Question

a) Differentiate between physical, chemical, and biological weathering b) Explain the different horizons of the soil. of water? How will you calculat​

Answer 1

Answer:

a) The differences between physical, chemical and biological weathering are that physical weathering is done by water, temperature, and wind whereas biological weathering is done by biological organisms and chemical weathering is done by hydrolysis, reduction, and oxidation.

b) The layers of soil are called soil horizons. The the arrangement of these verizon's is known as soil profile.

• Soil horizons different properties of colour and texture of the soil as well as structure and thickness of the horizon.

• The horizon unnamed using the letters O, A, E, B and C.

Answer 2

Physical weathering is the process of weathering Leith physical element like wind ,water etc

Chemical weathering is the weathering with any types of chemical reacting with the rocks

Biological weathering is the weathering by biological organisms through various ways.

The differences between physical, chemical and biological weathering are that physical weathering is done by water, temperature, and wind whereas biological weathering is done by biological organisms and chemical weathering is done by hydrolysis, reduction, and oxidation.

Explanation:  

Weathering is defined as the process that leads to weakening and erosion and breaking down of minerals present on the earth.

This breakdown process can be conducted through physical weathering, through chemical as well as biological.

In biological weathering, degradation and decomposition occur due to the actions of living organisms like bacteria and fungus.

Chemical weathering occurs when processes of oxidation and others can take place.

Physical weathering occurs when rain, sun and wind breakdown the minerals.
