science Flashcards
wind is the
air parallel to earths surface
a wind vane
is helpful to know which way the wind is blowing
unequal heating and
earths rotation affect wind and weather conditions in land , local and global regions
winds that blow over short distance and affect local weather are called
local winds
the two types of local winds are
sea breeze and land breeze
a local wind that blows over an ocean or a lake
sea breeze
the flow of air from land to a body of water
land breeze
the patterns of winds moving around the globe
global winds
global winds form from
temperature differences between the equator and the poles
the way earths rotation makes winds curve is called the
corolis effect
global winds affect local weather by
moving masses of air from one place to another
the air masses affect the temperature
rainfall and air pressure
10km above earths surface are bands of high speed winds are called
jet streams
climate is the
long term weather
earths surface is divided into
three types of temperature zones
the three types of temperature zones
tropical , polar , temprate
climate is affected by
latitude altitude distance from large bodies of water
areas closer to the equator
have warmer climates
near earths surface
tempreture decreases as altitude increases
the main factors that affect the amount of precipitation an area receives
are prevailing , presence of mountains , and seasonal winds
the amount of water vapor an airmass carries
affects how much rain or snow it can produce
the presence of a mountain range can affect
the type and location of precipitation
scientists classify climates by taking into account an areas
average annual precipitation and the vegetation found growing there
gasses in the atmposhere called greenhouse gasses such asn
water vapor , carbon dioxide , methane , and nitrous oxide ,absorb much of the heat leaving earths surface
the greenhouse effect
trap heat keeping earth warm
climate change is
a sudden or gradual change in earths climate
how do scientists gather information about climate conditions million of years ago
by studying fossils , sediment in ice , and ocean cores, glaciers , tree rings and coral reefs
the color system consists of the
sun , planets , moons , a variety of smaller objects
one astronomical unit
150 000 000
the sun is a gaseous body
larger than anything in the solar system
chunks of rock
meteoroids
rocky bodies
asteroids
comets are
lose balls
the layers of the sun
convection , core , radiation
how many moons does mars have
