What are the three main stages of the hydrologic cycle?
Evaporation, Condensation, Precipitation

"Some molecules in a water mass have attained sufficient kinetic energy to eject themselves from surface of water"
What step in water cycle does this chemical reaction describe?
Evaportation
100
Which inorganic reservoir makes the water taste salty?
Chloride
100

How does damming a river for hydroelectricity affect the water cycle?
It affects land use, homes, and natural habitats.
200
What is another step involving plants, not included in the main three?
Transpiration: is the evaporation of water through minute pores, or stomata, in the leaves of plants.
200
"---- may take place as soon as the air contains more water vapour than it can receive from a free water surface through evaporation at the prevailing temperature. This condition occurs as the consequence of either cooling or the mixing of air masses of different temperatures"
What step in Water cycle the chemical reaction describe?
Condensation

What are 2 organic reservoirs found in water?
Vegetarian roots-in water when they die, and Microorganisms
200
what is the "cloud Storage" also known as?
Condensation

Name a human advancement/technology that increases water availability.
digging wells to get at groundwater, collecting rainwater, and using desalination—salt removal—to get fresh water from the ocean
300
True or False: When water reaches the ground after transpiration, it is evaporated again into the water cycle.
False, water may penetrate Earth's surface and become ground water.
300
After being condensed, water vapour in the atmosphere is released to form -----.
Precipitation

Why is Fluoride important for the human body?
It is needed for proper development of our teeth and bones
300
how does water travel from air to land?
Precipitation
300
How does deforestation by humans effect the water cycle?
Deforestation reduces transpiration from plants and trees.
400
How does the sun affect the water cycle?
The sun and its factors (i.e. heat) affect evaporation.The rates of evaporation and precipitation depend on solar energy, as do the patterns of circulation of moisture in the air and currents in the ocean.

True or False: water is always represented in a chemical reaction as H20. Water is the only compound that exists as a solid, liquid, and gas.
True.
