Definitions:

Ozone Molecules

A molecule made up of three oxygen atoms, playing a crucial role in absorbing the sun's ultraviolet radiation in the stratosphere, thus protecting life on Earth.

Stratosphere

The layer of the atmosphere between the troposphere and the mesosphere. It contains a thin ozone layer that protects life by filtering out much of the sun’s ultraviolet radiation.

UV Radiation

Ultraviolet radiation, a type of energy emitted by the sun and artificial sources, which is invisible to the human eye and can cause skin damage.

Extinct Species

Species that no longer exist; having no living members.
