The most common types of soil are clay, loam, sand, silt and gravel. Clay is a sticky soil that holds water well, while loam is a combination of sand and silt. Sand is made up of tiny particles that are easily moved around by wind and water, while silt is smaller than sand but larger than clay. Gravel is made up of large particles that are not as easily moved around.
