Question

Given below are two statements:
Statement (I): The surface of a 'Pedon' is roughly polygonal.
Statement (II): The surface area of a pedon ranges from 1 m\textsuperscript{2} to 10 m\textsuperscript{2}.

• A. Both Statement (I) and Statement (II) are true.
• B. Both Statement (I) and Statement (II) are false.
• C. Statement (I) is true but Statement (II) is false.
• D. Statement (I) is false but Statement (II) is true.

Hint:

A pedon is a 3D unit for studying soils in the field—both its shape and size are defined.

Answer 1

The Correct Option is A

A pedon represents the smallest unit of soil with all the characteristics of a soil profile. Its surface is generally polygonal, and the area typically ranges between 1 to 10 m².

Answer 2

Definitional check:
A pedon is formally defined in soil science as the smallest three-dimensional body of soil that shows the full range of a soil's horizons and properties, large enough to allow study of horizon boundaries and variability but small enough to be a single sampling unit. Standard references give its lateral surface area as lying between about \( 1\,\text{m}^2 \) and \( 10\,\text{m}^2 \), with the shape approximated as polygonal so that pedons can tile together to form a soil polypedon. Both descriptions match the accepted definition exactly, so both Statement (I) and Statement (II) are true.
