Questions: Clays can remain suspended in a water column for decades before setuling due to their small size. True False

The answer is True: Clays can remain suspended in a water column for decades before settling due to their small size.

Explanation:

• Clays are composed of very fine particles, often less than 2 micrometers in size. Due to their small size and low density, they have a very slow settling rate in water.
• The small size of clay particles allows them to remain suspended in water for extended periods, sometimes even decades, especially in calm water conditions where there is little disturbance to promote settling.
• Additionally, clay particles often carry a negative charge, which causes them to repel each other and remain dispersed in the water column rather than clumping together and settling.

In summary, the statement is true because the properties of clay particles allow them to remain suspended in water for long periods.
