This is the process of studying a forest to determine whether or not it is ready for harvesting by measuring the diameter, height, and type of trees.
What is timber cruising?
300
This genetic material resource can be harvested while it is ripe and used as food, or can be harvested later when the moisture content is reduced and is used for ethanol production.
What is corn?

This is an easy way to remember the intake, compression, combustion, and exhaust stages in a turbine engine.
What is "suck-squeeze-bang-blow?"
400
In this form of logging, all trees, regardless of species or size, are removed from a plot of land. When replanting, the number of tree species can be controlled.
What is clear-cutting?

A mineral that has a metal chemically combined with other elements, it can be processed to separate the metal.
What is an ore?
400
Composed of light hydrocarbons, this is a combustible gas occurring in porous rock.
What is natural gas?
400
In this method, mined coal is combined with steam and oxygen and becomes a mixture of carbon monoxide, hydrogen, and methane to be used in place of natural gas.
What is gasification?
500
This process, which is actually "farming in the water," includes fish farming, shrimp farming, oyster farming, algaculture (such as seaweed farming), and the cultivation of ornamental fish.
What is aquaculture?
500
This oily, flammable mixture of hydrocarbons is widely used in producing plastic resins such as polypropylene and polyethylene.
What is petroleum?
500
While minerals are chemical compounds, these natural resources are different because they are chemical mixtures.
What are fossil fuels?
500
Abbreviated CNG, this form of hydrocarbon fuel is compressed and used as a fuel for some automobiles and vehicles.
What is compressed natural gas?
500
This requires a vertical shaft to reach the coal deposit, where workers then dig horizontal shafts to remove the coal.
