Question

Sandeep has three soil samples X, Y and Z, each with weight 50 g. 100 mL of water is poured drop by drop with the help of a dropper on all the soil samples. The given graph shows weight of water absorbed by each soil samples.
Select the correct option regarding the soil samples.

• A. X is a mixture of sand, silt and a good amount of clay.
• B. Y is a mixture of sand, silt and appropriate amount of clay.
• C. Z is a sandy soil with very little clay.
• D. Z is a mixture of clay and slit with higher amount of sand.

Answer 1

The correct option is B Y is a mixture of sand, silt and appropriate amount of clay.

1. Sand has very little capacity to hold water as it has large particles and the nutrient amount is minimum.
2. Silt with medium particles in size retains a moderate amount of water.
3. Clay which has fine and small particles so it holds the good or maximum amount of water.

• In X the water holding capacity is very less means it contains the highest amount of sand.
• In Y a mixture of sand, silt and an appropriate amount of clay are present.
• In Z clay is present in the highest amount so it holds the maximum amount of water.

So the correct option is 'In Y a mixture of sand, silt and an appropriate amount of clay'.
