Soil is the thin layer of material covering the earth’s surface and is formed from the weathering of rocks. It is made up mainly of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly.
What Is Soil and How Is It Formed?
What is soil? Soil is a mixture of organic matter, minerals, gases, liquids, and countless organisms that together support life on Earth. Soil is not just dirt.
It is a complex mixture of minerals, air, water, and organic matter. How is soil formed? Soil is formed over time. The rocks and minerals that make up the Earth’s crust are broken down into smaller pieces by the forces of weathering and erosion.
This process is helped along by the actions of plants and animals. As plants grow, their roots break up rocks and help to form new soil. Animals also play a role in soil formation.
As they move around, they help to mix different types of soil together. What are the different types of soil? There are many different types of soil, but they can be broadly classified into three main types:
sand, clay, and silt. Sand: Sand is the largest type of soil particle. It is made up of tiny pieces of rock, minerals, or shells. Sand is very dry and does not hold onto water or nutrients very well.
Clay: Clay is the smallest type of soil particle. It is made up of very small pieces of minerals that have been
