Volcanoes expel gases with chemical compositions which closely match the ratios of non-photosynthetic gases in air.
Earth's first atmosphere was likely formed through volcanic activity, which released gases such as water vapor, carbon dioxide, and nitrogen. The oceans were then formed over time as water vapor in the atmosphere condensed and fell as rain, eventually filling depressions on the Earth's surface to form oceans.
Earth's present atmosphere is believed to have originated from volcanic activity early in the planet's history. Volcanoes released gases such as water vapor, carbon dioxide, and nitrogen, which eventually formed the atmosphere over billions of years.
The Earth's atmosphere began forming approximately 4.5 billion years ago during the Hadean Eon, following the planet's formation. This initial atmosphere was likely composed of gases released from volcanic activity and impacts from comets and asteroids.
The era that began with the formation of Earth's atmosphere is the Hadean Eon, which lasted from about 4.6 to 4.0 billion years ago. This was a time when Earth was still forming and experiencing intense volcanic activity, leading to the formation of the early atmosphere.
The formation of oceans on Earth likely occurred as a result of the cooling and solidification of the Earth's surface. Water vapor that was present in the atmosphere condensed and formed liquid water, eventually collecting in low-lying areas to create oceans. The process was also influenced by volcanic activity releasing water vapor and other gases into the atmosphere.

how do geologists think earths atmosphere is formed
Volcanic (Extrusive) igneous rock, which are formed by lava that comes out of the earths crust, then cools and solidifies rapidly on the earths surface due to exposure to the environmental atmosphere.

Earth's first atmosphere was likely formed through volcanic activity, which released gases such as water vapor, carbon dioxide, and nitrogen. The oceans were then formed over time as water vapor in the atmosphere condensed and fell as rain, eventually filling depressions on the Earth's surface to form oceans.
The first atmosphere on Earth was primarily formed through volcanic outgassing, which released gases such as water vapor, carbon dioxide, and nitrogen. These gases accumulated around the planet and eventually formed the primitive atmosphere.
It was about 4 billion years ago, that the Earths oceans formed

The earth's atmosphere is very old. It was formed when earth was formed.
The formation of oceans on Earth likely occurred as a result of the cooling and solidification of the Earth's surface. Water vapor that was present in the atmosphere condensed and formed liquid water, eventually collecting in low-lying areas to create oceans.
