Renewable and Nonrenewable Resources Review

Front

What are fossil fuels?

Back

Fossil fuels are natural resources formed from the remains of ancient plants and animals, which have been buried and subjected to heat and pressure over millions of years. Examples include coal, oil, and natural gas.

Front

Why are fossil fuels considered non-renewable resources?

Back

Fossil fuels are considered non-renewable because they take hundreds of millions of years to form, and once depleted, they cannot be replaced within a human timescale.

Front

What is wind energy?

Back

Wind energy is the energy obtained from the wind using wind turbines to convert kinetic energy from wind into mechanical power or electricity.

Front

What do you see at a wind farm?

Back

At a wind farm, you would see several dozen wind turbines that harness wind energy to generate electricity.

Front

What is a drawback of wind energy?

Back

A drawback of wind energy is that there aren't enough suitable sites in the U.S. to build wind farms, which can limit its expansion.

Front

True or False: Flowing water is an example of biomass.

Back

False. Flowing water is not biomass; biomass refers to organic materials, such as plants and animal waste, that can be used as fuel.

Front

What is biomass?

Back

Biomass is organic material that comes from plants and animals. It can be used as a renewable energy source when burned or converted into biofuels.

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting an atom's nucleus apart, releasing a large amount of energy, which can be harnessed for electricity.

Front

What are renewable resources?

Back

Renewable resources are natural resources that can be replenished naturally over time, such as solar energy, wind energy, and hydropower.

Front

What are non-renewable resources?

Back

Non-renewable resources are natural resources that cannot be replenished within a human timescale, such as fossil fuels and nuclear fuels.
