Resources and Development class 10 Geography Notes

Resources Everything in our environment which can be used to satisfy our needs and is technologically accessible, economically feasible and culturally acceptable is termed as ‘Resource’. Human beings themselves are essential components of resources. They transform material available in the environment into resources and use them. Classification of Resources Resources can be classified in the following ways: (a) On the basis of origin – biotic and abiotic (b) On the basis of exhaustibility – renewable and non-renewable (c) On the basis of ownership – individual, community, national and international (d) On the basis of the status of development – potential, developed stock and reserves a) On the Basis of Origin – Biotic and Abiotic Biotic Resources are obtained from the biosphere and have life. Eg: Human beings, flora and fauna, fisheries, livestock etc. Abiotic Resources: All those things which are composed of non-living things are called abiotic resources. Eg: rocks and me...

The Journey of Saint Mother Teresa

The Journey of a Saint “Life is not worth living unless it is lived for others.”- Mother Teresa. A name that resonates with charity and humility, she taught us the true meaning of selfless living. A life so dedicated to the cause of providing for others, that it has come to be identified with the stories of the million lives she touched with her healing hand. Decorated with the highest of awards and recognitions worldwide, our humble lady had but one thing to say, “I personally am most unworthy, and I having avowed poverty to be able to understand the poor, I choose the poverty of our people. But I am grateful and I am very happy to receive it in the name of the hungry, of the naked, of the homeless, of the crippled, of the blind, of the leprous, of all those people who feel unwanted, unloved, uncared, thrown away of the society, people who have become a burden to the society, and are ashamed by everybody.” (10 December, 1979, Nobel Prize Speech) While her deeds of sel...

🛑Structure of the Atom🛑

🛑Structure of the Atom🛑 ➖By 1900, it was discovered that the atom was not a simple, indivisible particle, but rather it contains sub-atomic particles. ➖J.J. Thomson discovered the sub-atomic particle namely ‘electron.’ ➖J.J. Thomson was the first person who proposed a model for the structure of an atom. ➖In 1886, E. Goldstein discovered the presence of new radiations in a gas discharge and named them canal rays. ➖Another positively charged sub-atomic particle was discovered with experiments of canal rays and named it proton. 🧿Thomson’s Model of Atom ➖Thomson proposed that an atom consists of a positively charged sphere and the electrons (negative charge) are embedded in it (as shown in the image given below). ➖Further, Thomson said that the negative and positive charges are equal in magnitude. Thus, the atom as a whole is electrically neutral. 🧿Rutherford’s Model of Atom ➖E. Rutherford is popular as the ‘Father’ of nuclear physics. ➖Rutherford is largely known for his work on radio...
