The answer is true. Climate plays a vital role in determining the composition and horizon of any type of soil.
There are five factors that determine how soil is formed, and they are climate, the parent material of the soil, the biological features of the soil, the topography, and time.
Soil horizons are layers of the soil that are distinct from other layers of the same soil, both in the physical and the chemical composition of the soil. They can be divided into three: the surface, subsoil, and substratum horizons.
They both contribute greatly to determining soil composition.
