CO2 dissolves in water in the atmosphere to produce bicarbonate ion (HCO3 and carbonic acid (H*). Carbonic acid reacts with
silicate minerals in rocks in the process of chemical weathering. How are these chemical reactions related to climate?
A. Bicarbonate ion in the atmosphere is a greenhouse gas
B• Chemical weathering releases heat into the lower atmosphere.
c• Chemical weathering adds CO2 to the atmosphere when bicarbonate ion reacts with minerals in rock.
d• Chemical weathering removes CO2 from the atmosphere converting it to bicarbonate ion in the oceans.
