Question

Two soil samples A and B, each weighing 75 g are heated over a flame for few minutes. When the weights of soil samples are checked afterwards, sample A weighs 60 g whereas sample B weighs 68 g. Which of the samples could be sandy soil and which clayey soil? Give reasons for your answer​

Answer 1

Explanation:

Correct option is

B

Y is a mixture of sand, silt and appropriate amount of clay.

Sand has very little capacity to hold water as it has large particles and the nutrient amount is minimum.

Silt with medium particles in size retains a moderate amount of water.

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'.
