Natural Resources Quiz

What are two things that limit the amount of natural resources available?

1. How long it takes for the Earth to replace 2. How much humans use

Nonrenewable resources

A natural resource that is not replaced in a useful time frame (more than a lifetime)

Combustion

A process of burning fuel that results in fire/thermal energy

Fuel

A substance that provides energy as the result of a chemical change

Renewable resources

Any natural resource that can replenish itself in a relatively short period of time, usually no longer than the length of a human life.

A diamond is created from which element?

Carbon

Active Solar System

Converts light from the sun into thermal energy

Geothermal Energy

Energy from steam or hot water produced from hot or molten underground rocks.

Hydroelectric power

Power generated from moving water.

Advantages of solar power

Solar power won't run out for billions of years and it does not cause pollution.

Examples of renewable resources

Trees, air, water

Solar cells might power items like...

calculators, lights, telephones

Coal forms from

decaying plants that are covered in the Earth. Heat and pressure, over millions of years, turn those remains into coal.

biomass energy

energy produced by burning organic matter, such as wood, food scraps, and alcohol

Hydrocarbons are

energy-rich chemical compounds that make fuel.

Fossil fuels are

formed over millions of years because extreme heat and pressure were applied to the remains of plants and animals trapped between rock layers in the Earth-Coal, Oil, and Natural Gas

Oil forms

from the remains of small animals, algea, and protists.

Natural Gas forms

from the same organisms as oil (remains of small animals, algea, and protists), but it is less dense so it rises above an oil deposit.

The most widely used renewable source of energy is ____________________.

hydroelectric energy

examples of nonrenewable resources

minerals and fossil fuels like coal, oil, natural gas

The fossil fuel that produces the least amount of air pollution is ____________________.

natural gas

Wind energy is actually an indirect form of __________________ energy.

solar

Energy conservation

the practice of finding ways to use less energy or to use energy more efficiently

Fossil Fuels are energy rich because

they contain hydrocarbons

Extract

to remove or take out
