Hydrogen bombs and stars both produce energy with nuclear

Answer;

- Nuclear fusion

Explanation;

-Hydrogen bombs and stars both produce energy with the nuclear fusion. On other side, the Sun and other stars make heat and light by nuclear reactions.

-The first stage of a hydrogen bomb involves a fission explosion which in turn leads to a nuclear fusion. The extreme heat and pressure from the initial atomic blast force together deuterium and tritium (two light gases made of hydrogen). When they are forced together, some of the hydrogen atoms fuse to one another, creating helium.

-This process of fusion releases even more energy per unit of mass than fission does, and the energy released from the fusion reaction also feeds back into the fission reaction, increasing its output.

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

the answer is to check all of them! they all apply well at least i think so!
