The outermost layer of the atmosphere is

The answer is: exosphere

The layers of the atmosphere are considered a protective barrier that protects the planet from many external dangers, and this atmosphere includes several different layers, including the most distant layer from Earth, which is the last layer in the atmosphere, known as the “exosphere”. This layer is characterized by a low concentration of gases and extends to the highest possible level of the atmosphere until it reaches the borders of outer space. The exosphere plays an important role in protecting the Earth from harmful rays and radioactive charges, thus making the life of living organisms on Earth safe and sustainable.
