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

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.
Transpiration
▪ The process of evaporation from plants is called transpiration.
▪ This usually takes place as water exits from plants leaves
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.
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
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.
Homework
▪ Yellow – Ocean
▪ White – Clouds
▪ Black – groundwater
▪ Brown – soil
▪ Green – Glacier
▪ Orange – Animal
▪ Pink – River
▪ Blue- Plants
▪ Red – Lake
▪ 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!
