Silicate weathering The weathering page needs to treat silicate weathering Could those who know add a few words about this Silicate weathering is a global sink for CO2 During global ice ages across geological time silicate weathering is reduced when ice sheets reduce the amount of continental crust exposed to weathering The resulting rise in atmospheric C02 is thought to be one factor for bringing the earth out of an ice age and of course setting us up for the next cycle Is there an exemplary illustrative chemical reaction here as with carbonates Thanks in advance
