The soil is formed by weathering, it is the process of breaking down of rocks by the action of heavy wind, water flow and climate. Breaking down of small particles of rocks mix with humus, make it soil fertile. Thus, the correct option is D.

Strong winds, flowing water and heating and cooling of rocks leads to its breakdown. They break the tough rock particles and convert them into smaller ones. They also create cracks in them.

A soil profile is a vertical section of soil that displays its various layers, known as horizons. The primary horizons are typically classified as topsoil (A-horizon), subsoil (B-horizon), and parent material (C-horizon).

Soil is mainly formed due to the weathering of large rocks. The action of abiotic factors on the rocks leads the gradual conversion into the layer of soil. The process of soil formation is known as pedogenesis. Soil is the mixture of minerals, organic matter, gasses, liquids, and the countless organisms that together support life on the earth. The mineral riches of soil provides fertility to the soil and hence, help the plants to grow well. 

The soil is mainly formed by the process of pedogenesis. The abiotic factors constantly act on the rocks and lead to the formation of soil by weathering.

Soil formation is a complex process influenced by multiple factors including climate, organisms, parent material, topography, and time. All these factors interact to develop the soil structure.

Weathering is the physical and chemical breakdown of rocks, while pedogenesis is the broader process of soil development. Both are integral to the creation of soil.

Broad leaf corresponds to deciduous forest, growing squabble (likely a typo for social forestry/afforestation context) matches social forestry, soil erosion is caused by deforestation, and silviculture is the practice of afforestation.

Rain, wind, ice and temperature changes break the tough, hard parent material or rocks. This process is very slow but it steadily continues. Such broken parts are further withered by same factors as well as some other factors as acids etc. Therefore, wind, water and the Sun are involved in soil formation. 

Polythene bags are not involved in soil formation. However, plastic bags are threat to environment, because these bags are non-degradable, i.e., do not decay and thus, do not lead to soil formation.
