Solution
Clay Soil Clay particles commonly are platy in shape and highly plastic when moist. It exhibits properties like flocculation, deflocculation and plasticity.
=> The size of clay particle is < 0.002 mm.
Specific heat is higher
Soil moisture is measured by

Solution
Red Soil Red colour in red soil is due to presence of various oxides of iron. Their main features are a light texture, absence and low soluble salts. They are slightly acidic to neutral in reaction, the pH from 6.0 to 7.5. Red soil is found in Chennai, Madhya Pradesh, Andhra Pradesh, Uttar Pradesh, Bihar, Odisha etc.

The typical soil derived from decan trap is called regur or black cotton soils. It is highly argillaceous, very fine grained and dark and contains a high proportion of Ca and Mg carbonates.
The thermal conductivity of heavy soils with high organic matter will be
The moisture content in soil increases, the thermal conductivity soil
