Possibility of chemical weathering before the advent of vascular land plants

Possibility of chemical weathering before the advent of vascular land plants

A study found that a low level of microbial respiration may be sufficient to support appreciable carbon dioxide concentrations in the vadose zone because of a slow rate of carbon dioxide loss to the surface. It is argued that the vadose zone exerts a strong influence on the carbon dioxide concentrat...
