Question

The fresh leaves and recognisable litter are found in water of the following horizon of soil?
A. A-horizon
B. B-horizon
C. C-horizon
D. O-horizon

Answer 1

Hint: The majority of land is covered in loose surface material called soil. It is made up of organic as well as inorganic materials. Being a source of water and nutrients, soil also gives agricultural plants the structural support they need to grow. During the process of formation, the soil is structured in layers or horizons.

Complete step by step solution:
The American Soil Science Society provided this definition. The unconsolidated mineral or organic material that makes up the immediate surface of the Earth and acts as a natural substrate for terrestrial plants to thrive is known as soil.
The soil profile refers to these horizons or strata. A soil pit exposes the vertical portion of the soil in this area. The color and size of the soil particles make it simple to identify the different soil layers. Subsoil, parent rock, and topsoil are the different soil layers.
The qualities of soil vary depending on its stratum. The function of the soil is also determined by the soil profile. Based on characteristics like the given soil sample's color, texture, structure, thickness, and chemical makeup, one can distinguish it from other soil samples.
The nutrients contained in this detritus, or dead organic waste, are added to the soil's top layer, also known as the litter layer or O horizon ("O" for "organic").
So, option (D) is correct.

Note:
Layers of soil are present, and they are organized when the soil is formed. The order of these layers, which are referred to as horizons, makes up the soil profile. The color and size of the soil's particles make it simple to identify the different soil layers. The parent rock, the topsoil, and the subsoil are the three primary layers of soil.
