Ecology Final Exam

Organisms require constant inputs of energy

All environmental problems are related to production and use of __________.

Florida is among the worst states n terms of energy use/overuse

Define air pollution

Air Pollution Forms: [blank_start]aerosols[blank_end]: solid particles carried in air [blank_start]gasses[blank_end]: 90% of air pollution Types: Primary: [blank_start]exert effect in original form[blank_end] ([blank_start]SO2[blank_end]) Secondary: [blank_start]form in atmosphere from other precursors[blank_end] ([blank_start]O3[blank_end]) Factors: [blank_start]residence[blank_end] time weather/topography

All pollutants are inherently harmful and devastate the global climate

A measure of particulate matter (PM) measures the ______ of particles in the air.

How is ozone formed?

[blank_start]Gasses[blank_end] have a greater residence time than [blank_start]aerosols[blank_end], and [blank_start]secondary aerosols[blank_end] have a greater residence time than [blank_start]primary aerosols[blank_end].

Place the atmospheric zones in order with the outermost layer on top and the innermost layer (closest to the earth) on the bottom. [blank_start]Thermosphere[blank_end] [blank_start]Mesosphere[blank_end] [blank_start]Stratosphere[blank_end] [blank_start]Troposphere[blank_end]

The inversion layer is when [blank_start]cool[blank_end] air falls under [blank_start]warm[blank_end] air in a valley or depression and causes a foggy layer.

Pollutants: source, effects SO2: [blank_start]coal-fired power plants[blank_end], [blank_start]kills plants/can get in skin[blank_end] NOx: [blank_start]high-E combustion[blank_end], [blank_start]forms ozone in air[blank_end] CO2: [blank_start]fossil fuel combustion[blank_end], [blank_start]global warning[blank_end] toxic metals (Hg): [blank_start]coal burning[blank_end], [blank_start]cytotoxin & bioaccumulation[blank_end]

Why is burning coal so detrimental to the environment?

Acid deposition is the most indirect form of pollution

Check the effects of acid deposition

___________ occurs when solar radiation breaks the intramolecular bond in O2 to form 2O. Then one of the solitary O atoms bonds with another O2 molecule to form ozone.

___________ occurs when solar radiation breaks the intramolecular bonds in O3 to form O2 and O. Then one of the solitary O atoms bonds with another O3 molecule to form 2O2.

Which of the following is the catalyst for ozone destruction?

The term "greenhouse effect" was coined by

How are global climate changes most felt by the world?

Ultravioloet light is [blank_start]high[blank_end] energy and [blank_start]short[blank_end] wavelength while infared light is [blank_start]low[blank_end] energy and [blank_start]long[blank_end] wavelength.

The greenhouse effect describes a phenomenon where increasing output of certain gasses is causing the atmosphere to become a more effective "blanket," trapping more heat in it

Check the greenhouse gasses

Which two of the greenhouse gasses are the largest issue right now?

Carbon dioxide levels undergo seasonal fluctuation. CO2 goes [blank_start]up[blank_end] in the winter due to [blank_start]respiration release[blank_end], and [blank_start]down[blank_end] in the summer due do [blank_start]photosynthesis absorption[blank_end].

High CO2 and CH4 concentrations correspond to cool interglacial periods

A __________ station is used to determine the climate history from before recorded history by coring into glaciers and examining the layers of ice.

The Clean Air Act of 1970 delt with the issue of "acid rain" and targeted __________ emissions

Hydrogen ion wet deposition was mainly concentrated in the ________ region of the united states

Check all that apply to the Montreal Protocol of 1987 targeted chlorofluorocarbons. Check all that apply to chlorofluorocarbons.

Algal blooms are a major concern mostly because of the release of __________ in the water.

Check all that applies to coral bleaching.
