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.

Air is made up of a mixture of different gases. The principal constituents of Earth’s atmosphere are: 1. Nitrogen – about 78% of the atmosphere 2. Oxygen – about 21% 3. Argon – about 1% As well as these, there are various trace gases at relatively low concentrations measured in parts per million (ppm; 1ppm = 0.0001%) 1. Carbon dioxide – about 416 p...
The Earth’s atmosphere is divided into several layers, defined according to changes in temperature with altitude. The boundaries between the layers are not precisely fixed, but can vary somewhat.
The Earth’s atmosphere has not always had the same composition as today. Early in its history, Earth’s atmosphere would have been quite alien to us. After the Earth formed it was subject to bombardment by asteroids and other celestial bodies. Once this ended and the planet stabilised, the first proper atmosphere would have been dominated by gases f...
The atmosphere is a mixture of gases. The atmosphere is mostly nitrogen (approximately 80%) and oxygen (approximately 20%). The remaining gases are found in much smaller proportions, such...
May 13, 2024 · Outgoing radiation is longwave radiation emitted by Earth’s surface, which is almost entirely absorbed by atmospheric gases and then re-emitted in all directions: some gets launched into space and is therefore lost from the system, but some goes back down to Earth to repeat the warming cycle.
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.
Some of the atmosphere's gases, like carbon dioxide, are particularly good at absorbing and trapping radiation. Changes in the amounts of these gases directly affect our climate. Gases in Earth's Atmosphere.
Jan 21, 2023 · The gases ozone, water vapor, and carbon dioxide are only minor components of the atmosphere, but they exert a huge effect on the Earth by absorbing radiation in the ranges indicated by the shading. Ozone in the upper atmosphere filters out the ultraviolet light below about 360 nm that is destructive of life.
