why is a nuclear fusion rare?

Sagot :

Answer:

because it requires very rare conditions (extreme heat and lots of energy)

Explanation:

Temperatures of approximately 150,000,000 °C (around the temp. of the sun) are required for fusion to occur on Earth therefore it is very difficult to achieve. It mostly happens in stars.
