Answer 5

Potential

Question 6

Give 2 examples of renewable energy sources

Answer 6

Wind Hydropower Solar Geothermal

Question 7

What are fossil fuels

Answer 7

Plant and animal remains from millions of years ago that turned into fuels from intense heat and pressure

Question 8

What is a photovoltaic?

Answer 8

A device that changes sunlight directly into electricity

Question 9

If nuclear power plants are so highly efficient, why don’t we use them more often?

Answer 9

Even though they produce very little waste, the waste they do produce is extremely dangerous. The waste product must be stored very carefully and lasts for hundreds of years.

Question 10

Where does geothermal energy come from?

Answer 10

Molten rock (magma) from deep inside earth’s core

Question 12

What are 3 cons to using wind energy?

Answer 12

It can affect bird and bat population. It takes a lot of space. It produces a great amount of noise

Question 13

Answer 13

False. Nuclear power is nonrenewable.

Question 14

What are two things that affect on object’s kinetic energy.

Answer 14

Its mass and velocity. If either of these increases, the kinetic energy increases also

Question 15

What is the job of the transformer?

Answer 15

Besides helping save earth from deceptacons…joking.

transformers take the electricity from the generator and amplify it–make it into a higher voltage.

Question 16

Burning Wood uses this type of energy.

Answer 16

Biomass

Question 17

There is enough solar energy that hits the earth everyday to power the earth for more than a year. Why don’t we use it more often?

Answer 17

1) It’s very expensive
2) We can’t control sunlight. There are days it doesn’t shine and to store it takes huge storage devices.
3) Solar panels (photovoltaics) must be very large to generate great amounts of energy.
