Product and Energy Flow:
--High evaporation rate around the equator, more than the Polar Regions because air rises
--At the equator, sunset/sunrise never changes—Alaska has very long summer days
--Belts and cells of air circulation about a rotating earth: polar cell, ferrel cell, Hadley
cell, equatorial cell, subtropical high, polar easterlies, westerlies, southeast tradewinds,
northeast tradewinds, westerlies, polar easterlies.
--Ocean currents of the world: can create El Niño for California with Mexico subtropical
currents overriding the Alaska currents from the north
--Water that hits the east of the US is a gulf stream moving from south to north that
warms the water
--last 4 million years…approx. 22 glacier periods (ave. temp decreased 4-10 degrees
--10,000 years ago.
..about 6 million people existed…beginning of agriculture
--climate has had a big impact on the development of humans
--terraces…ocean stopped, and eroded a platform (175 meter below)
--El Niño southern oscillation (ENSO) comes every 3-7 years, can be strong or weak
-it leads to many marine life dead because water temp. increases 7-8 degrees Celsius
--La Niña may follow El Niño…effects are the opposite and can lead to drought, La
Nina’s are relatively weaker
--Coal, oil, natural gas are fossil fuels…when you burn, you produce carbon dioxide CO
(heats up the earth with solar energy)
--water vapor traps the largest amount of heat
--nitrogen oxides (N
O) also produce heat
--methane gas (CH
) too that comes from cattle
--Really rapid change in temps., but generally are slow
--Deserts typically have lots of sun, with little cloud cover…therefore heat radiations
back up to the atmosphere, which makes it really cold in the night.
..average temp change
from day to night is 40 degrees F.
Largest is 100 degrees F.
--General upwelling in the equatorial area, but it takes a long time as it moves up very
