The process of breaking up molecules into their component parts is:

The correct answer is ionization.

Ionization refers to the procedure by which a molecule or an atom attains a negative or positive charge by losing or gaining electrons to produce ions, usually in combination with other chemical modifications.

Ionization can result due to the loss of an electron after collisions with other atoms, subatomic particles, molecules, and ions, or through the association with electromagnetic radiation.

Explanation:

at summer season the snow will melt and will produce water and using generators we can produce electric energy.

and in spring and winter can produce electric energy also using the wind
