Explanation:
The reason for the more concentration of carbon dioxide in the atmosphere of Venus than in the Earth -
On the Earth , most amount of the carbon dioxide is in the ocean water and in sea sediments .
Considering Venus , in the planet Venus , there is no Ocean water , hence , carbon dioxide can not get dissolved into the water , hence , it is found in the atmosphere .
So , the escape velocity for carbon dioxide on Mars is smaller than Venus .
