A farmer has a bucket of fertilizer that will help her plants grow. She followed instructions on the fertilizer bucket, which say to change the phase from a
liquid to a solid before adding it to the plants. What happened to the molecules of
fertilizer when it changed phase?

Explanation:

The molecules of the fertilizer after the phase change are more reactive compared to when in solid phase.

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.
