The atmosphere of Earth is the planetary atmosphere of Earth, 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.
May 13, 2024 · Learn about the five layers of Earth's atmosphere, how they protect the planet, and what processes occur within them. Find out how atmospheric scientists study greenhouse gases, pollution, and cloud-related phenomena.
Oct 19, 2023 · Learn about Earth's atmosphere, its composition, layers, and functions. Find out how the atmosphere affects weather, climate, and life on Earth.
Oct 2, 2019 · Learn about the five major layers of Earth's atmosphere, from the troposphere where weather and clouds occur, to the exosphere where satellites orbit and the geocorona extends. Find out how temperature, pressure, and density vary with altitude and what phenomena are found in each layer.
The composition of Earth's atmosphere is determined by the by-products of the life that it sustains. Dry air (mixture of gases) from Earth's atmosphere contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and traces of hydrogen, helium, and other "noble" gases (by volume), but generally a variable amount of water vapor is ...
Jul 23, 2023 · Earth's atmosphere is a thin band of air made up of numerous layers based on temperature. Without this protective blanket, life on Earth would not exist as it protects us from heat and...
Jun 3, 2024 · Learn about the atmosphere, the gas and aerosol envelope that extends from Earth's surface into space. Explore the evolution, composition, structure, and processes of the atmosphere, and how they affect climate and life on Earth.
