EVAPORATIONThe process in which liquid water becomes water vapor
HUMIDITYThe water vapor in the air
RELATIVE HUMIDITYThe 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
CONDENSATIONThe process in which water vapor becomes liquid water
CONDENSATION NUCLEUS
A small particle on which water vapor condenses
CLOUDA visible accumulation of water on condensation nuclei, either as liquid or ice, usually high in the air
PRECIPITATIONAny form of water that falls from the sky/clouds
RAINLiquid form of precipitation. It stays liquid from beginning to end.
SLEETPrecipitation that starts out as a liquid but freezes on the way down from the cloud to the Earth.
HAILPrecipitation in the form of balls of ice. Freezes in the clouds
FREEZING RAINLiquid precipitation that freezes on contact once it has landed on surfaces on Earth (Cars, trees, grass, concrete)

RUN OFFWhen 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
PHOTOSYNTHESISA process used by plants to convert water, carbon dioxide, and sunlight into carbohydrates and oxygen.
TRANSPIRATIONThe release of water from plants as a product of photosynthesis.
TEMPERATUREA measure of kinetic energy of the molecules of a material or substance.
THERMOMETERAn instrument to measure temperature
DEW POINTThe temperature at which a volume of air is saturated with water vapor; condensation occurs when the temperature drops below the dew point.
DEWWater that condenses on surfaces when the temperature drops below the dew point.
FROSTFrozen dew. This occurs when the dew point is below 0

What is weather?
WEATHER• The state of the atmosphere at
a given time• A description of the weather
includes observations and measurements of temperature, precipitation, air pressure and cloud cover.
• Weather changes from day to day and season to season
• Is our weather normal for this time of year?
CLIMATE• Weather conditions over a
long time.• Climate helps to describe a
region• Climates change, but over
years or centuries not days
SEVERE WEATHER• Weather that is
dangerous or causes damage
• Name some types of severe weather
SEVERE WEATHER• Tornados• Hurricanes/Cyclones• Thunderstorms/floods• Blizzards• Dust storms
HURRICANES• Form over oceans• Water temperature of 27
degrees C (81 degrees F)• Low pressure• Cause damage due to
wind and water
METEOROLOGY• The study of Earth’s weather
• A person who studies weather is called a Meteorologist
• What do we call someone who studies the climate?
WEATHER TOOLS• Thermomete
r• Hygrometer• Wind Vain or
compass• Anemometer• Barometer• Visibility
• Temperature
• Humidity• Wind
direction• Wind
speed• Air
pressure• Fixed point
in the distance
TEMPERATURE
• Average kinetic energy• How hot/cold the air is
HUMIDITY
• The amount of water vapor in the air
WIND DIRECTION
• The direction the wind is coming from
WIND SPEED
• How fast the wind is blowing
AIR PRESSURE
• The force of air pushing in all directions
VISIBILITY
• The distance a person can see through the air.
OUR ATMOSPHERE• Permanent
Gases• 78%
Nitrogen• 20% Oxygen• And other
gases
• Variable Gases
• 0 – 7% Water Vapor
• 0.01 – 0.1 % Carbon Dioxide
• And other gases
ATMOSPHERE• Many Layers• Troposphere: • Closest layer• Where weather occurs
• Stratosphere:• 10-50 KM above Earth• Ozone layer• Jet Stream• Airplanes fly here
•
ATMOSPHERE CONTINUED• Thermosphere: • Least understood• Air is very thing• Region of the atmosphere
first heated by the Sun• Up to 1500 degrees C or
hotter• Ionosphere:• Large number of
electrically charged ions
ATMOSPHERE PART 3
• Exosphere: • Atoms and molecules
escape into space• 300-600 KM above
Earth
• What causes the seasons?
• What ways is heat transferred?
ConductionConvectionRadiation
CONDUCTION
• Transfer of heat energy by touching
CONVECTION
• The transfer of energy/heat though a fluid, like air
RADIATION
• The transfer of heat/energy from a single source such as the Sun.
AIR MASS
• A large body of air with uniform temperature and humidity.
• Air masses have distinct boundaries and can extend hundreds or thousands of KM over Earth’s surface
• Can reach up into the Troposphere
3 TYPES OF AIR MASSES
• Tropical• Warm air
• Polar• Cold air• Arctic• Extremely cold air
