Water Systems Study Notes
The Water Cycle EVAPORATION: When the sun heats up the liquid in oceans and lakes and converts it to a vapour or steam CONDENSATION: When the vapour/steam turns into a liquid, forming little water droplets that then turn into clouds PRECIPITATION: Any form of water that falls onto the Earth's surface. This includes hail, sleet, snow, and rain INFILTRATION: When water on the ground surface enters soil SURFACE RUNOFF: Overland flow of excess water Water and Climate Warm Currents start at the equator, where the suns heat is the most intense. These currents effect the climate, and sea life. Warm currents effect climate by transferring their heat into the atmosphere, heating up the air. Water has a very high specific heat capacity . It takes a longer time to heat up than rocks. The Gulf Stream, starts at the Caribbean sea and flows north. Then, the stream turns northeast, crossing the Atlantic Ocean. That carries warm water to Iceland, Britain, and the surrounding areas. Water Distribution 97% of the world's water is too salty to use. 3% is freshwater, but is locked up in icecaps and glaciers Accessible freshwater only exists in lakes, river, and the atmosphere. Most of the Earth's water is found in oceans. Water is a limited resouece that we must conserve so that we don't run out. Water Treatment Steps 1. Intake water 2.Add chemicals into the water 3. Coagulation and Flocaulation. (When you clump all the dirt particles together to clean the water 4. Sedimentation 5. Filtration (when you filter the water of course) 6. Add chlorine into the water 7. Storage. (store water in those big tanks) 8. Distribute the water Watersheds A watershed is an area of land where the water eventually drains into one area of water body, like a stream, river, lake, or ocean. DID YOU KNOW THAT........ The oceans account for more than 97% of the world's total water? A river within an ocean is known as a current? Most of the freshwater in Earth is found in icecaps and glaciers? As the distance from a large body of water decreases, the amount of precipitation decreases, and the number of frost-free days per year increases? Warm ocean currents travel north? NOW YOU KNOW!!!! A water drop A storage tank The atmospher (for those of us who don't know) An Ocean The Water Cycle The Gulf Stream A Watershed Icecaps/Glaciers About 3.3 million people die every year from lack of clean water? Women in Africa walk an average of 5 miles to get water that isn't even that clean? All pictures come from google images (www.google.ca/imghp) THANKS FOR WATCHING!!!!!! 1.Choose outdoor landscaping appropriate for your climate. Native plants and grasses that thrive on natural rainfall only are best.

2.Install low-flow showerheads and faucet aerators. Because you’re saving hot water, you’ll also reduce your energy bill.

3.If you’re in the market for a toilet, buy a low-volume, ultra low-volume, or dual-flush model. 4.Fix leaky faucets. All those wasted drops add up—sometimes to 10-25 gallons a day. 5.Run your dishwasher and washing machine only when full. When it’s time to replace them, buy a water- and energy-efficient model. Remember, saving water saves energy, and saving energy saves water. 6.Eat a bit less meat, especially beef. A typical hamburger can take 630 gallons to produce. 7. Buy less stuff. Everything takes water to make. So if we buy less, we shrink our water footprint.
8.Recycle plastics, glass, metals, and paper. Buy re-usable products rather than throw-aways, as it takes water to make most everything.
9.Turn off the tap while brushing your teeth and washing the dishes. Shave a minute or two off your shower time. Millions of people doing even the little things makes a difference.

10.Know the source of your drinking water—the river, lake, or aquifer that supplies your home. Once you know it, you’ll care about it. You just won’t want to waste water. 10 ways to conserve water Water in most lakes comes from precipitation?
