Water Budget and Water Cycle

Percentage of the world covered in water

71%

Of all the water on earth, the percent found in the ocean is

97%

Of all the freshwater how much is in glaciers and icecaps

3%

What percentage of water is potable

1.2%

Three limiting factors effecting distribution of water

Pollution, tempatures, and human activities

What type of chemical bond is formed between hydrogen and oxygen

Covalent

Which property allows for the dissolution of salts into water

Polarity

What percent of the sea water is made up of water molecules

96.5%

Which ocean contains the most ocean water by volume

Pacific Ocean

Process of cloud formation that occurs when molecules of water vapor come close enough together

Condensation

Process by which liquid water changes to a gas

Evaporation

Process of cloud formation that occurs when water is in the for, of moisture that fall to earth such as rain and snow

Precipitation

The continuous movement of water between the ocean, atmosphere, and land is called

The water cycle

Ocean water has a pH of

8

Water is referred to as the

Universal solvent

Based on the pH ocean water is

Slightly basic

At night when photosynthesis does not occur and respiration does occur,

During the day, when photosynthesis occurs, CO2 is taken out of the water causing the pH to increase making it basic, at night,when respiration occurs,CO2 is added to ocean water, causing the pH to decrease making it acidic.

About how much DO can ocean hold

1-12ppm

About how much DO can air hold

200ppm

What main physical factor affect the amount of DO ocean water can hold

Tempature

On average, the salinity of ocean water is

35 ppt
