Water Cycle

100

A volume of air defined by its temperature and water vapor content.

Air Mass

100

The layer of gasses that surrounds the Earth and is held in place by gravity.

Atmosphere

100

The process of water going down into the soil and rock layers.

Infiltration

100

General weather over a long period in a given place.

Climate
200

Is the gaseous phase of water.

Water Vapor

200

When the cold air mass takes over the warm air mass, causing it to go up into the atmosphere.

Cold Front

200

The use of science and technology to predict the weather for a given location and time.

Weather Forecast

200

Is water located beneath the surface.

Groundwater Storage

200

Deflects winds caused by Earth’s rotation making winds appear to curve.

Coriolis Effect

300

The process by which a liquid turns into a gas.

Evaporation

300

Forms when a cold front or warm front stops moving and lingers over an area for an extended time.

Stationary Front

300

The amount of water vapor in the air.

Humidity

300

An underground body of rock, where the material contains water.

Aquifer

300

Forms when a warm air mass gets caught between two cold air masses.

Occluded Front

400

The process by which water vapor (water in its gas form) turns into liquid.

Condensation

400

The transition zone where a warm air mass is replacing a cold air mass.

Warm Front

400

Measures the distance north or south of the equator.

Measures distance east or west of the prime meridian.

Latitude

Longitude

400

Is the excess water that flows over land when the soil below it is flooded.

Surface Runoff
