groundwater
Water that fills the cracks and spaces in underground soil and rock layers
water cycle
The continuous process by which water moves from Earth's surface to the atmosphere and back driven from energy that comes from the sun
evaporation
The process by which molecules at the surface of a liquid absorb enough energy to a gaseous state.
humidity
The amount of water vapor in the air.
climate
The pattern of temperature and precipitation typical of an area over a long period of time
Gulf Stream
A large, powerful warm surface current in the Atlantic Ocean that affects the climate of land in its path
Sun
The water cycle is driven by energy from this.
Nitrogen
The gas that makes up about 78% of the atmosphere.
Oxygen
The gas that makes up about 21% of the atmosphere.
Barometer
An instrument used to measure air pressure
Troposphere
The layer closest to Earth, where almost all weather occurs; the thinnest layer
Stratosphere
The layer of the atmosphere that contains the ozone layer.
Mesosphere
The atmospheric layer between the stratosphere and the thermosphere.
Thermosphere
The uppermost layer of the atmosphere, in which temperature increases as altitude increases.
radiation
The direct transfer of energy by electromagnetic waves.
Coriolis Effect
The way Earth's rotation makes winds in the Northern Hemisphere curve to the right and winds in the Southern Hemisphere curve to the left.
Cumulus
Clouds that look like cotton and form less than 2 km above the ground.
dew point
The temperature at which condensation begins.
Maritime Tropical
A warm, moist air mass that is formed over the ocean in tropical areas.
Continental Tropical
A warm, dry air mass that forms over land in tropical regions.
Maritime Polar
A cold, moist air mass that is formed over the ocean in polar areas.
Continental Polar
A cold, dry air mass that forms over land in polar regions.
Jet Streams
Narrow bands of high-speed winds that circle the earth, blowing from west to east.
Air Mass
A huge body of air that has similar temperature, humidity, and air pressure at any given height.
Cyclone
A swirling center of low air pressure
Temperate Zone
The area between the tropical and polar zones, from about 23.5 degrees to 66.5 degrees north and 23.5 degrees to 66.5 degrees south latitudes.
monsoons
Sea and land breezes over a large region that change direction with the seasons.
Stationary Front
When a warm air mass and a cold air mass meet and no movement occurs.
Current
A large stream of moving water that flows through the oceans.
Air pressure
The measure of the force with which air molecules push on a surface. As you rise up in the atmosphere, air pressure decreases.
