What is the composition of the atmosphere on Earth?
The Earth's atmosphere is composed mainly of nitrogen (about 78%) and oxygen (about 21%). It also contains a small amount of rare gases such as argon (approximately 0.93%) and carbon dioxide (approximately 0.04%), as well as other substances, such as vaporized water, ozone and carbon monoxide.
There is also a variable amount of dust and pollutants in the atmosphere, which can have adverse effects on health and the environment.
In summary, the exact composition of the atmosphere can vary depending on altitude and geographical location, but it is mainly composed of gases such as nitrogen, oxygen, argon and carbon dioxide. , as well as a variety of gaseous and particulate substances.
What is the composition of the atmosphere on the Moon?
The Moon does not have a significant atmosphere. Indeed, the atmospheric pressure on the surface of the Moon is about 100,000 times lower than on Earth, which means that there is practically no gas around the Moon.
There were emissions of gases from the surface of the Moon during certain volcanic eruptions billions of years ago, but these gases escaped into space or solidified, and therefore there is no more atmosphere on the Moon.
There are some traces of gases in the environment near the Moon, such as helium and hydrogen, which mainly come from the Earth and the Sun, but these quantities are extremely small and do not form a worthy atmosphere. of this name. In summary, the Moon does not have a significant atmosphere.
What is the composition of the atmosphere on Venus?
The atmosphere of Venus is mainly composed of carbon dioxide (about 96%), nitrogen (about 3%) and traces of sulfur dioxide, water vapor and other substances. The atmospheric pressure on the surface of Venus is about 90 times that of Earth, making it similar to that found underwater at a depth of 1000 meters.
Venus also has a layer of sodium sulfide clouds that sits about 50 km above the planet's surface, which contributes to the high density of Venus' atmosphere.
In summary, the atmosphere of Venus is mainly composed of carbon dioxide and nitrogen, with traces of sulfur dioxide, water vapor and other substances. It is also very dense due to the high atmospheric pressure on the planet's surface.
What is the composition of the atmosphere on Mercury?
Mercury has a very small atmosphere, also known as the exosphere, which is mostly made up of sodium, calcium, and potassium. These elements are present in the form of dust and fine particles that have been ejected from the surface of the planet by the bombardment of meteors and solar particles.
There is also oxygen and carbon dioxide in Mercury's exosphere, but in very small amounts. Atmospheric pressure on Mercury's surface is about 100,000 times lower than on Earth, which means there is virtually no gas around the planet.
In summary, Mercury's atmosphere is very weak and composed mainly of sodium, calcium and potassium in the form of dust and fine particles, with very small amounts of oxygen and carbon dioxide.
There is also a variable amount of dust and pollutants in the atmosphere, which can have adverse effects on health and the environment.
