Name and describe the different types of fronts.
Warm fronts is when warm air is moving in, cold fronts is when cold air is moving in. Stationary fronts are not moving and the winds blow parallel to the front but in opposite directions on opposite sides of the front. Occluded fronts are when a cold air mass overtakes a warm air mass.

Describe the different classes of air masses.
Maritime tropical forms over water and is warm and wet. Continental tropical forms over land and is warm and wet. Maritime polar forms over water and is cold and wet. Continental polar forms over land and is dry and wet. (continental polar creates lake effect snows).

Describe the difference between fusion and fission.
Fusion is the smashing together of molecules to release energy, and Fission is the splitting apart of atoms to release energy.

Describe the difference between bioaccumulation and biomagnification.
Bioaccumulation is the build up of toxins in an organism, and biomagnification is the increase of toxins at higher levels of the food chain.

Describe the difference between humidity and relative humidity.
Humidity is the amount of water in the air, relative humidity is the amount of water in the air compared to how much the air can hold. (Percent of saturation)

Describe the difference between El Nino and La Nina
El Nino is a strong low pressure system reversing winds and increasing precipitation, creating flooding rains. La Nina is when conditions go back to normal but are more intense.

Name and describe two of the three motions the solar system undergoes.
Precession is the wobble of earth's axis, Nutation is the slight change in angle of earth's tilt that occurs every 18 years, Barycenter has to do with one body revolving around another and the pull that these bodies have on each other.
