Transcript Weather and Water

EVAPORATION
The process in which liquid
water becomes water
vapor
HUMIDITY
The water vapor in the air
RELATIVE HUMIDITY
The amount of water vapor
in the air compared to the
amount of water vapor
needed to saturate the air
at a give temperature;
expressed as a
percentage
CONDENSATION
The process in which water
vapor becomes liquid
water
CONDENSATION NUCLEUS
A small particle on which
water vapor condenses
CLOUD
A visible accumulation of
water on condensation
nuclei, either as liquid or
ice, usually high in the air
PRECIPITATION
Any form of water that falls
from the sky/clouds
RAIN
Liquid form of
precipitation. It stays
liquid from beginning to
end.
SLEET
Precipitation that starts out
as a liquid but freezes on
the way down from the
cloud to the Earth.
HAIL
Precipitation in the form of
balls of ice. Freezes in
the clouds
FREEZING RAIN
Liquid precipitation that
freezes on contact once it
has landed on surfaces
on Earth (Cars, trees,
grass, concrete)

RUN OFF
When rain lands or snow melts
and the water flows, it carries
with it anything it touches.
For example:
-Oil from shingles on the house
-Fertilizers
-Dirt/sand
PHOTOSYNTHESIS
A process used by plants
to convert water, carbon
dioxide, and sunlight into
carbohydrates and
oxygen.
TRANSPIRATION
The release of water from
plants as a product of
photosynthesis.
TEMPERATURE
A measure of kinetic
energy of the molecules
of a material or
substance.
THERMOMETER
An instrument to measure
temperature
DEW POINT
The temperature at which a
volume of air is saturated
with water vapor;
condensation occurs when
the temperature drops
below the dew point.
DEW
Water that condenses on
surfaces when the
temperature drops below
the dew point.
FROST
Frozen dew. This occurs
when the dew point is
o
o
below 0 C (32 F)
