Great amounts of energy are released

in the core of a star as lighter elements
combine and form heavier elements
during the process of
(1) compaction
(2) condensation
(3) radioactive decay
(4) nuclear fusion

Answer 1

Great amounts of energy are released in the core of a star as lighter elements combine and form heavier elements during the process of nuclear fusion.

Step-by-step explanation:

• Nuclear fusion is the defined as the fusion or combination of many lighter elements to form heavier element.

• Example: Two hydrogen nuclei combine or fuse to form a helium. The greatest amount of energy in star is its hydrogen which gets exhausted consequently resulting in burning of helium and forming heavier elements.
