natural resources Flashcards
materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain.
Natural Resource
A renewable resource is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale.
Renewable Resource
A non-renewable resource is a resource of economic value that cannot be readily replaced by natural means at a quick enough pace to keep up with consumption. An example is carbon-based fossil fuel. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas
Nonrenewable Resource
the action or process of converting waste into reusable material.
Recycling
a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
Fossil Fuel
a liquid mixture of hydrocarbons that is present in certain rock strata and can be extracted and refined to produce fuels including gasoline, kerosene, and diesel oil; oil.
Petroleum
flammable gas, consisting largely of methane and other hydrocarbons, occurring naturally underground (often in association with petroleum) and used as fuel.
Natural Gas
a combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel.
Coal
Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions. It can have harmful effects on plants, aquatic animals and infrastructure.
Acid Precipitation
fog or haze combined with smoke and other atmospheric pollutants.
Smog
the energy released during nuclear fission or fusion, especially when used to generate electricity.
Nuclear Energy
Chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances. Examples include batteries, food, gasoline, and etc.
Chemical Energy
Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photostatic, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.
Solar Energy
Wind power or wind energy is the use of wind to provide the mechanical power through wind turbines to turn electric generators and traditionally to do other work, like milling or pumping
Wind Power
Hydroelectricity is electricity produced from hydro power. In 2015, hydro power generated 16.6% of the world’s total electricity and 70% of all renewable electricity, and was expected to increase by about 3.1% each year for the next 25 years
Hydroelectric Energy
Biomass is plant or animal material used for energy production, or in various industrial processes as raw material for a range of products. It can be purposely grown energy crops, wood or forest residues, waste from food crops, horticulture, food processing, animal farming, or human waste from sewage plants
Biomass
a mixture of gasoline and ethyl alcohol used as fuel in internal combustion engines.
Gasohol
Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth’s crust originates from the original formation of the planet and from radioactive decay of materials.
