First, the lightest soil component is clay. The, there's sand then humus then finally gravel.
25%-sand 255-clay 25%-gravel 25%-humus
Gravel is typically heavier than sand, and therefore gravel would be heavier than both clay and sand. This is because gravel consists of larger-sized particles and has a higher density compared to clay and sand.
Top soil usually has humus and minerals which are often absent from sand, clay or gravel.
SAND SAND
yes
Clay is heavier than sand since its density and its moisture content cause it to be heavier.
no
Same
In water, sand will settle first, followed by gravel, and then clay. This order is due to the differences in particle size and density: sand particles are larger and heavier than clay, so they sink more quickly. Gravel, being even larger and denser than sand, also settles quickly. Clay particles are much smaller and lighter, which allows them to remain suspended in water for a longer period before settling.
