Water Cycle

http://www.mbgnet.net/fresh/cycle/index.htm
1. Define "water cycle".
A complex process that not only gives us water to drink, fish to eat, but also weather patterns that help grow our crops. Contains precipitation, evaporation, and transpiration.

2. What fraction of the Earth’s surface is covered in water? 
The fraction of Earth's surface that is covered in water is 3/4.

3. What percentage of all the Earth’s water is in a form that is useable to humans and land 
animals?
The percentage of all the Earth's water that is in a form that is useable to humans and land animals is 1%.
http://www.mbgnet.net/fresh/cycle/concepts.htm

1. Evaporation is the process where a liquid changes from its liquid state to a 
 state. 
2. Why is evaporated water so clean?  Evaporated water is so clean because during the process of evaporation, impurities in water are left behind.

3. Condensation occurs when a  is changed into a liquid.

4. Condensation is the opposite of  evaporation.

5. When the temperature and atmospheric pressure are right, the small droplets of water in clouds form larger droplets and precipitation occurs.

6. Define transpiration: the passage of gases through fine tubes because of differences in pressure or temperature.


7. Define percolation: the slow passage of a liquid through a filtering medium.

1. Using the terms "evaporation", "condensation", and "precipitation", explain the water 
cycle in your own words. 
The cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

2. What factor is most important in determining whether water is a solid, liquid, or gas? 
The factor that is most important in determining whether water is a solid, liquid, or gas is temperature.

3. Is the amount of water on Earth always changing or is it a constant amount? 
The amount of water on Earth is always changing, but it is a constant amount.
