Responses
higher oxygen levels
higher carbon dioxide levels
higher methane levels
higher nitrogen levels
higher carbon dioxide levels
higher methane levels
During the Eocene period compared to the present, a likely difference in atmospheric composition would include:
1. Higher carbon dioxide levels: During the Eocene period, carbon dioxide levels in the atmosphere were significantly higher than they are today. This increase in carbon dioxide is believed to be one of the factors contributing to the warmer climate during that period.
2. Higher methane levels: Methane is another greenhouse gas, and it is likely that methane levels were also higher during the Eocene period compared to the present. Methane is known to have a stronger greenhouse effect than carbon dioxide, so higher levels of methane would further contribute to the warming of the climate.
Please note that higher oxygen and nitrogen levels are not typically considered as likely differences in atmospheric composition during the Eocene period compared to the present.
