There are three primary components of soil ("dirt"): Sand, Silt, and Clay.
A magnet can pick up tiny iron particles that are in sand.
sand is just really tiny particles of rocks, so the colour of the sand is the colour of the original rock it came from.
Tiny pieces of rock are called 'grains' or 'particles'. These small fragments of rock can vary in size from sand grains to silt or clay particles.

Sand dollars eat tiny particles of food that float in the water, such as plankton.It feeds off the bottom of the sea on plankton.
Sand is made of small pieces of broken rock and mineral particles, while iron filings are tiny pieces of iron metal. Both sand and iron filings are examples of solids, which are composed of tightly packed particles.
Sand is a solid, made up of tiny particles of rocks and minerals. It does not flow like a liquid or disperse like a gas.
A tiny piece of sand is called a grain of sand.
The tiny pieces formed from the weathering of rocks are called sediment or sedimentary particles. These particles can vary in size, from fine clay and silt to coarser sand and gravel, depending on the type of rock and the weathering process.
