Verified step by step guidance

Understand that the sun emits various types of radiation, including ultraviolet (UV) radiation, which can interact with living tissues.

Recognize that ionization is a process where an atom or molecule gains or loses electrons, resulting in the formation of ions.

Identify that UV radiation has enough energy to cause ionization in biological molecules, leading to the formation of free radicals and other reactive species.

Acknowledge that these reactive species can damage cellular components such as DNA, proteins, and lipids, leading to harmful effects on living tissues.

Conclude that ionization is the process responsible for the damaging effects of the sun's radiation on living tissues, as it initiates chemical reactions that can harm biological systems.
