A. The Water We Drink (Make sure you have this copied). 1. Earth’s ocean covers more than 140 million square

miles.

2. The Earth’s oceans contain about 97% of all the water on Earth.

3. 99% of the total water supply is unsafe to drink.

4. Earth’s 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.

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.

Rivers 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 world’s first settlements and civilizations

developed along rivers. Rivers are a valuable source of energy. Rivers are important for trade and transportation.

Lakes The word “lake” means “hole” Lakes are created when water fills a hole or opening

in Earth’s 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.

Ocean 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.
