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.
From largest to smallest, Earth’s atmosphere composition contains nitrogen, oxygen, argon, CO 2, and trace gases. Because water vapor is highly variable geographically, it’s excluded from this total.
13 Μαΐ 2024 · That is essentially what the Earth’s atmosphere is like: layers upon layers of gas surrounding the Earth, working to protect the planet. We asked Rei Ueyama , an atmospheric scientist at NASA Ames Research Center, to explain a little bit more about the function and importance of our atmosphere.
19 Οκτ 2023 · Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.
Composition of the atmosphere. The Earth’s atmosphere is the relatively thin layer of gases surrounding the planet. The atmosphere is held close to Earth by gravity, but the higher you go...
Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in atmospheric layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
There are several unique layers in Earth's atmosphere. Each has characteristic temperatures, pressures, and phenomena. We live in the troposphere, the layer closest to Earth's surface, where most clouds are found and almost all weather occurs.
