Question

what might happen if the ozone layer did not block the suns ultraviolet rays?
a humans would be able to see in the ultraviolet range of the em spectrum
b devices that use electromagnetic radiation would no longer work
c the surface of the earth would be much hotter
d rates of skin cancer would skyrocket

Explanation:

The ozone layer protects Earth by absorbing most of the sun's harmful ultraviolet (UV) radiation. Exposure to high - levels of UV radiation is a major risk factor for skin cancer. Humans cannot see UV light regardless of the ozone layer status. Devices using electromagnetic radiation are not affected by ozone layer presence or absence in a direct way. The greenhouse effect and other factors mainly determine Earth's temperature, not the ozone layer's role in UV - blocking.

Answer:

D. Rates of skin cancer would skyrocket
