Final answer:
The ozone layer in the stratosphere protects our planet and its inhabitants from ultraviolet B radiation.
Step-by-step explanation:
The ozone layer in the stratosphere protects our planet and its inhabitants from ultraviolet B radiation. Ultraviolet B (UV-B) radiation is a type of electromagnetic radiation emitted by the Sun, and excessive exposure to UV-B can cause sunburn, skin cancer, and other harmful effects. The ozone layer acts as a shield, absorbing and filtering out most of the UV-B rays, thus protecting life on Earth.
