The document summarizes key concepts about the atmosphere. It is composed primarily of nitrogen and oxygen. It describes atmospheric layers from closest to farthest as the troposphere, stratosphere, mesosphere, and thermosphere. The greenhouse effect and global warming are discussed as well as atmospheric heating processes of radiation, conduction, and convection. Wind patterns like trade winds and westerlies are influenced by pressure belts and the Coriolis effect. Air pollution sources include vehicles, power plants, and industries. Secondary pollutants form from chemical reactions between primary pollutants and substances.
