The first atmosphere, during the Early Earth's Hadean eon, consisted of gases in the solar nebula, primarily hydrogen, and probably simple hydrides such as those now found in the gas giants (Jupiter and Saturn), notably water vapor, methane and ammonia.
The Earth’s atmosphere is made up of many different gases. At the lower levels, nitrogen and oxygen are the most abundant gases. One of the most important things to remember about Earth’s atmosphere is that it is dynamic, meaning what we see today may not be the same as what we see years from now.
25 Οκτ 2024 · Earth is surrounded by a relatively thin atmosphere (commonly called air) consisting of a mixture of gases, primarily molecular nitrogen (78 percent) and molecular oxygen (21 percent).
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.
air, mixture of gases comprising the Earth’s atmosphere. The mixture contains a group of gases of nearly constant concentrations and a group with concentrations that are variable in both space and time.
23 Ιουλ 2023 · What is Earth's atmosphere made of? Earth's atmosphere is made of mainly nitrogen (~78%) and oxygen (21%), with trace amounts of other gases such as argon, water vapor, carbon dioxide, methane ...
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.
