Oxygen
There is a bit of confusion here. The Main gas of the atmosphere of Venus, carbon dioxide, is also the main gas of the atmosphere of Mars. This gas is a minor component of Earth's atmosphere.
The main component of Earth's original atmosphere was likely hydrogen and helium. Over time, these gases were largely lost to space, and the atmosphere evolved to primarily consist of nitrogen and oxygen as a result of volcanic outgassing and the development of life on Earth.
Oxygen is a component of the Earth's atmosphere. It makes up about 21% of the air we breathe.
The main component of Earth's ancient atmosphere was likely carbon dioxide (CO2), which was released by volcanic activity. Over time, photosynthetic organisms like cyanobacteria helped to transform CO2 into oxygen through the process of photosynthesis, leading to the development of Earth's current atmospheric composition.
Yes
yes , that all component that make up the atmosphere of earth
Nitrogen is the largest component of Earth's present atmosphere, making up about 78% of the total gases in the atmosphere.
The gaseous part of the Earth is called the atmosphere. The solid portion of Earth is the geosphere, and the hydrosphere is the Earth's water component.
these ??? There are no choices to choose from.
Oxygen is the primary component, making up about 21% of Earth's atmosphere.
The atmosphere of the Earth is primarily nitrogen, which is about 78% of air by volume. Nearly 21% is oxygen, 1% is argon, and the remainder consists of trace gases and carbon dioxide.
Yes, the principal gas in the Venusian atmosphere is carbon dioxide (CO2). It is also a minor component of Earth's and Mars' atmospheres, though nitrogen (N2) dominates in Earth's atmosphere and argon (Ar) is more abundant in Mars' atmosphere.
