Which of the following would increase the rate of diffusion?
◦ decreasing the soil moisture
◦ decreasing the diffusion coefficient
◦ decreasing the tortuosity
◦ increasing the buffer capacity

Question 2

Why does smectite have a higher degree of expansion than vermiculite, in spite of both the clay minerals displaying high CEC?
◦ because, in smectite cations neutralize the (-) charge
between two 2:1 layers
◦ because, in smectite, the tetrahedral charge attracts hydrated cations
◦ because, in smectite, isomorphic substitution occurs in both octahedral and tetrahedral
layers
◦ because, in smectite, isomorphic substitution occurs only in the octahedral layer
