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...

What is Engineering? | Types of Engineering

  What is Engineering? | Types of Engineering           Engineers use science and math to come up with practical solutions to problems.   (Image credit: Ollyy | Shutterstock ) Engineering is the application of science and math to solve proble null ms. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. In his book, " Disturbing the Universe " (Sloan Foundation, 1981), physicist Freeman Dyson wrote, "A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering." The history of engineering is part and parcel of the history of human civilization. The   Pyramids   of Giza,   Stonehenge , the ...
