By volume, they are oxygen and sodium.
Mercury has a surface pressure that is near enough zero (or a vacuum), the planet holds no real atmosphere due to its small size. There are some trace gases at the surface, but not what one would call a proper atmosphere.
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
it makes it very hot and oncreases the amount of radiation
The greenhouse effect warms the gases in the atmosphere.
there is 1.25 percent of inert gases in the atmosphere
what is being done to show that there are gases in the atmosphere
The mixture of gases in the atmosphere is not considered a solution, suspension, or colloid because gases are uniformly distributed and do not form distinct phases in the atmosphere. It is more accurately described as a homogeneous mixture of gases known as air.
When did people start to change the atmosphere by releasing gases
The atmosphere is composed of gases such as nitrogen (78%), oxygen (21%), argon (0.93%), and trace amounts of carbon dioxide, methane, and other gases. Water vapor is also an important component of the atmosphere.
Three gases in the atmosphere are nitrogen, oxygen, and carbon dioxide.
Mercury has virtually no atmosphere due to its proximity to the Sun and its relatively low gravitational attraction force
