to earth. It then defines dew, fog, and the three main types of clouds - cirrus, stratus, and cumulus. Finally, it defines precipitation as moisture falling from the air to the ground and provides examples of rain, snow, and hail.
Weather and Stars
- 4. Evaporation Water from oceans and rivers changes to water vapor.
- 5. Transpiration Plants release water vapor through their leaves.
- 6. Condensation Water vapor goes back to liquid form.
- 7. Precipitation Water falls back to earth in the form of rain, hail or snow.
- 8. Collection Water comes back to earth’s water reserve.
- 9. Dew It is formed at night when the water vapor in the air condenses onto any exposed surfaces.
- 11. Cloud Is made of tiny water droplets. A visible mass of condensed water vapor floating in the atmosphere, typically high above the ground.
- 12. The Three Main Types of Clouds
- 13. Cirrus- it is curly, sometimes it looks like silk. Stratus- the word stratus means ‘to spread out’ in Latin. It forms a layer stretching across the sky. Cumulus-the word cumulus means ‘a heap’ in Latin. It is thick and puffy, flat bottoms. Shaped like hills.
- 14. Cirrus cloud
- 15. Stratus cloud
- 16. Cumulus cloud
- 17. Fog Fog is cloud near the ground. When the water vapor near the ground is cooled and condenses into tiny water droplets, fog is formed.
- 19. Precipitation Is moisture falling from the air to the ground.
- 20. Examples of Precipitation 1. Rain- water falling from the sky when the temperature is above 0 degrees C. 2. Snow- is formed when the temperature is below freezing point of water. 3. Hail- falls in the form of lumps of ice. It happens in summer.
