Keep going! Check out the next lesson and practice what you’re learning:

How water cycles on Earth.

Ecology on Khan Academy: Why are polar bears found only in the Arctic? Why does mildew grow in your shower and not (hopefully) in your sock drawer? Learn how ecologists study the interactions between organisms and their environment, and how these interactions affect where, and in what numbers, different types of organisms are found.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

Summary for my online learning gang:
The first step of water cycle is evaporation. It is when water gets transformed into a gassy state. This is state of water is called water vapor. The water vapor then rises with the air, which has been heated, and condenses into small droplets, which then forms clouds, this is called condensation. Sometimes they can form ice crystals too. When the droplets get heavy enough they precipitate in a process called precipitation. They fall to the ground, mountains, oceans, and many other places. When the droplets hit mountains, sometimes turning into snow, they melt and run down the mountain, sometimes forming rivers. This process is called surface runoff. If the water falls into the soil, it goes into the ground and becomes groundwater. Lakes form when the ground is already full of water so water begins to form on the surface. Plants take up water from the ground and transports it through its leaves. Still though, a lot of the water will transpire out. Transpiration is evaporation out of the leaves of the tree. Water is stored in many places but fresh water can be stored in glaciers and permanent snow cover. Also groundwater, which can be accessed through wells.

Hello, could you do a water treatment math video(s)? This is an area that ADULTS struggle in passing on the state tests. In the college I attended, even the Math center at the community college apologized for not being able to help out. You will be helping so many water / wastewater operators in various states who struggle with math. PLEASE consider doing this. The impact is far reaching in this field. EI pressure (psi) and elevation, detention time in basins both circle and square. chemical dosing (lots of chemicals). John - Water treatment operator
