The earths first atmosphere was created by the methane, carbon dioxide, sulphur oxides and water vapor that volcanoes were pumping out. Oxygen started to come in noticeable quantities once life had formed. Nitrogen is inert, so doesn't do anything.
Oxygen Please study this, & don't forget it so you don't have to keep looking up answers .
Because of descending air ( warm air ) which means it picks up water from the atmosphere, rather than releasing it through condensation.The lack of condensation means that few clouds are formed.
The Extrusive igneous rock is formed on the earths surface while the Intrusive igneous rock is formed within or inside the earths crust.
its by condensation where there is heat and it hits cold .
how do geologists think earths atmosphere is formed
The earth's atmosphere is very old. It was formed when earth was formed.
There was an ozone atmosphere on primitive Earth, but not an ozone layer which was formed further on. The primitive atmosphere on the surface of the Earth mostly composed by ozone was pushed upwards by the oxygen formed by dead organisms. That primitive ozone atmosphere on the surface of the Earth protected the forming microorganisms from the UV radiation. JamesWest09
Hydrogen and helium
The earths atmophere came from your mom!
Evaporation, condensation & precipitation from clouds formed by the first action.
Precipitation is rain, sleet, snow or dew formed by condensation of water vapour in the atmosphere
The process that most directly results in cloud formation is Condensation. When condensation is formed, it evaporates into the atmosphere and forms clouds. Most people don't know this, but clouds are actually formed completely from rain, not water vapor. :} The last statement about clouds being formed from strictly rain is incorrect. Clouds are formed from water vapor.
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.
plato:the primitive organic molcules were formed inan oxidizing atmosphere in the primordial soup
a volcano is formed when the plates hit each other.
At high altitudes a "contrail" or condensation trail is formed due to the combustion from the engines. Whether or not they form depends entirely on atmosphere conditions.
