Detailed explanation-1: -Silt particles are from 0.002 to 0.05 mm in diameter. Sand ranges from 0.05 to 2.0 mm. Particles larger than 2.0 mm are called gravel or stones.
Detailed explanation-2: -The particles that make up soil are categorized into three groups by size – sand, silt, and clay. Sand particles are the largest and clay particles the smallest.
Detailed explanation-3: -Sand, silt, and clay are made from different rocks and minerals but the other important difference between them is the size of their particles. Sand has the biggest, clay the smallest and silt is in between.
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: -Conversely, the largest (in terms of mass) fundamental particle we know of is a particle called a top quark, measuring a whopping 172.5 billion electron volts, according to Lincoln.
