Answer 1

Factors Responsible for the Formation of Soil
The relief features, parent material, climate, vegetation and other life-forms as well as time apart from human activities are the major factors responsible for the formation of soil.
1. Parent Material: It is deposited by streams or derived from in-situ weathering. In this stage, soil inherits many properties like the mineral composition, the colour, the particle size and the chemical elements. For example- Black soil derived its colour from lava rock
2. Climate: It is one of the important factors in the formation of soil because it affects the rate of weathering of the parent rock.

Answer 2

1. Soil is formed under the influence of a number of factors:

• Parent material: It is responsible for the color, texture, and constituents of soil.
• Climate: The temperature and humidity are responsible for the composition of minerals and organic content in the soil.
• Biota: The living organism present is responsible for speeding up the process of soil formation.
• Topography: The steepness of the slope and the aspect i.e the side facing the slope are responsible for soil formation
• Time: As time passes, the climate and vegetation act on topography and parent material and change it into the soil.

2.

• Alluvial soil is depositional in nature with rich content of Potassium. The soil particles have an adequate proportion of sand, silt, and clay which helps in moisture retention.
• The plant growth is promoted in this way. So, it is considered as the best soil for agriculture purpose.
• It is usually found in the Gangetic region and near the deltas of major rivers.

3.

• Alluvial soils are formed by the deposition of soil particles carried by the river during its course to the sea.
• The deposition takes many years for the accumulation of soil and forming the thick layer which is suitable for crops like paddy, wheat, and sugarcane.

4.

• Transported soils are formed by the material which is eroded from the underlying rocks and carried to a greater distance where they are accumulated over time. Alluvial soils are such types of soils.
• Sedentary soils are formed from the rocks which are underlying it. Forest soils are an example of such soils.

5.

• Forest soils are formed by the underlying rocks and the diversity of trees. The trees present in forests are heterogeneous in nature.
• Due to this reason, forest soils are heterogeneous in nature.
