What piece of evidence supports the theory that volcanic eruptions formed Earth's early atmosphere? O Volcanoes expel gases with chemical compositions which closely match the ratios of gases in air not caused by photosynthesis.
O Volcanoes are clustered near the equator, so their gas output spreads over Earth's surface.
O Volcanoes expel a mixture of gases consisting almost entirely of water vapor and oxygen
Volcanic eruptions are inversely proportional to local atmospheric pressure.
