Web- Sand: soil particle between .05 and 2.0 mm in diameter - Silt: soil particle between .002 and .05 mm in diameter - Clay: soil particle less than .002 mm in diameter Sand is the largest mineral particle and it has more pore space between its particles than silt or clay. Silt particles are smaller than sand, but larger than clay particles. WebSoil porosity is the term used to describe the amount of open space or pore space that can be found between particles of soil. Pore spaces can be formed in a number of ways. For example: Insects and worms in the soil can cause pore spaces. Gases can be trapped in the spaces by groundwater, and this can cause further expansion.

WebSoil is a mixture of rocks, minerals and organic matter. Porosity is also a property of soil.
