GEOLOGY

Detailed explanation-1: -However, general usage is as follows ranging from largest to smallest: boulders, cobbles, gravel, sand, silt, and clays. Sediments form from the disintegration of rocks.

Detailed explanation-2: -Starting with the finest, clay particles are smaller than 0.002 mm in diameter. Some clay particles are so small that ordinary microscopes do not show them. Silt particles are from 0.002 to 0.05 mm in diameter. Sand ranges from 0.05 to 2.0 mm.

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: -Explanation: Sand is defined as having a diameter ranging from 0.05 mm to 2 mm, silt as having a diameter ranging from 0.05 mm to 0.002 mm, and clay as having a diameter smaller than 0.002 mm. Therefore, sand particles are the largest, followed by silt, and then clay being the smallest particles in the spectrum.

Detailed explanation-5: -Clay is the category of clastic sediment with the smallest particle size. Clastic sediments are classified in terms of their particle or grain size. Clay is at the bottom of the size classification with particles ranging from 0.00006 millimeters in diameter to 0.0038 millimeters in diameter.
