Explanation

• Soil with a particle size less than 0.002 mm and high cohesion is called clay.
• It feels sticky when wet, holds a lot of water, and hardens when dry.

Explanation

• The strength of clay is mainly due to cohesion 

Why Clay Has High Cohesion

• Tiny particles: Clay particles are microscopic and flat, like tiny plates.
• Water films: Water molecules stick between these tiny plates.
