  1. Hydrology:Water Cycle 8.E.1 Explain the structure of the hydrosphere including: Water distribution on earth Local river basin and water availability

  2. Warm-up 10/8 • How would you describe water to a visitor from another planet who has never seen it? (min. 30 words) • Remember to mention where it comes from, where to find it, how to use it, where it goes, etc.

  3. Water • Water is one of the most common substances on Earth. • Water never leaves the Earth. It is constantly being cycled through the atmosphere, ocean, and land. • This process, known as the water cycle, is driven by energy from the sun. The water cycle is crucial to the existence of life on our planet

  5. Evaporation • During part of the water cycle, the sun heats up liquid water and changes it to a gas by the process of evaporation. • Water that evaporates from Earth’s oceans, lakes, rivers, and moist soil rises up into the atmosphere.

  6. Transpiration • The process of evaporation from plants is called transpiration. • This usually takes place as water exits from plants leaves

  7. Condensation • As water (in the form of gas) rises higher in the atmosphere, it starts to cool and become a liquid again. • This process is called condensation. When a large amount of water vapor condenses, it results in the formation of clouds.

  8. Precipitation • When the water in the clouds gets too heavy, the water falls back to the earth. This is called precipitation. • Precipitation can form as rain, hail, sleet, or snow

  9. Runoff • When rain falls on the land, some of the water is absorbed into the ground forming pockets of water called groundwater. • Most groundwater eventually returns to the ocean. Other precipitation runs directly into streams or rivers. Water that collects in rivers, streams, and oceans is called runoff.

  10. Homework • Yellow – Ocean • White – Clouds • Black – groundwater • Brown – soil • Green – Glacier • Orange – Animal • Pink – River • Blue- Plants • Red – Lake

  11. Write a creative story from the perspective of a raindrop. • You must tell me each phase/ change you went through according to your water cycle voyage. • BE CREATIVE! • DUE WEDNESDAY
