Question

select \yes\ if the gasses present in earths early atmosphere most important to the development of the atmosphere, hydrosphere and biosphere. select
o\ if they were not
water vapor
methane
hydrogen
hydrogen sulfide
carbon dioxide
nitrogen

Explanation:

Water vapor is crucial for the hydrological cycle and formation of clouds and precipitation, important for the hydrosphere and biosphere. Methane is a greenhouse - gas and played a role in early Earth's climate and biogeochemical cycles. Hydrogen was present in early atmosphere and involved in chemical reactions. Hydrogen sulfide was used by some early life - forms in chemosynthesis. Carbon dioxide is vital for photosynthesis and the carbon cycle. Nitrogen is a key component of proteins and nucleic acids and is part of the nitrogen cycle. All these gases were important in the development of the atmosphere, hydrosphere, and biosphere.

Answer:

Water vapor: YES
Methane: YES
Hydrogen: YES
Hydrogen Sulfide: YES
Carbon Dioxide: YES
Nitrogen: YES
