Biosphere Ecology (113 cards)
_______________ focuses on the entire habitable portion of plant earth
biosphere ecology
biosphere ecology focuses on two things
-global climate patterns
biome distribution
weather pertains to the __________________ of temperature, precipitation, wind speed, ect
current conditions
climate represents a _____________ term description of weather. It is based on averages, variations, extremes, and timing measured over centuries
long term
______________ is the ultimate global source of energy that drives global climate
the sun
its energy is not recieve equally all over earth
near the equator the sun rays strike earths surface ______________________
perpendicularly
toward the poles, the sun’s rays are spread over a ______________________ and take _____________ through the atmosphere
larger area and longer path
solar radiation heats _________________ which warms air above it
earths surface
_____________ is a term to describe that when warm air is less dense than cool air so it rises
uplift
uplift explains __________________________
air pressure decreases with altitude
_____________ air hold less water vapor than _____________ air
cool
warm
as rising air expands and cools, ______________ to form clouds
water vapor condense to form precipitation
___________ recieve the most solar radiation so they have the most precipitiation
tropical regions
uplift of air in tropics results in ___________________
low atmospheric pressure zone
when air reaches its maximum altitude, the air flows north or south toward _________________ where it is ________________
poles
cooled
_______________ the air descends when it cools forming high pressure zones at 30n and 30s.
subsidence
high pressure zone correspond to _______________________
lack of precipitation
major deserts are often high pressure zones
_____________ is the large scale pattern of atmospheric circulation that occurs between o-30
hadley cell
_______________ occurs near the north and south poles due to high pressure zone with little precipitation they are termed ______________
polar cell
polar deserts
the _______________ exists at mid-latitudes
ferrell cells
the three circulation cells
- hadley cell
- polar cell
- ferrell cell
the three circulation cells result in 3 climate zones
-tropical, temperate, polar
_________________ is defined as
objects at equator move east at 1040 mph
object north or south of equator move to east at 520 mph
coriolis effect
an air mass at the equator that flows toward the poles is moving faster than the ground below it appears to be deflected to the ______________
east
