1. Nuclear fission-the nucleus of a
radioactive atom splits apart into smaller
nuclei, releasing energy.
(Draw the picture)
- Fission happens on Earth in naturally
radioactive elements found within the
earth’s crust and in nuclear reactors.
- Control rods keep the reaction under
control.
- Produces radioactive waste.

2. Nuclear fusion is the process by which
smaller nuclei join together to form a
heavier nucleus.
(Draw the picture)
• Fusion is accompanied by the release of
energy:
- this energy is in the form of light,
heat and radiation.
- fusion occurs in the core of stars and
is why stars shine and give off heat.
Fusion needs extremely high heat
energy to occur(>15,000,000°C) and
high pressure.
Review
Nuclear fission:
A large nucleus splits into several
small nuclei when impacted by a
neutron, and energy is released in
this process
Nuclear fusion:
Several small nuclei fuse
together and release
energy.
