Unit 6

The study of Earth’s atmosphere.

Conditions in the atmosphere, including humidity, cloud cover, temperature, wind, and precipitation.

The general pattern of weather in a particular part of the world over a long period of time.

Layers of air surrounding Earth.

Form of oxygen that has three atoms in one molecule.

Display of light in sky, usually at high latitudes; formed where particles from the sun enter Earth’s atmosphere and magnetic field.

Effect that Earth’s rotation has on the path of air and water moving at or above its surface, causing the fluid’s path to curve.

Narrow stream of high speed wind high in the atmosphere, generally moving west to east in the Northern Hemisphere.

A large body of air that has about the same temperature and humidity throughout it.

An instrument used to measure changes in air pressure.

Instrument used to measure wind speed.

Sinking air moves away from the system’s center when it reaches Earth’s surface.

Air rises when air from outside the system replaces the rising air, this air spirals inward toward the center and then upward.

Place where two air masses of different temperatures and pressures meet.

Cycle in which water moves through the environment, through the process of evaporation, condensation, and precipitation.

Water falling from clouds in any form, such as snow, ice , raindrops, or drizzle.

The use of reflected radio waves to determine the distance of an object and the direction it’s moving.

Change of matter from a liquid state to a gaseous state.

Small particle in the atmosphere around which cloud droplets can form.

Loss of water through a plant’s leaves.

Movement of the air caused by differences in air pressure.

A sudden spark, or energy discharge, caused when electrical charges jump between parts of a cloud between a cloud and the group.

Amount of water vapor in the air.

Amount of water vapor in the air compares to the amount in saturated air at the same temperature, reported as a percent.
