14A. The Water We Drink (Make sure you have this
copied).
- 1. Earths ocean covers more than 140 million
square miles. - 2. The Earths oceans contain about 97 of all
the water on Earth. - 3. 99 of the total water supply is unsafe to
drink. - 4. Earths water cycle continuously replaces the
supply of fresh water. - 5. Most of the water humans use every day, about
80 of it, comes from surface water in freshwater
rivers and lakes.

17 Streams
- Streams are bodies of water that flow over land
- Streams start in the high grounds such as hills
and mountains. - Streams are often formed by melted snowfields and
glaciers, or overflowing lakes. - Streams empty into larger water bodies through
parts called mouths.
18Rivers
- Rivers are mostly formed by wide streams or many
streams joining together called tributaries. - Rivers are found on every continent of Earth
except Antarctica. - The largest river is the Nile in Africa. It is
4,160 miles long. - The Amazon is the largest river system.
- Rivers carry away water from land.
- Many of the worlds first settlements and
civilizations developed along rivers. - Rivers are a valuable source of energy.
- Rivers are important for trade and transportation.
19Lakes
- The word lake means hole
- Lakes are created when water fills a hole or
opening in Earths surface. - Lakes exist on every continent except Antarctica.
- The greatest number of lakes are found in North
America and northern Europe. - Lake Baikal is the largest lake in the world
- North America has the most lakes in the world.
The Great Lakes are the largest. - Lakes can be made by humans who build dams to
control rivers. They are called reservoirs.
20Ocean
- Oceans cover much of the planet. (75)
- The largest is the Pacific, then the Atlantic,
Indian and Arctic. - The Pacific is also the deepest.
- Oceans have mountain ranges, plains, basins, and
valleys. - Iceland is formed from a mountain in the
Atlantic. - Ocean currents are caused by winds. They move
clockwise in the Northern Hemisphere and
counterclockwise in the Southern Hemisphere. - Ocean currents carry hot and warm water.
- The pull of the sun and the moon cause tides.
- Smaller bodies of water connected to oceans are
called gulfs, bays, and seas.
