What are the three main types of soil?
Soil is made up of minerals, organic matter, water, and air. Soil can be divided into three main types: sand, silt, and clay. The type of soil influences how plants grow and the types of plants that can grow in the soil.
Types of Soil
Soil Type: Soil type is the makeup of the soil, determined by the different types of particles that make up the soil. It can be composed of sand, silt, clay, or organic matter. Soil Texture: Soil texture is the size of the particles in the soil, such as sand, silt, and clay. It affects how easily water and air can move through the soil. Soil Structure: Soil structure is the arrangement of the soil particles. It affects how easily water and air can move through the soil and how easy it is for the roots of plants to grow.
Concepts:
Different types of soil can exist in the same area, and they can even be mixed together to create new soils. Soil is made up of particles from rocks and minerals, and can also contain organic matter like decaying plants and animals. Soil can move from place to place due to wind, water, and mechanical forces like plants, animals, and humans.
