The atmosphere is made up of a mixture of gases, mostly nitrogen, oxygen, argon and carbon dioxide. It reaches over 500km above the surface of the planet. There is no exact boundary between the atmosphere and outer space. Atmospheric gases become thinner the higher up you go.The atmosphere just keeps getting less and less dense, until it "blends" into outer space.The atmosphere is divided into four layers based on temperature: the troposphere, stratosphere, mesosphere, and thermosphere
