6.4 Renewable and Nonrenewable Resources

Front

What is a renewable resource?

Back

A renewable resource is a natural resource that can be replenished or regenerated over time, such as solar energy, wind energy, and hydropower.

Front

What is a nonrenewable resource?

Back

A nonrenewable resource is a natural resource that cannot be replenished in a short period of time, such as fossil fuels (coal, oil, natural gas) and nuclear energy.

Front

What is geothermal energy?

Back

Geothermal energy is heat energy that comes from the Earth's interior, which can be used for heating and electricity generation.

Front

What is solar energy?

Back

Solar energy is the energy obtained from the sun's rays, which can be converted into electricity or heat.

Front

What is hydropower?

Back

Hydropower is energy derived from the movement of water, typically used to generate electricity.

Front

What is wind energy?

Back

Wind energy is the energy generated from the movement of air, which can be harnessed using wind turbines to produce electricity.

Front

What is the main source of energy for most natural resources?

Back

The main source of energy for most natural resources is the sun.

Front

What is the energy transformation in a coal-fired energy plant?

Back

The energy transformation in a coal-fired energy plant is chemical energy (from coal) to mechanical energy (from steam) to electrical energy.

Front

What is the role of the sun in renewable energy?

Back

The sun provides energy that can be harnessed through solar panels, which convert sunlight into electricity.

Front

What is the difference between renewable and nonrenewable resources?

Back

Renewable resources can be replenished naturally over time, while nonrenewable resources are finite and cannot be replaced once used.
