Aire-1

The video tutorial explains the concept of air as a mixture of gases that form Earth's atmosphere, essential for life. It covers the composition of air, including nitrogen, oxygen, and carbon dioxide, and the role of gravity in maintaining the atmosphere. The tutorial describes the four layers of the atmosphere: troposphere, stratosphere, mesosphere, and thermosphere, and their characteristics. It concludes with a reflection on why there is no air in space.
