GOTCHA Flashcards
Natural Resource
Natural resources are resources that are drawn from nature and used with few modifications.
Renewable Resource
A renewable resource is a resource that can be replenished naturally over time.
Nonrenewable Resource
nonrenewable resource refers to a natural substance that is not replenished with the speed at which it is consumed.
Fossil Fuel
a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
Nuclear Fission
a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy.
Nuclear Fusion
Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles.
Hydrogen Fuel Cell Vehicle
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel and an oxidizing agent into electricity through a pair of redox reactions.
Solar Energy
Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy, and solar architecture.
Wind Energy
Wind power or wind energy is mostly the use of wind turbines to generate electricity.
Hydroelectric energy
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower.
Biomass
Biomass is plant-based material used as fuel to produce heat or electricity. Examples are wood and wood residues, energy crops, agricultural residues, and waste from industry, farms and households.
Ethanol
Ethanol is an organic compound. It is a simple alcohol with the chemical formula C₂H₆O. Its formula can be also written as CH₃−CH₂−OH or C₂H₅OH. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like odor and pungent taste.
Geothermal Energy
Geothermal energy is the thermal energy in the Earth’s crust which originates from the formation of the planet and from radioactive decay of materials in currently uncertain but possibly roughly equal proportions.
Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations
Natural Gas
Natural gas is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes.
