water and nutrients.

Sand: the largest grain size, or sediment piece, that makes up soil. It feels gritty.
Sediment: the pieces of rocks and minerals that are created by weathering.
Silt: the grain size, or sediment piece, that is smaller than sand but larger than clay. It feels like flour.
Soil: a mixture of water, air, sediments (minerals), and humus that covers most of the Earth’s land
