Where’s The Water

Did you know...?

• 80 percent of the earth's surface is water

• 97 percent of the earth's water is seawater.

• 2 percent of the earth's water supply is locked in icecaps and glaciers.

• 1 percent of the earth's water is available for drinking.

• About 60 percent of the weight of the human body is water.

• An elephant is 70 percent water.

• A tomato is 95 percent water.

Physical Facts

Did you know...?

• At sea-level pure water freezes into ice at 32 F (0 C)

• At sea-level pure water boils into steam at 212 F (100 C).

• Seawater freezes at about 28 F (-2 C)

• A cubic foot of water weighs 62.4 pounds.

• A gallon (231 cubic inches) of water weighs about 8 1/3 pounds.

• Seawater is usually about 3 1/2 percent heavier than fresh water because it contains about 35 pounds of salts in each 1,000 pounds of water.

• The pressure a mile down in the ocean is more than 2,300 pounds per square inch.

• Water expands by nearly one tenth of its volume when it freezes. 1 cubic foot of water becomes 1.09 cubic feet of ice.

• When a cubic foot of water at sea-level pressure boils away, it becomes about 1,700 cubic feet of steam.

The Water Cycle

Did you know...?

• The water we use today is the same water the dinosaurs used.

• A fully grown oak tree may transpire about 100 gallons (380 liters) of water a day. In summer an acre of corn transpires from 3,000 to 4,000 gallons (11,360 to 15,140 liters) of water each day.

• Once evaporated, a water molecule spends ten days in the air.

• Every 24 hours about 250 cubic miles of water evaporates from the sea and the land.
