People use land resources to help them meet their needs. Coal is a fossil fuel that people mine from the land. They burn coal to make electricity. Which type of resource is coal?

• A green living resource

• A green energy resource

• A renewable energy resource

• A nonrenewable energy resource

Students classify resources as renewable and nonrenewable. They create a table to organize their data. Which resource below best completes the table?

• Air

• Wind

• Oil

• Soil

Scientist are looking for ways to produce energy from natural materials, such as plants, without depleting limited natural resources. Plants are considered a good alternative because they are_________

• nonrenewable

• reusable

• renewable

• none of these

One disadvantage of using renewable resources is______

• They can be replenished in a short period of time

• Using them decreases the supply

• They reduce the demand of fossil fuels

• They have a positive impact on our environment

Many of our daily routines rely on the use of nonrenewable resources. Because there is only a limited supply available, conserving these resources is very important. What is another important reason to conserve these limited supplies?

• To learn how to function when the supplies run out.

• To create more nonrenewable resources.

• To harm the environment and cause drastic changes.

• To increase the cost of resources.

Which item in the picture is an example of a nonrenewable resource?

• Animal

• Cactus

• Wind

• Oil

Which best explains why air is classified as a renewable resource?

• It is recycled in the water cycle.

• It is formed over time by heat and pressure.

• It is recycled in one of Earth's natural cycles.

Match the following

• Wind Turbines

• Energy sources that are created by the burning of ancient buried organic matter and extracted as coal, petroleum, and natural gas

• Fossil Fuels

• The energy harnessed from the movement of water, usually in the form of flowing or falling water

• Solar Power

• The conversion of radiant (light) energy into electric energy.

• Hydroelectric Power

• The unequal heating of air masses causes movement of air which spins turbines (kinetic energy) to create electric energy.
