Question

Question 1:

Which ones are all renewable resources?

A. coal, biomass, solar

B. hydroelectric, natural gas, solar

C. coal, natural gas, oil

D. hydroelectric, biomass, solar


Question 2:
Massive amounts of destructive energy are released when a nuclear fission bomb explodes. Where does that energy come from?

A. A chain reaction occurs when uranium atoms split, releasing nuclear energy.

B. Molecules break down, releasing chemical energy.

C. Molecules are created, releasing chemical energy.

D. Hydrogen atoms fuse together into helium, releasing nuclear energy.


Question 3:
Where does fission regularly occur and what kind of energy is produced?

A. When wood burns, fission occurs. The energy produced is light and heat.

B. Fission occurs inside the sun. It creates the light and heat that sustain life on Earth.

C. Fission occurs when fossil fuels are burned. The energy can be used to produce electricity.

D. Fission occurs in a nuclear power plant. The energy produced comes in the form of heat.

Question 4:
In a uranium fission reaction, uranium splits into two smaller atoms and energy. Where did the energy come from?

A. Some of uranium's mass is converted into energy, so the smaller atoms have less mass.

B. When the uranium splits, mass and energy are created making the two new atoms.

C. Chemical bonds are broken, and chemical energy is released.

D. The energy had to be the kinetic energy of the atom of uranium before it split.

Question 5:
How does a nuclear power plant produce electricity?

A. Quickly moving neutrons coming out of the reaction create a gas which turns a turbine that produces electricity.

B. Quickly moving neutrons coming out of nuclear reactions are used to turn turbines that produce electricity.

C. Quickly moving neutrons give their kinetic energy to the surrounding water. The water's energy is then used to turn turbines and produce electricity.


D. Quickly moving neutrons coming out of the reaction are slowed down by water. The water heats up and turns into steam. The steam turns the turbine and produces electricity.
