Topsoil is the loose weathered material on Earth's surface in which plants can grow. It is a mixture of minerals, organic matter, water, and air, providing essential nutrients and support for plant growth.
The loose material is called sediment. It may include bits of rock, minerals, and organic material like plant and animal remains. This sediment can accumulate in layers over time and eventually become sedimentary rock through processes like lithification.

These layers differ in their composition, structure, and nutrient content, impacting plant growth and water filtration.
