Natural Resources

  1. 1. NATURAL RESOURCES Presented by: Jenny Raut(P.D.I.M.T.R) & Preeti Mahurkar(P.D.I.M.T.R)
  2. 2. What are resources? <ul><li>Any material which is part of earth and satisfy human need and add value is called as resource. </li></ul><ul><li>Example:rocks,minerals,soil,,rivers, </li></ul><ul><li>plants & animal. </li></ul><ul><li>Human is a resource because developing his skill, he can develop other resource by adding value to the physical material . </li></ul>
  3. 3. Value are of 4 kind: <ul><li>Economic value - production </li></ul><ul><li>Legal value -clean air,water(quality) </li></ul><ul><li>Aesthetic value - beauty of </li></ul><ul><li>nature(forest,mountain,lake) </li></ul><ul><li>Ethical value -responsibility to preserve(natural parks for future) </li></ul>
  4. 4. Types Of Resources <ul><li>Natural Resources </li></ul><ul><li>Human Resources </li></ul><ul><li>Man-made Resources </li></ul>
  5. 5. Natural Resource <ul><li>It is the form of matter/energy which is available in the earth and get used by living thing. </li></ul><ul><li>Eg:air,water,soil,minerals,fossil-fuel,wildlife. </li></ul>
  6. 6. Category Of Natural Resource <ul><li>Renewable </li></ul><ul><li> </li></ul><ul><li>non-Renewable </li></ul>
  7. 7. Renewable Resource <ul><li>These are those resources which are renewed/replenished fastly and are not affected by human activity. </li></ul><ul><li>Renewable energy sources are more commonly used by developed nations. </li></ul><ul><li>Example:solar energy, </li></ul><ul><li>water </li></ul><ul><li>air </li></ul><ul><li>biomass </li></ul><ul><li>wood </li></ul>
  8. 8. solar energy
  9. 9. Hybrid Of Wind And Solar energy
  10. 10. Biomass Energy
  11. 11. Non-Renewable <ul><li>These are those resources which are not renewed/replenished and are affected by human activity. </li></ul><ul><li>Over 85% of the energy used in the world is from non-renewable supplies </li></ul><ul><li>Most developed nations are dependent on non-renewable energy sources such as fossil fuels (coal and oil) and nuclear power. </li></ul><ul><li>Industrialized societies depend on non-renewable energy sources. </li></ul>
  12. 12. Example Of Non-Renewable Resource <ul><li>COAL </li></ul><ul><li>OIL </li></ul><ul><li>NATURAL GAS </li></ul><ul><li>OIL SHALE AND TAR SANDS </li></ul><ul><li>NUCLEAR POWER </li></ul>
  13. 13. Coal & Energy Security
  14. 14. COAL <ul><li>Coal is the most abundant fossil fuel in the world with an estimated reserve of one trillion metric tons. </li></ul><ul><li>world's coal reserves exist in Eastern Europe and Asia considerable in United States . </li></ul><ul><li>Coal formed slowly over millions of years from the buried remains of ancient swamp plants </li></ul>
  15. 15. Formation Of Coal
  16. 16. Types of coal <ul><li>Coal are formed due to differences in the pressure and temperature during formation . </li></ul><ul><li>Lignite coal . </li></ul><ul><li>about 50% carbon , highest water 50%,low amounts of smog-causing sulfur. </li></ul><ul><li>Bituminous coal </li></ul><ul><li>about 85% carbon and 3% water </li></ul><ul><li>Anthracite coal </li></ul><ul><li>almost 100% carbon ,hardest form of coal. </li></ul>
  17. 17. Use Of Coal <ul><li>Coal is used to produce 50% of the electricity in the United States. </li></ul><ul><li>used for heating and cooking in less developed countries while rural areas of developed countries. </li></ul>
  18. 18. OIL <ul><li>Crude oil or liquid petroleum, is a fossil fuel that is refined into many different energy products </li></ul><ul><li>e.g., gasoline, diesel fuel, jet fuel, heating oil </li></ul>
  19. 19. Formation Of Oil <ul><li>Oil forms underground in rock such as shale , which is rich in organic materials. Wells are drilled into these oil reservoirs to remove the gas and oil. </li></ul><ul><li>About 25 percent of the oil recovers during primary stage </li></ul><ul><li>During secondary stage hot water is injected into the reservoir around the well </li></ul><ul><li>This water forces the remaining oil toward the area of the well from which it can be recovered </li></ul>
  20. 20. <ul><li>Tertiary method is used to recover as much oil as possible. This involves pumping steam, carbon dioxide gas or nitrogen gas into the reservoir to force the remaining oil toward the well. </li></ul>
  21. 21. Availability Of Oil <ul><li>50 percent of the world's oil is found in the Middle East </li></ul><ul><li>Additional reserves occur in North America </li></ul>
  22. 22. NATURAL GAS <ul><li>Natural gas is a mixture of gases methane ethane propane butane . </li></ul><ul><li>It is cleanest burning fossil fuel </li></ul><ul><li>propane and butane are removed from the natural gas and made into liquefied petroleum gas ( LPG ) </li></ul><ul><li>Natural gas is highly flammable and is odorless </li></ul><ul><li>natural gas is used primarily for heating, cooking, and powering vehicles </li></ul>methane
  23. 23. <ul><li>Most of the world's natural gas reserves are found in Eastern Europe and the Middle East </li></ul><ul><li>Supply will last an estimated 100 years. </li></ul>
  24. 24. OIL SHALE AND TAR SANDS <ul><li>Oil shale and tar sands are the least utilized fossil fuel sources. Oil shale is sedimentary rock with very fine pores that contain kerogen , a carbon-based, waxy substance. </li></ul><ul><li>If shale is heated to 490º C, the kerogen vaporizes and can then be condensed as shale oil, a thick viscous liquid </li></ul><ul><li>Tar sand is a type of sedimentary rock that is impregnated with a very thick crude oil </li></ul>
