What are a few effects power plants have on the environment?

Harmful chemicals and ash is released.

Rain becomes acid.

Pollutes air and water.

The damage to our planet is done, there is nothing we can do to help. 

What is false?  We have lots to do!

200

Buildings, power tools, cars and electronic devices all have this in common.

They all use energy

200

Three examples of fossil fuels

Coal, petroleum and natural gas.

200

The energy of moving water

Hydropower

There are two ways to extract fossil fuels.  What are the two ways and how do they effect the environment?

Mining and drilling. They change up the land and harm the environment with all the construction and digging.


200

Fossil fuels combine with oxygen to produce heat and light.

Combustion?

300

My purpose in a power plant is to allow excess heat to escape.

What is a cooling tower?

300

Define fossil fuels.

Materials that formed as ancient plants and animals decayed underground.

300

How is the sun connected to wind energy?

The sun heats up the earth which makes air move around.

300

What does a scrubber do?

A scrubber is a machine that allows gases from a power plant to pass through in order to reduce the amount of pollutants that get into the air.

300

What unstable element is used for nuclear energy? How is energy released from it?

Uranium. The atoms are split to create heat.

400

Why might a solar car have difficulty traveling at night? 

There is no sun to give solar energy.

400

What is the difference between the formation of coal and petroleum?

Coal uses dead plants that turn into peat. Petroleum uses plants and animals.

400

Explain geothermal energy.

Geothermal energy is heat energy obtained from beneath the Earth's surface.

400

List 5 harmful outcomes caused by human uses of energy.

Answers vary

400

What are greenhouse gases?

A pollutant that heats up the earth.

500

What is the function of a generator in a power plant?

It changes the energy of motion into electrical energy.

500

Why do people rely so heavily on fossil fuels if they are nonrenewable?

They are inexpensive and readily available.

500

What is biomass? What is it made of?

Biomass is made from plant materials such as wood and nut shells.

500

What are two ways oil can become harmful?

Pipes can leak and spread oil everywhere. Ships transporting can collide and pollute water with oil.

500

Where is chemical energy stored?

batteries
