Natural Resources

Question 1

Natural Resource

Answer 1

materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain.

Question 2

Renewable Resource

Answer 2

a resource which can be used repeatedly and replaced naturally. Examples include oxygen, fresh water, solar energy, timber, and biomass. Renewable resources may include goods or commodities such as wood, paper and leather.

Question 3

Nonrenewable Resource

Answer 3

are those found inside the earth, and they took millions of years to form. These include the fossil fuels, oil, natural gas, and coal and nuclear energy. Today, close to 84% of the total amount of energy used globally comes from fossil fuels

Question 4

Recycling

Answer 4

convert (waste) into reusable material.

Question 5

Fossil Fuel

Answer 5

is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth’s crust over hundreds of millions of years.

Question 6

Petrolium

Answer 6

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.

Question 7

Natural Gas

Answer 7

is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.

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

is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.

Question 10

Smog

Answer 10

fog or haze combined with smoke and other atmospheric pollutants.

Question 11

Nuclear Energy

Answer 11

Nuclear power plants split uranium atoms inside a reactor in a process called fission. At a nuclear energy facility, the heat from fission is used to produce steam, which spins a turbine to generate electricity.

Question 12

Chemical Energy

Answer 12

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

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

wind energy or wind power describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power.

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

the total mass of organisms in a given area or volume.

Question 17

Gasohol

Answer 17

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

Question 18

Geothermal energy

Answer 18

Geothermal energy is 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.
