What is the ozone Layer?
Lower layer of the stratosphere that contains a high concentration of ozone.
In the lower layers of the stratosphere the amount of ozone in the air goes from less than 1 ppm to around 10 ppm. The cause of this is UV light from the sun striking regular oxygen molecules and causing them to split into 2 oxygen atoms. Each of these atoms attaches to a regular oxygen molecule and forms an ozone molecule.
Ozone is not transparent to UV (primarily UV-B) light, as such it blocks it. This is important because UV light is harmful to life.

The ozone layer is a region of Earth's stratosphere that contains a high concentration of ozone (O3) molecules. It plays a crucial role in absorbing the majority of the sun's ultraviolet (UV) radiation, thus protecting life on Earth from harmful effects such as skin cancer, cataracts, and damage to crops and marine ecosystems.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
