3. Why have we not been able to create a fusion reactor on Earth?

Answer :

Answer:

We are not able to create a fusion reactor on Earth because fusion energy production is not based on a chain reaction, as is fission. Plasma must be kept at very high temperatures with the support of external heating systems and confined by an external magnetic field.

Explanation:
Because fusion only occurs at very high temperature (in the centre of a star). That is accomplished in a start because of its great mass creating massive pressure and temperatures. This is extremely hard to recreate on earth.
