The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by Earth's gravity.

2 paź 2019 · Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Troposphere.
Earth’s atmosphere is bounded at the bottom by water and land—that is, by the surface of Earth. Heating of this surface is accomplished by three physical processes— radiation, conduction, and convection —and the temperature at the interface of the atmosphere and surface is a result of this heating.
Earth's atmosphere profile. The atmosphere of Earth is composed of layers with different properties, such as specific gaseous composition, temperature, and pressure. The troposphere is the lowest layer of the atmosphere. This extends from the planetary surface to the bottom of the stratosphere.
Learn about the atmosphere, a mixture of gases that surrounds the Earth and helps make life possible. Explore the layers, gases, and phenomena of Earth's atmosphere and compare it with other planets and moons.
