Paragraph: (Science-textbook/science-g4-41.txt)
Sent 1: The center of an atom is held together by powerful forces.
Sent 2: This gives them a huge amount of stored energy.
Sent 3: This type of energy is called nuclear energy.
Sent 4: This energy can be released and used to do work.
Sent 5: This happens in nuclear power plants where they split apart the nucleus of an atom.
Sent 6: This splitting apart is called nuclear fission.
Sent 7: Another type of nuclear energy happens in the Sun.
Sent 8: Here the atoms nuclei are not split apart.
Sent 9: Instead, the nuclei of the atoms are fused, or joined together.
Sent 10: This process is called nuclear fusion.
Sent 11: Some of the suns energy travels to Earth.
Sent 12: This energy from nuclear fusion warms the planet and provides the energy for photosynthesis.

Question: Nuclear fusion happens inside what space body? (false/0)

Question: What type of stored energy do atoms have? (false/1)

Question: Some of the suns energy travels to earth, what is the energy used for on earth? (true/2)

Question: What are the 2 processes called to form nuclear energy? (true/3)

Question: What type of nuclear energy process occurs in the sun? (true/4)

Question: What are the two nuclear processes called? (true/5)

Question: What is the process called when the nuclei of the atoms are fused, or joined together. (true/6)

Question: What is the process to produce nuclear energy in nuclear powerplants called? (true/7)

Question: How do nuclear fission and nuclear fusion differ? (true/8)

Question: What happens to atoms during nuclear fusion? (false/9)

Question: What is the stored energy at the center of the atom called? (true/10)

Question: What happens to the energy of an atom if the nucleus is split apart? (false/11)

"It's released."
The energy converts
Becomes kinetic energy
The atoms fuse back together
Causes photosynthesis
In a process called nuclear fission
This energy can be released and used to do work
In a process called rebound fusion
The energy is released

Question: What can be done with the stored energy that holds the center of atoms together? (false/12)

Question: Some of the Sun's energy travels to Earth and becomes energy for what process? (true/13)

Question: Do the atoms nuclei in the Sun split apart? (true/14)
