What is earths atmosphere is primarily composed of?
the earth first atmosphere is troposphere
Approximately 20 percent of the earths atmosphere is composed of?
oxygen
What is 78 percent of earths atmosphere composed of?
Nitrogen makes up about 78 percent of Earth's atmosphere.
What effects does oxygen have on the earths atmosphere?
Without its oxygen content the Earth's atmosphere would be composed almost entirely of nitrogen and would be chemically inert; oxygen causes the atmosphere to be chemically active (and breathable by humans).
What is the earths atmosphere made of?
The earth's atmosphere is composed as follows:nitrogen: 78%oxygen: 21%argon: 0.9%trace gases make up the remaining less than 0.1% - these include carbon dioxide, neon, helium, methane, krypton, and hydrogen, and the barest amounts of many others
