Water Cycle
Water falls to the Earth as rain, snow, etc.
Precipitation
Water is attracted to water
Cohesion
A measure of the amount of matter in an object
Mass
The percentage of Earth that is covered in water
70%
Water vapor cools and changes from gas to liquid
Condensation
Universal solvent
Amount of space occupied by an object
Volume
Percentage of water on Earth that is from glaciers
2%
Water molecules on Earth’s surface are heated by the sun and change from liquid to gas
Evaporation
“Stickiness” of water
Surface tension
A physical substance that occupies space
Matter
Percentage of water on Earth that is from salt water
97%
Water soaks into the ground and moves downward
Percolation
Water is attracted to other substances
Adhesion
Amount of mass in a specified space
Density
Percentage of water on Earth that is fresh water
1%
Water flows on Earth’s surface rather than soaking into the ground
Surface runoff
Freezing Point/Boiling Point in degrees Celsius
FP=0 degrees Celsius
BP=212 degrees Celsius
Density formula
Density=Mass/Volume
Arrange the density of the states of matter in order from least to most dense
Gas, liquid, solid
