What is specific surface? Why it is more in clay than sand

Specific surface area (SSA) is a property of SOLIDS defined as the total SURFACE AREA of a material per unit of MASS(with units of m/kg or m/g) or solid or bulk volume. Soil's specific surface area (s, m^2/g) depends on shape of soil particle.
