Detailed explanation-1: -Silt is made up of rock and mineral particles that are larger than clay but smaller than sand. Individual silt particles are so small that they are difficult to see.
Detailed explanation-2: -The most common types of rock found in gravel are basalt, limestone, and sandstone. Gravel is used in a wide range of industrial and construction applications, from home building to road paving, and come in two types: granular or pebble.
Detailed explanation-3: -The layer of soil which is just below the sub-soil is called C-horizon. It is also called sub-stratum. Sub-stratum is made up of small lumps of broken rocks (or stones) formed by the partial weathering of bed-rock (or parent rock). Below the C-horizon we have unweathered solid rock called bed-rock (or parent rock).
