Question

Solar energy, which powers most of the physical and biological processes that make up the natural system, comes from which energy process in the sun?

A) Nuclear fusion
B) Solar flares
C) Radioactive decay
D) Photosynthesis

Answer 1

Solar energy comes from the process of nuclear fusion in the Sun, where hydrogen atoms collide to form heavier elements and release energy.

Step-by-step explanation:

The process in the Sun that powers most of the physical and biological processes on Earth through solar energy is nuclear fusion. In the Sun's core, nuclear fusion occurs when hydrogen atoms collide under immense heat and pressure to form heavier elements like helium. This reaction sequence releases vast amounts of energy in the form of light and heat, which we receive as solar energy. Nuclear fusion is the process by which small atomic nuclei, such as hydrogen, combine to form a larger nucleus, releasing energy in the process. This process is what generates the immense heat and light energy that the sun produces.
