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.
|
|

|
an aggregation of suspended water droplets and ice crystals, formed from rising warm, moist air.

|
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
|
|

|
As the radio gets smaller, speeds increase.
|
|

|
World Meteorological Organization
|
|
Where does weather occur?
|

|
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
|
|

|
Rayleigh waves (up and down) and Love waves (side to side)
|
|
Order of Layers
|

|
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.
|
|
