What is Surface Tension?
The force between the molecules that creates tension specifically on the top layer of any volume of water.
What is Deposition (In Clouds)?
The change in state of matter (Phase Change) from gas to solid that occurs with cooling

What is Frontal Lifting?
A cold, dry air mass collides with a warm, moist air mass
Why is the density of solid water different from liquid water.
The molecules are ordered in a structure increasing volume, decreasing the density.
Explain Sublimation.
Process where ice changes into water vapor without first becoming liquid. Movement is up into the atmosphere.
