EVSC 3300 - EXAM ONE LATEST EXAM WITH ACTUAL
QUESTIONS AND CORRECT VERIFIED ANSWERS|ALREADY
GRADED A+|


what causes weather? - <<ANSWER>>-the effect of the Sun on
the Earth
--differences in density and pressure as a result of differences in
temperature

climate - <<ANSWER>>-of a region, is the condition of the
atmosphere over many years
--the average of weather
-described by long-term averages of atmospheric conditions such
as precipitation

climatology - <<ANSWER>>study of climate
-climatologists and climate scientists also study changes of
climate in the past and for the future

meteorology - <<ANSWER>>study of:
-weather variables -- temperature, humidity, pressure, wind speed
and direction, cloud cover, precipitation
-the processes that cause weather
-the interaction of the atmosphere with the Earth's surface and
ocean

natural disasters - <<ANSWER>>hurricanes, tornados, floods,
blizzards/snow/ice

what is the atmosphere? - <<ANSWER>>-a fluid

,-a thin layer surrounding the Earth
-mainly a mixture of invisible gas with some solid and liquid
particles that stays in place on account of the force of gravity
-Earth's diameter = ~8000 miles
-atmosphere = ~100 miles

atmospheric composition - <<ANSWER>>-permanent and
variable gases
aerosols

permanent atmospheric gases - <<ANSWER>>-nitrogen: 78.08%
-oxygen: 20.95%
-argon: .93%
-neon: .0018%
-helium: .0005%
-hydrogen: .00006%
-xenon: .000009%

variable atmospheric gases - <<ANSWER>>-water vapor: 0-4%
by volume
-CO2: 410ppm (.041% by volume)
-CH4: 1.8ppm (.00018% by volume)
-N2O nitrous oxide: .3ppm (.00003%)
-ozone: .04ppm (.000004% by volume)
-particles (dust, soot, etc.): .01-.15ppm (.000001% by volume)
-chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs):
.0001ppm (.00000001% by volume)

evolution of the Earth's atmosphere - <<ANSWER>>-4.5 billion
years ago: hydrogen and helium
-volcanic eruptions --> water vapor, carbon dioxide, nitrogen
-Earth's cooling --> clouds --> surface water
-carbon dioxide dissolved and accumulated in oceans
-bacteria in water (first) and vegetation (later) produce oxygen
(photosynthesis)

,-nitrogen is chemically stable and accumulated in the atmosphere

-variable gases are vital to meteorology and climatology
--to understand atmospheric concentrations of trace gases, their
sources and sinks need to be investigated




composition of atmosphere near Earth's surface -
<<ANSWER>>Nitrogen, Oxygen, Argon, Neon, Helium,
Hydrogen, Xenon, etc.

weather - <<ANSWER>>-the condition of the atmosphere at a
particular location and moment
-these atmospheric conditions include, among others,
temperature, humidity, pressure, wind speed and direction, cloud
cover, and precipitation


Oxygen (20.95%) - <<ANSWER>>SOURCES:
-photosynthesis
-ocean phytoplankton
SINKS:
-decay of organic matter
-oxidation
-combustion
-respiration

Nitrogen (78.08%) - <<ANSWER>>SOURCES ("denitrification"):
-decaying plant and animal matter
SINKS ("nitrogen fixation"):
-soil bacteria
-lightning -- hot enough to break N2 and form nitrous oxides
(NOx)

, Water Vapor (0-4%) - <<ANSWER>>-greenhouse gas (something
that reabsorbs IR radiation from Earth's surface)
SOURCES:
-evaporation (liquid to water)
-sublimation (ice to vapor)
-transpiration
SINKS:
-condensation (vapor to liquid)
-deposition (vapor to ice)
-precipitation

Water cycle:
-sublimation, deposition, melting/evaporation

Carbon Dioxide - <<ANSWER>>greenhouse gas
SOURCES:
-biomass decay
-respiration
-combustion
-deforestation
-volcanic eruptions
SINKS:
-photosynthesis
-ocean phytoplankton
-dissolved directly into ocean surface

Atmospheric CO2 concentration chart:
--KEELING CURVE

Average Mauna Loa CO2:
-Dec. 2023: 421.86ppm
-Dec. 2022: 418.99ppm

Methane (1.9ppm) - <<ANSWER>>greenhouse gas
