Saltwater Salt water is 97% of all water on earth. All of

this water is in our oceans. As the name implies, salt water contains a lot of sodium, or salt. However when it evaporates, the salt is left behind.

Saltwater (continued) Saltwater is undrinkable. If you drink it, you

actually become dehydrated faster. Also it’s said drinking saltwater makes you

crazy! however, Saltwater helps heal cuts and

bruises

Fresh water Fresh water is a type of water without salt

we need for many things, but only 3% percent of earth’s water is fresh and a only 1% of that fresh water is usable. We get this water from lakes and streams.

Fresh Water (continued) We need fresh water for many reasons. We

need it to drink, shower, water plants, etc.

Water Cycle The water cycle is the cycle in which water

changes into the three stages of matter at least once: liquid and gas

Water Cycle The first step in the water cycle is

evaporation, in which the suns heat vaporizes* the water and it rises into the sky as a gas

* in Sci-fi movies, if some one vaporizes, he dematerializes and reappears elsewhere like so…

Water Cycle Step 2 of water cycle: This water vapor

cools and condenses into clouds. These clouds are full of water.

Water Cycle Step three of the water cycle: Precipitation*.

Remember those water filled clouds? When the clouds can’t hold the water anymore, they dump it, causing rain or snow depending on the temperature.

Ocean TopographyThe following graph shows all layers of the ocean. First is the continent. Then, the continental shelf, which generally means the beach. Farther out is the super steep and deep continental slope a few miles wide and deep.

Ocean Topography Once these slopes flatten out, they form

continental rises which are basically underwater plains. When tectonic plates meet underwater, they form mid ocean ridges.

Ocean TopographySea level is the top of the ocean water. So if I’m

6,000 feet above sea level, I hope I’m in a jet.

Currents and tides Tides are created by the gravitational field

between earth and the moon.

Currents and tides The moon travels in a ovalish circle around

earth. When it’s closer to earth, the tide comes in and waves become higher. When the moon is farther away, the tide goes out and waves die down.

Currents Currents are the direction that water flows

and at a certain speed.

Currents Currents are caused by a few things. it could

be that the river, lake, or ocean is on a slant, and it flows down it. It also could be strong wind.

Human’s effect on water Humans can dump harmful waste into the

water, killing fish and birds.

Human’s effect on water However, we do have programs that help

keep our water clean, such as Nickelodeon's Big Green Help.
