Atmospheric Layers and Their Properties

The video lecture explores the structure of the atmosphere, dividing it into three categories: composition, temperature, and function. The composition section discusses the homosphere and heterosphere, focusing on gas mixing. The temperature section covers the troposphere, stratosphere, mesosphere, and thermosphere, explaining temperature changes with altitude. The function section highlights the ozonosphere's role in UV protection and the ionosphere's electrical properties.

What are the three main categories used to divide the structure of the atmosphere?

• Density, Pressure, Humidity
