Layers of the Earth's Atmosphere - Facts with Diagram
2023年10月6日 · The atmosphere of the earth is the layer of gases (commonly called air) that surrounds the earth and creates an inhabitable environment, maintains temperature, causes weather, and protects its inhabitants from solar radiation. Scientists divide the atmosphere into 5 different layers based on factors like air pressure and density.
Atmosphere of Earth - Wikipedia
Several layers can be distinguished in the atmosphere based on characteristics such as temperature and composition, namely the troposphere, stratosphere, mesosphere, thermosphere (formally the ionosphere) and exosphere.
Layers of Earth's Atmosphere - Center for Science Education
Earth's atmosphere is composed of a series of layers, each with its own specific traits. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

2024年11月15日 · Atmosphere, the gas and aerosol envelope that extends from the ocean, land, and ice-covered surface of a planet outward into space. The density of the atmosphere decreases outward, because the planet’s gravitational attraction, which pulls the gases and aerosols inward, is greatest close to the surface.
