According to heat conductivity

A. Sand > Loam > Clay > Peat

B. Peat > Sand > Clay > Loam

C. Clay > Peat > Sand > Loam

D. None of the above

Answer: Option A

Solution(By Examveda Team)

The soil thermal conductivity is the ratio of the magnitude of the conductive heat flux through the soil to the magnitude of the temperature gradient.
According to heat conductivity soils can be classified as : Sand > Loam > Clay > Peat.
The soil thermal conductivity of sandy soil is maximum and the lowest is for Peat soil.
