PLEASE ANSWER:Once started, why can nuclear fission continue to occur on its own? The thermal energy released can cause the products to join.

The neutron formed by the reaction can cause more nuclei to combine.

The thermal energy released can cause the products to split.

A neutron begins the reaction, and more neutrons are formed in it.
