Question 1

Natural Resource

Answer 1

Natural resources are resources that exist without any actions of humankind.

Question 2

renewable

Answer 2

A renewable resource, also known as a flow resource, is a natural resource which will replenish to replace the portion depleted by usage and consumption,

Question 3

Nonrenewable Resource

Answer 3

A non-renewable resource is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. An example is carbon-based fossil fuels.

Question 4

Recycling

Answer 4

Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept.

Question 5

Fossil Fuel

Answer 5

A fossil fuel is a hydrocarbon-containing material formed underground from the remains of dead plants and animals that humans extract and burn to release energy for use.

Question 6

Petroleum

Answer 6

Petroleum, also known as crude oil and oil, is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth’s surface.

Question 7

Natural Gas

Answer 7

Natural gas is a naturally occurring hydrocarbon gas mixture consisting of methane and commonly including varying amounts of other higher alkanes,

Question 8

Coal

Answer 8

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.

Question 9

Acid Precipitation

Answer 9

Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions.

Question 10

Smog

Answer 10

Smog, or smoke fog, is a type of intense air pollution. The word “smog” was coined in the early 20th century, and is a contraction of the words smoke and fog to refer to smoky fog due to its opacity, and odor.

Question 11

Nuclear Energy

Answer 11

Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions.

Question 12

Chemical Energy

Answer 12

Chemical energy is the energy of chemical substances that is released when they undergo a chemical reaction and transform into other substances.

Question 13

Solar Energy

Answer 13

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,

Question 14

Wind Power

Answer 14

Wind power or wind energy is the use of wind turbines to generate electricity. Wind power is a popular, sustainable, renewable energy source that has a much smaller impact on the environment than burning fossil fuels.

Question 15

Hydroelectric Energy

Answer 15

Hydroelectricity, or hydroelectric power, is electricity produced from hydropower. In 2015, hydropower 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.

Question 16

Biomass

Answer 16

Biomass is plant or animal material used as fuel to produce electricity or heat. Examples are wood, energy crops, and waste from forests, yards, or farms.

Question 17

Gasohol

Answer 17

Several common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in internal combustion engines is only possible if the engines are designed or modified for that purpose,

Question 18

Geothermal Energy

Answer 18

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.
