Without the sun, life on earth would not exist. There would be no warmth, no plants, no animals, no night and day. To power itself, the sun is constantly generating a nuclear reaction in its core, in which hydrogen nuclei are combined to form helium. This process is known as fusion, and __________ a massive amount of energy.

Respuesta :

this process is known as fusion and radiance

Answer:

Releases

Explanation:

Nuclear fusion is a process where nuclei of lighter elements are fused together to make a heavier element. In this process a huge amount of energy, nuclear energy, is released. The Sun also gets it energy from the same process. In its core, where temperature is around 15 million kelvin, hydrogen nuclei fuse together to make helium.

This process is proposed to be used to generate power on Earth as well. But till now no efficient system has been developed. As fusion can only start under certain condition. Inside the core such conditions occur naturally.
