Question 3

Nonrenewable Resource

Answer 3

a resource that forms at a rate that is much slower than the rate it is consumed

Question 4

Recycling

Answer 4

the process of recovering valuable or useful materials from waste or scrap: the process in reusing the same items

Question 5

Fossil Fuel

Answer 5

a nonrenewable energy resource formed from the remains of organisms that lived long ago, oil, coal, and natural gas

Question 6

Petroleum

Answer 6

a liquid mixture of complex hydrocarbon compounds, used widely as a fuel source

Question 7

Natural Gas

Answer 7

liquid mixture of gaseous hydrocarbons located under the surface of earth, often near petroleum deposits, used as fuel

Question 8

Coal

Answer 8

is a flammable black hard rock used as a solid fossil fuel. It is mainly made up of 65-95% carbon and also contains hydrogen, sulphur, oxygen and nitrogen. It is a sedimentary rock formed from peat, by the pressure of rocks laid down later on top.

Question 9

Acid Precipitation

Answer 9

Any form of precipitation, including rain, snow, hail, fog, or dew, that is high in acid pollutants, especially sulfuric and nitric acid. Acid precipitation has a pH of less than 5.6 (the normal acidity of unpolluted atmospheric water) and is often less than pH 5.0. Also called acid rain.

Question 10

Smog

Answer 10

fog or haze combined with smoke and other atmospheric pollutants.

Question 11

Nuclear Energy

Answer 11

is the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant. The term includes nuclear fission, nuclear decay and nuclear fusion

Question 12

Chemical Energy

Answer 12

Chemical energy, Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic.

Question 13

Solar Energy

Answer 13

Image result for Solar 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, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.

Question 14

Wind Power

Answer 14

is the use of air flow through wind turbines to mechanically power generators for electric power. Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little land

Question 15

Hydroelectric Energy

Answer 15

Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydropower. The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir.

Question 16

Biomass

Answer 16

is fuel that is developed from organic materials, a renewable and sustainable source of energy used to create electricity or other forms of power.

Question 17

Gashol

Answer 17

a mixture of gasoline and ethyl alcohol used as fuel in internal combustion engines.

Question 18

Geothermal Energy

Answer 18

s the heat from the Earth. It’s clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth’s surface, and down even deeper to the extremely high temperatures of molten rock called magma.
