Explanation:

"Gravitational force" is a kind of force that  will attract any object with a mass. It is a  "natural phenomenon" where all the things, including in planets in-universe, of mass or energy, are brought towards each other.

petroleum? coal maybe?

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
