The process of splitting an atom into two lighter atoms is called
a. nuclear disintegration.
b. nuclear separation.
c. nuclear fission.
d. nuclear fusion.

Answer is: C. nuclear fission.

Nuclear fission is a nuclear reaction or a radioactive decay where nucleus of atom split into smaller ligher nuclei.

Nuclear fission is exothermic reaction which release large amounts of energy (electromagnetic radiation or as kinetic energy, which heat reactors where fission reaction take place).

The process of splitting of an atom into two lighter atoms is called is called nuclear fission.

Explanation:

There are two types of nuclear decay reactions:

Hence, the process of splitting of an atom into two lighter atoms is called is called nuclear fission.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
