Lesson 6 Vocab
air that is moving from a region of higher pressure to a region of lower pressure
Wind
water located underground that fills pore spaces in soil and rock layers
Groundwater
a huge volume of air that has a uniform temperature and humidity at a given altitude
Air Mass
a winter storm that lasts for at least three hours with winds greater than 56 km/h and large amounts of blowing snow
Blizzard
12x=48
x=4
the elevation of the land surface where the atmosphere meets the ocean
Sea Level
the movement of water through the Earth system
The Water Cycle
a weather front in which a cold air mass advances to replace a warm air mass
Cold Front
a period of unusually hot, and often more humid, weather than is typical for a region
Heat Wave
Simplify 12b+3a + 4 + 4b +2a
16b +5a + 4
the weight of the air pushing down on an area; the force exerted over an area by all of the air above that area
Atmospheric Pressure
solid or liquid water that falls from clouds to the ground
Precipitation
an area within the atmosphere where air is sinking and winds blow away from the center
High Pressure System
a huge, rotating, low pressure storm system that forms over warm water near the equator and has sustained wind speeds of 119 km/h or higher
Hurricane
10/x= 5
x=2
a property of matter that is equal to the amount of mass in a certain volume of matter
Density
the evaporation of water from the leaves of plants
Transpiration
an area within the atmosphere where air is rising and winds blow toward the center
Low Pressure System
a rotating column of air with extremely high wind speeds of 117 km/h or higher that touches the ground
15/x + 2 =7
x=5
a tool used to measure atmospheric pressure
Barometer
the amount of water vapor in a given volume of air, usually expressed as grams per cubic meter (g/m3)
Absolute Humidity
a boundary between a cold air mass and a warm air mass that is not moving
Stationary Front
her such as blizzards, heat waves, severe thunderstorms, tornadoes, and hurricanes that can damage buildings or cause loss of life
Severe Weather
20x +10 = 100/2
x=2
