Weathering 






what is weathering 


Weathering describes the breaking down or dissolving of rocks and minerals on the surface of Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.


Types of weathering 

1. Physical Weathering

2. Chemical Weathering 

3. Biological Weathering 


Physical Weathering 

Also known as mechanical weathering, physical weathering involves the breakdown of rocks and minerals into smaller pieces without changing their chemical composition. Various environmental factors drive this process, including temperature fluctuations, pressure changes, and biological activity.


Chemical Weathering 

Chemical weathering is a process in which rocks and other materials are broken down by chemical reactions12. It occurs when water and chemicals dissolved within it come into contact with rocks and change their composition12. Some of the chemical weathering processes are dissolution, solution, carbonation, hydration, oxidation, and reduction2.



Biological Weathering 


Biological weathering also means organic weathering. It is the disintegration of rocks as a result of the action by living organisms. Plant and animals have a significant effect on the rocks as they penetrate or burrow into the soil respectively. Biological weathering can work hand in hand with physical weathering by weakening rock or exposing it to the forces of physical

  Nitrogen Cycle Nitrogen Cycle is a  biogeochemical process  through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. It involves several processes such as nitrogen fixation, nitrification, denitrification, decay and putrefaction. Nitrification In this process, the ammonia is converted into nitrate by the presence of bacteria in the soil. Nitrites are formed by the oxidation of ammonia with the help of  Nitrosomonas  bacteria species. Later, the produced nitrites are converted into nitrates by  Nitrobacter . This conversion is very important as ammonia gas is toxic for plants. The reaction involved in the process of Nitrification is as follows: 2NH 3  + 3O 2  → 2NO 2 –  + 2H +  + 2H 2 O 2NO 2 –  + O 2  → 2NO 3 – Assimilation Primary producers – plants take in the nitrogen compounds from the soil with the help of their roo...

 counselling in education What is Educational Counselling? Educational Counselling mainly refers to providing assistance and guidance to students in making the right choices in their studies, be it their educational plans, career aspirations, choice of stream and specialization as well as the selection of college or university as per their interests and preferences. What is an Educational Counsellor? An Educational Counsellor mainly works with school and college students in academic environments. Many schools have their own educational counsellors to help students find the right career and make informed choices in their studies especially special needs children and educational counsellors also assist students in dealing with the personal issues impacting their academic journey. To resolve such issues, and Educational Counsellor also interacts with the student’s parents or guardian or teachers to help them in figuring out the best solutions for the student’s problems.
