PLEASE HELP ME !! Observe the details of these three images. What inferences can you
make about the changes in the logs? The law of conservation of mass applies to ALL physical and
chemical changes. How are these three images different? What happens to the matter stored within
the logs as the fire burns?

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.
