On which of the following planets is the atmospheric greenhouse effect strongest?

the oxygen molecules in Earth's atmosphere
are a result of life
the main greenhouse gases in the atmospheres of the terrestrial planets are:
carbon dioxide and water
Place in chronological order the following steps in the formation and evolution of Earth's atmosphere.
hydrogen and helium are captured from the protoplanetary disk hydrogen and helium are lost from the atmosphere volcanoes,comets, and asteroids increase the inventory of volatile matter Life releases CO2 from the subsurface into the atmosphere plant life converts carbon dioxide to oxygen oxygen enables the growth of new life-forms
the differences in the climates of Venus, Earth and Mars are caused primarily by
the thickness of their atmosphere
All weather and wind on Earth are a result of convection in the:
troposphere
