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.
• Electrostatic forces: Strong electrical charges pull the particles close to each other.

Explanation

• In fluvial processes, small and shallow channels are called rills, which grow into gullies,

Additional information

• Valleys: Large, low-lying areas drained by rivers or streams.
• Deltas: Landforms created at the mouth of a river where it meets standing water.
• Levees: Raised ridges of sediment running along the banks of a river channel.

• The age of a tree is determined by its Rings (Number of Annual Rings).
• Each annual ring generally represents one year of growth.
• Counting the rings on the trunk helps determine the tree's age.
• The study of tree rings is called Dendrochronology.

Explanation

• Protists are simple, mostly unicellular organisms.
• Algae show plant-like characteristics among protists.
• They contain chlorophyll for making food.
• They produce their own food through photosynthesis.
• That is why they are called plant-like protists.
