Environment problem created by Extracting  and minning

The environment side effect of extracting and mining projects can be studied in three
categories as under:
  • Effect within and around the area covered by the dam and reservoir.
  • Underground effects caused by emptying of area.
  • Regional effects in terms of overall aspects inclusive of resources use and socio￾economic aspects.
  •  It has also been participating in India Expeditions to Antarctica right from the very first expedition.
GSI with its headquarters at Calcutta functions six regions, three specialised wings and a training institute. Each year GSI takes up about 1100 investigations in geological mapping, mineral assessment, geotechnical and environment studies, air borne geo-physical surveys as well as geological and geophysical surveys in bordering seas. Output of these efforts is in the form of scientific and technical reports, professional papers, maps and inventories and various types of publications such as memoirs, records, bulletins, Indian minerals and
Palentologica Indica.

What are the scope of the environment?

The scope of the environment are it consist four segment Atmosphere Hydrosphere Lithosphere   Biosphere Atmosphere :- Atmosphere act as the blanket to protect from the ultraviolet ray which comes outs from the sun. On the earth it sustain life . The atmosphere is composed of nitrogen and oxygen. There are so many gases like argon ,carbon dioxide and trace gases. Hydrosphere :- Hydrosphere consist of all water bodies resources like ocean, seas ,lakes ,rivers ,glacier ground water etc. Hydrosphere In the earth 97% ,earth water supply is in oceans. About 2% water are in icecapes and glacier. Only 1% fresh water is available  in the water bodies for human consumption.   The water bodies are river ,lake and ground water. Lithosphere:- Lithosphere is the outer part of the earth .It consist of minerals occurring in earth crust and soil. example:- mineral ,organic matter ,air and water. Lithosphere Biosphere:- Biosphere indicate the l...

What is natural resources and it's types?

Image
                Natural resources Natural resources are the resources which comes out from the nature to fulfill the human needs. Natural resources Natural resources is divided into two part  Renewable resources Non-renewable resources 1 . Renewable resources:- renewable resources which can renewed  along with their exploitation is known as renewable resources . Example:- soler energy ,wind energy etc Renewable resources 2. Non-renewable resources:- Non renewable resources are the resources which cannot renewed after exploitation. It take million of years to formed the resources,this type of resources is know as non renewable resources. Example :- fossil fuel etc Non renewable resources 3 cyclic resources:-resources there is no final use as they can be used continuously.  Example:- water. used in industry and domestic ways can be cleaned and used again for similar or other purpose. Such resources...
