100
When a fuel source is used to generate both electricity and useful heat.
What is cogeneration.
100
The normal temperature gradient in the atmosphere is altered as the air temperature at the Earth's surface is cooler than the air at higher altitudes.
What is a thermal inversion.
100
The second leading cause of lung cancer in America.
Exposure to radon gas, which can lead to radon-induced lung cancer.
100
The measure of the area of land and water an individual population, or activity, requires to produce all the resources it consumes and to process the waste it generates and its measurement in units.
What is the Ecological Footprint and hectares (ha).
100
The tendency of a shared limited resource to become depleted if it is not regulated in some way.
What is Tragedy of the Commons.
200
In our electricity audit, we found the total consumption of electricity from 2022-2023 to be 2,945,742 kWh and estimated that approximately 26% of that electricity was required to power the school's lighting. Approximately how many kWh were consumed for lighting at THS from 2022-2023?
2,945,742 kwh x 0.26 = 76,589.24 kwh
200
Normal temperature gradient above the Earth's surface.
What is:
--> warm above Earth's surface (troposphere)
--> cooler as you reach the mountain top (troposphere)
--> warmer due to layer absorbing UV rays like a pool surface (stratosphere)
--> low density and low absorption of UV rays (mesosphere) = coldest place on Earth at -150o F
--> high absorption of highly energetic solar radiation (thermosphere) = hottest place on Earth at 3100o F
200
This diagnosis / condition is most affected by particulate matter in the atmosphere.
What is Asthma.
200
Being able to use a resource or engage in an activity now without jeopardizing the ability of future generations to engage in similar activities later.
What is Sustainability.
300
a) Name 3 types of surface mining. Which is most damaging the local ecosystems?
b) The unfortunate eventual outcome/consequence of surface mining?
a) What is:
1. open pit mining
2. strip mining
3. Mountaintop removal mining
*Requires heavy equipment to move removed overburden down hill and is the most damaging to landscape and habitats, especially nearby streams.
b) What is increasingly scarce ore reserves requiring mining move deeper underground (subsurface mining), which is more dangerous & expensive.
300
Air density is proportional to concentration and inversely proportional to movement of particles and air temperature. Thus, cold air is less dense with higher concentration and less movement of particles. Therefore cold air will have more or less air pollutants?
What is more air pollutants due to lack of movement and buoyant forces leading to a concentration of particles.
300
This is how photochemical smog is formed.
Nitrogen oxides (NOx) and volatile organic hydrocarbons (VOCs) react with heat and sunlight to produce a variety of pollutants.
300
The largest quantity of a renewable resource that can be harvested indefinitely.
What is Maximum Sustainable Yield (MSY).
400
1) Soil, vegetation, & rocks that are removed to get to valuable minerals (ore) deposit below (during surface mining).
2) Leftover waste material separated from the valuable metal or mineral within ore (often stored in ponds at the mining site).
1) What is overburden.
2) What is tailings and slag.
400
Forms when NO2 is broken by sunlight (brightest in early afternoon) and free O binds to O2.
What is tropospheric ozone, which causes respiratory irritation and is not protective like stratospheric ozone (O3).
400
Maximum Sustainable Yield (MSY) with the fastest growth/harvest is often reached when the population size is at this point.
What is about one-half the carrying capacity.
500
The use of energy resources is not evenly distributed between developed and developing countries. This is the cheapest and most available energy resource in less developed countries.
What is biomass (wood, peat, dung, other organic waste).
500
Methods to reduce air pollution from coal-burning power plants.
What are scrubbers and electrostatic precipitators (filtration devices that remove particulate matter (PM2.5) from gas being released from coal-fired power plants).
500
Maximum Sustainable Yield applies to reproducing these biological populations. Name 3.
What is:
-fish
-timber
-agricultural products
-gathered plants
-hunted animals
*Point deducted for referring to non-renewable and/or mineral resources
