Layers of the Earth's Atmosphere - Facts with Diagram
2023年10月6日 · Scientists divide the atmosphere into 5 different layers based on factors like air pressure and density. The names of these layers, in order of lowest to highest, are: 1. Troposphere. Temperature: 62°F (17°C) around the lowest point to -60°F (-51°C) near the top. The troposphere is the lowest layer of the atmosphere, and it is where we live.
