Humidity
The amount of water vapor in the air.
Relative Humidity
The ratio of the humidity and the amount of water vapor the air can hold.
Saturated
air that contains as much water vapor as possible.
dew
when the air's ability to hold water vapor decreases and water from the now-saturated air condenses on any available surface.
frost
When the dew point is at or below zero.
fog
when a large mass of air cools and reaches its dew point.
Clouds
an aggregation of suspended water droplets and ice crystals, formed from rising warm, moist air.
High Clouds
cirrus, cirrostratus and cirrocumulus
Middle Clouds
Alto Stratus and Altocumulus
Low Clouds
Stratus, Stratocumulus and Nimbostratus
Clouds having vertical development
cumulus and cumulonimbus
Cirrus
thin and wispy, mare's tail, fair weather.
Cirrocumulus
white puffs, mackarel sky.
Cirrostratus
thin and sheetlike, rain or snow.
Altostratus
bad weather
altocumulus
thunderstorms
stratus
light drizzle or mist.
nimbostratus
light to moderate rain or snow
stratocumulus
rain
cumulonimbus
thunderheads
cumulus
common clouds
Convectional Lifting
circulatory air movement
Orographic Lifting
Over an obstacle
Frontal Lifting
WHen two masses make contact
Cold Front
when a cold air masses pushes itself into a warm air mass.
Warm Front
when a warm air mass covers a cold air mass like a blanket.
Occluded Front
When a cold front overtakes a warm front
Stationary Front
Two fronts are at a stalemate.
Thunderstorms
convectional lifting begins it, particles of precip grow heavier and drop, and the falling rain creates a downdraft. With the updraft and downdraft, a storm cell is created.i
Tornadoes
As the radio gets smaller, speeds increase.
WMO
World Meteorological Organization
Where does weather occur?
Troposphere
Persistance Method
the continuity of a weather pattern
Trend Method
based on the trend of a weather pattern.
Analog Method
compares present features of weather with weather of the past.
Birth of a Star
a forming star is a protostar. In a nebula, neighbor particles attract and they combine to form a star.
Life of Stars
First main sequence star for 90% of their lives, then red giant or super giant, then white dwarf or , then black hole or black dwarf.
Death of Stars
more massive, shorter life. End is a black dwarf of Black Hole.
troposhpere
where weather occurs; commercial jets fly here. increases with height
Stratosphere
Holds the O Zone; decreases with height
Mesosphere
absorb very little UV radiation. increases with height
Thermosphere
absorbs a lot of UV radiation; decreases with height.
Driving forces of air forces
as warm air rises, it expands and cools; result of convection current is wind.
Pressure-gradient forces
the forces caused by changes in pressure
Pressure gradient
a difference in pressure between 2 different locations.
Coriolis Effect
The apparent deflection due to the rotation of the Earth.
Surface winds in Northern Hemisphere and Southern Hemisphere.
clockwise; counterclockwise.
Primary Waves
longitudinal (compress and expand; travel through any material
Secondary Waves
transversal Waves; cannot travel through liquid
Surface Waves
Rayleigh waves (up and down) and Love waves (side to side)
Order of Layers
Inner Core, Outer Core, Mantle and Crust.
Asthenosphere
plastic; thermal convection currents contribute to its gradual flow; below the lithosphere.
Lithosphere
situated on top of the asthenosphere; floats on top.
Theory of Continental Drift
the world used to be Pangea, and due to seafloor spreading, the continents are separating.
The Theory of Plate Tectonics
the Earth's outer shell, the lithophere, is divided into eight relativel large plates.
Folds
When a rock is subjected to compressive stress, it ripples and folds.
Faults
When compressive stress overcomes the strength of rock, the rock fractures in two parts.
Reverse Fault
compressional forces
Normal Fault
tension
Thrust Fault
low angle between fault plane and horizontal plane
Divergent
2 move apart
Convergent
Coverge
Transform
move parallel to eachother.
Ion
A charged atom
Coulomb
Unit of Charge
Newton
Force
Electric Field
a kind of aura that extends through space.
Electrical Potential Energy
the energy a charged pposesses by virtue of its location in an electric field.
Volt
Electrical Potential (1 J/C)
Ampere
Electric Current (volts/ohms)
Series Circuit
An electric circuit in which electical devices are conneced in such a way that the same voltage acts across each one and any single one completes the circuit independently of all the others.
Parallel Circuit
An electric Circuit in which electrical devices are connected in such a way that the same voltage acts across each one and any single one completes the circuit independently of all the others.
Impulse
Change in Momentum
electromagnetic spectrum
the classification of electromagnetic waves according to frequency
Momentum-Impulse
a=F/M
Joules
Energy; kg*msq./ssq.
Watt
Power; kg*msq./scu.
Ampere
current; c/s

Charge; kg*msq/ssq/c
Newton's First Law of Motion
law of inertia; an object at rest will stay at rest and an object at motion stays in motion.
Newton's Second Law of Motion
Acceleration is proportional to the net force divided by mass
Newton's Third Law of Motion
For every action there is an equal and opposite reaction.
Reverberations
multiple reflections.
Echo
the reflection of sound.
Acoustics
The study of sound properties.
