71% Water, 29% Land
The amount of water that covers the earthvs amount of land.
TERM 2
Outgrassing
DEFINITION 2
The process by which water vapor and water emerge from
the layers deep within and below the crust
TERM 3
Eustasy
DEFINITION 3
Refers to the global sea level condition.
TERM 4
2.78% Freshwater
DEFINITION 4
Refers to the amount of freshwater on earth, which comes
from lakes, rivers, and streams.
TERM 5
Sublimation
DEFINITION 5
Refers to the direct change from ice to water vapor or water
vapor to ice.
Deposition
Water vapor that attaches directly to an ice crystal
TERM 7
Latent Heat
DEFINITION 7
The heat involved in the phase change of water and is hidden
within the structure of water.
TERM 8
Humidity
DEFINITION 8
The water vapor in the air.
TERM 9
Relative humidity
DEFINITION 9
A ratio expressed as a percentage of the amount of water
vapor that is actually in the air compared to the maximum
water vapor possible in the air at a d=given temp.
TERM 10
Saturation
DEFINITION 10
Happens when air is at 100% relative humidity, when the
rate of evaporation and the rate of condensation--the net
transfer of water molecules--reach equilibrium.
Adiabatic
The warming and cooling rates for a parcel of expanding or
compressing air.
TERM 17
Moist Adiabatic Rate (MAR)
DEFINITION 17
Rate at which an ascending air parcel that is moist, or
saturated, cools by expansion.
TERM 18
Cloud
DEFINITION 18
An aggregation of tiny moisture droplets and ice crystals that
ar suspended in air, great enough in volume and
concentration to be visible.
TERM 19
Stratus Clouds
DEFINITION 19
Appear dull, grey, and featureless Clouds.
TERM 20
Nimbostratus Clouds
DEFINITION 20
Yield precipitation and their showers typically fall as drizzling
rain.
Cumulous Clouds
Appear bright and puffy, cottonball clouds. They do not cover
the sky, the float in infinite varied shapes.
TERM 22
Stratocumulous Clouds
DEFINITION 22
Patches of lumpy, grayish, low-level clouds
TERM 23
Altocumulous Clouds
DEFINITION 23
represent a broad category of clouds. Occurs in many
different styles: patchy rows,wave patterns.
TERM 24
Cumulonimbus Clouds
DEFINITION 24
Towering giant clouds are thunderheads because of their
shape.
TERM 25
Fog
DEFINITION 25
Cloud layer on the ground, with visibility restricted to less
than 3300 ft. The presence of it tells us the air temp and the
dew point temp at ground level are nearly identical indicating
saturated conditions.
Weather
Referred to as the short-term, day-to-day condition of the
atmosphere, contrasted with climate.
TERM 32
Continental Polar (cP)
DEFINITION 32
Air masses form only in the Northern Hemisphere and are
most developed in winter and cold weather conditions. (Cool,
dry, moderately stable--Summer) (Cold dry, stable, and high
pressure--Winter)
TERM 33
Maritime Polar (mP)
DEFINITION 33
Exist over the northern oceans. (Cool, moist, unstable
conditions)
TERM 34
Maritime Tropical (mT)
DEFINITION 34
Warm, humid, stable to conditionally unstable. Comes from
the East and Midwest.
TERM 35
Convergent lifting
DEFINITION 35
Air flows toward an area of low pressure.
Convectional Lifting
air is stimulated by local surface heating.
TERM 37
Orographic lifting
DEFINITION 37
air is forced over a barrier such as a mountain range.
TERM 38
Frontal lifting
DEFINITION 38
air is displaced upward along the leading edges of
contrasting air masses
TERM 39
Windward Slope
DEFINITION 39
The wetter intercepting slope.
TERM 40
Leeward Slope
DEFINITION 40
The drier, far-side slope.
Stationary Front
When there is a stalemate between warmer and cooler air
masses where air flow on either side is almost parallel to the
front, although in opposite directions.
TERM 47
Lightening
DEFINITION 47
Refers to the buildup of electrical energy polarity between
areas within a cumulonimbus cloud.
