carbon dioxide and nitrogen.
Venuses atmosphere is extremely thick
atmosphere
Any gas or group of gases can make a thin atmosphere.
The two main gases that make up the atmosphere of Uranus are hydrogen and helium. The atmosphere also contains ammonia and methane.
Venus's atmosphere is primarily composed of carbon dioxide, making up about 96.5% of its atmosphere. It also contains nitrogen (around 3.5%) and trace amounts of other gases, including sulfur dioxide. This dense atmosphere creates an extreme greenhouse effect, leading to surface temperatures hot enough to melt lead.
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
there is 1.25 percent of inert gases in the atmosphere
Nitrogen (78%) and oyxgen (21%). Argon comprises just under 1%.
Earth's atmosphere is composed of principal two gases. They are Nitrogen and Oxygen. Nitrogen forms 78% of the gas Oxygen form 21% of the gases. This leaves 1% for other gases , such as carbon dioxide, water vapour , the noble gases and trace amounts of methane, sulphur dioxide, hydrogen All these gases go round in cycles. There is a nitrogen cycle. There is an oxygen/carbon dioxide cycle There is a water cycle. The percentages are not static/inert amounts, but vary very slightly.
Nitrogen, Oxygen and Argon make up 99% of the atmosphere
The Earth's atmosphere.
Nitrogen and oxygen make up the largest percentage of the atmosphere.
