Sand has particles that are easily seen and felt. They grate against one another when rubbed together.

Clay particles are too small to be seen or felt, but when moist, clay looks and feels a lot like modeling clay. When you rub clay between your fingers, it usually leaves a smear on the ends of your fingers.

Silt particles are too small to be seen with the naked eye and have a smooth feel.
