ok on the old cars and trucks it was 60 % of the braking was done by the front brakes now its 50-50
the front are the main ones because as the brakes are applied the weight is forced to the front. Most vehicles are designed for a 60/40 system where the front has 60% of the breaking,
Plants and trees. Plants and trees take in carbon and release oxygen.
I'm not sure what the third one is but Plants and trees absorb CO2 in a process known as Photosynthesis. The Oceans also remove CO2 from the atmosphere.
1) creation and burial of hydrocarbons and coal 2) plant growth 3) creation of carbonate rocks like limestone and dolomite.
