Weather Vocabulary 1

a body of air that has about the same temperature and humidity throughout

• Air mass

• Air pressure

• Atmosphere

• Cold Front

Tags

NGSS.MS-ESS2-5

a measure of the weight of the atmosphere on a given area of the surface of the Earth; barometric pressure

• Air mass

• air pressure

• atmosphere

• cold front

Tags

NGSS.MS-ESS2-5

a blanket of mixed gases that are held to the Earth by gravity; the most dense gases are near the surface of the Earth

• convection current

• air pressure

• atmosphere

• cold front

Tags

NGSS.MS-ESS2-6

the leading frontal edge boundary of an advancing air mass that replaces warmer air and has colder air behind the boundary; indicated on a weather map by a line with blue triangles

• Atmosphere

• Cold front

• convection current

• Coriolis effect

Tags

NGSS.MS-ESS2-5

when temperature differences cause liquids and gases (fluids) to expand and move; the less dense areas continually rise, and the more dense areas continually sink creating a cyclical current

• atmosphere

• cold front

• convection current

• Coriolis effect

NGSS.MS-ESS2-4

the effect of the Earth’s rotation on the path of air and water; causes the path to curve

• High pressure

• Humidity

• Low Pressure

• Coriolis effect

Tags

NGSS.MS-ESS2-6

a region where the atmospheric pressure at the surface of the planet is greater than its surrounding environment; symbolized by an H on a weather map; generally means nice weather; rotates in a clockwise direction

• Humidity

• Warm Front

• High Pressure

• Low Pressure
