Detailed explanation-1: -Gravel are the largest particles in soil and clay are the smallest. Most soil is really only half mineral. The rest is air, water and some organic animal and plant residue.
Detailed explanation-2: -Sandy soil has the largest particles among the different soil types. It is dry and gritty to the touch. The particles have huge spaces between them and so it can’t hold on to water.
Detailed explanation-3: -Sand ranges from 0.05 to 2.0 mm. Particles larger than 2.0 mm are called gravel or stones.
Detailed explanation-4: -The largest soil particle is sand. Sand is a weathered rock and water easily passes through these particles. Silt is a little smaller than sand and is able to hold some water and is similar in texture to flour. Clay is made up of fine grains and does not allow for the circulation or movement of water.
Detailed explanation-5: -Sandy soil: Sandy soil contains mainly sand particles. It has larger particles with larger spaces between them, and they are filled with air. So it is called as well-aerated soils.
