As CEC of soil can be maintained by the type of caution exchange from soil like Na, K, thus decrease of H+ ions increase the variable charges and thus increasing the capacity, Histosols, Mollisols, and vertisols have a high CEC order. And clay consists of roughly composed chlorite, kaolinite, and most of soil humus.
James Hutton Along with Charles Lyell, James Hutton developed the concept of uniformitarianism. He believed Earth's landscapes like mountains and oceans formed over long period of time through gradual processes.
