geo quiz 4 Flashcards
definitions
equator
atmospheric heating
an imaginary horizontal line diving the Earth into a northern and southern hemisphere
axis
atmospheric heating
an imaginary line around which the Earth rotates
equinox
atmospheric heating
when Earth’s axis is perpendicularr to incoming solar radiation
occurs 2x a year in spring and fall
Summer Solstice
atmospheric heating
when the North Pole experiences 24 hours of daylight
during the Sun rays’ highest point
albedo
atmospheric heating
the portion of sunlight incidence/radiation that is reflected by a surface
evaporation
atmospheric heating
point at which water can only reach a certain temperature since molecules will start to break free
weather
weather
short-term changes in the atmosphere
climate
weather
describes what weather will be like over a long period of time in a specific area
the Coriolis Effect
weather
the effect the Earth’s rotation has on ocean currents, atmosphere, and air travel
water vapor capacity
weather
the max amount of water that can be stored in a given air mass at a certain temperature
moisture content
weather
how much water is in the air
relative humidity
weather
how much water vapor is in the air compared to the maximum amount possible
calculated by dividing the moisture content/ water vapor capacity
dew point
weather
the temperature when air becomes saturated
when water content equals capacity
saturation
weather
when air has reached maximum water capacity
precipitation
weather
process when water condenses into liquid droplets when air reaches 100% humidity
adiabatic
weather
a temperature change resulting from changes in pressure alone
Polar cell
weather
the circulation cell that forms between approx. 90-60 degrees North of the equator
