Answer 2

Answer:

B horizon is rich in minerals.

The term "subsoil layer" also applies to horizon B. It has a light brown hue. Its inside is filled with minerals like iron and clay. The plant roots can access the maximum amount of soluble minerals and clay for their growth and development because this layer includes more of these materials.

Explanation:

• A soil horizon is a layer that is parallel to the soil surface and has different physical, chemical, and biological properties from layers above and below. In many instances, horizons are determined by evident physical characteristics, primarily color and texture.
• These can be characterized both in absolute terms (such as the particle size distribution for texture) and in terms of the material's proximity to them, such as "coarser" or "sandier" than the horizons above and below.
• Symbols, most often utilized in a hierarchical manner, are used to denote the recognized horizons. Capital letters are used to denote master horizons (principal horizons).
• The master vistas are further distinguished by suffixes, which take the shape of lowercase letters and numbers. The world has a wide variety of horizon sign systems.
