Importance of Clay Minerals:The clay minerals and soil organic matter are colloids.The most important property of colloids is their small size and large surface area. The total colloidal area of soil colloids may range from 10m2/g to more than 800 m2/g depending the external and internal surfaces of the colloid.Soil colloids also carry negative or positive charges on their external and internal surfaces. The presence of charge influences their ability to attract or repulse charge ions to or from surfaces.Soils colloids play a very important role in the chemical reaction which take play in soil and influence the movement and retention of contaminants, metals, and nutrients in the soil.

What do feldspars weather into?
Clay minerals.
Are clay minerals made of sheet silicates?
Clay minerals structure themselves in sheets or layers, and are silicate minerals. This characteristic makes clay feel slippery when wet, as the flat individual mineral grains easily slide in a parallel fashion from one another.
Why do clay minerals change to mica in the metamorphism of shale?
Because it does,that the main reason jkThe mild heat and pressure that changes clay into shale causes the minerals in the clay to align and compress into more crystalline layers, ie. mica.
What are the cohesive and cohesionless soils and how thr are differe from each other?
Cohesive soil contains high clay minerals whereas cohesionless contains less clay minerals. source:engineeringmad.com
What happens to plagioclase feldspar when it is weathered?
It forms clay minerals.
Clay most likely was involved in which process?
Clay is made up of clay minerals, and clay minerals are chemically weathered from minerals such mica and felspar.
