geography lecture exam 2
compare the short term and long term carbon cycle
in the short term, carbon is stored in the atmosphere, oceans, and biosphere and it takes months to centuries to be recycled. the long term contains about 99 percent of total carbon found mainly in rocks and fossil fuels and can take millions of years to recycle.
extra credit question: what can we do about lessening the greenhouse enhancement?
lower emissions/ keep SLR and Tair at 2FT 2degrees celcius
sunspots effecting temperature: LOW: High:
lower sunspots= cooler climate/ less radiation higher sunspots= warmer climate/ more radiation

Biomass is plant or animal material used as fuel to produce electricity or heat.

Which quadrant is the weakest of a storm?
Back left
Milankovitch cycle

What are the GHG emissions
Co2, CH4, and N2O
What direction does a low pressure storm or cyclone move in the northern hemisphere?
Counter clockwise
Ecolology
Ecology is the branch of science that examines the relationships organisms have to each other and to their environment.
What two things fuel a storm?
Latent heat, and evaporation of warm waters.
Cyclogenesis applies to mid latitude _______
Mid latitude Cyclones
convergent evolution
Process by which unrelated organisms independently evolve similarities when adapting to similar environments
Biogeography
Study of past and present distribution of organisms
Characteristics of a vapor pressure cell with a small saturated vapor pressure ring
T=40 degrees Fahrenheit Tdew= T air RH=100%
Characteristics of a vapor pressure cell with a medium sized saturated vapor pressure ring
T=60 degrees Fahrenheit Tdew <T air RH<100% RH=50%
Characteristics of a vapor pressure cell with a large sized saturation vapor pressure ring
T=85 degrees Fahrenheit Tdew<< T air RH near 0% RH=20%
what will cause a rising parcel to stop rising, or sink
The air parcel expands as it rises and this expansion, or work, causes the temperature of the air parcel to decrease
relative humidity
The amount of water vapor in the air at any given time is usually less than that required to saturate the air. Expressed as a percentage.
hydrologic cycle
The cycle through which water in the hydrosphere moves; includes such processes as evaporation, precipitation, and surface and groundwater runoff
Which quadrant of a storm has the highest storm surge, wind speed, tornadic activity? And why.
The front right quadrant due to the Coriolis force.
dewpoint temperature
The temperature where water condenses
insect
a class of small arthropod animals that has three separate sections to their bodies: head, thorax, abdomen
ice-albedo feedback
a feedback mechanism that accelerates melting of sea ice and amplify warming
amphibian
cold-blooded vertebrate typically living on land but breeding in water
What are sunspots?
areas of gas on the sun's surface that are cooler than the gases around them
orographic lifting
cloud formation that occurs when warm moist air is forced to rise up the side of a mountain
vapor pressure definition
atmospheric pressure from water vapor
vapor to water
condensation (-)
what are the four lifting mechanisms
convective, orographic, frontal, convergent
four types of clouds in the middle of the sky
cumulonimbus, altocumulus, altostratus, nimbostratus
four types of clouds in the upper most part of the sky
cumulonimbus, cirrocumulus, cirrostratus, cirrus

environment
whats the difference between moist adiabatic lapse rate, dry adiabatic lapse rate, and environmental lapse rate
environmental lapse rate is the rate of decrease in temperature with altitude. moist is saturated, dry is unsaturated
water to vapor
evaporation (+)
water to ice
freezing
frontal lifting
if warm and cool air collide, the warm air will be forced up causing storms
tropical cyclones
intense wind and rain storms that form over oceans in the tropics or EAST PACIFIC
what is different from CO2's current pattern compared to over the past 800 years?
it has been steady all the way up to recent years and has increased greatly
convergence lifting
local low pressures coming together then moving upwards due to the pressure gradient force causing storms
