Answer for screen readers
The final answer is D) High swelling and shrinkage potential.
More Information
Montmorillonite is known for its high swelling and shrinkage potential due to its ability to absorb water. This characteristic is mainly due to the presence of exchangeable cations and water molecules that facilitate its expansion.
Tips
A common mistake is to confuse montmorillonite with other clay minerals like kaolinite, which do not exhibit significant swelling properties.
