 ENERGY RESOURCES 


In physics, energy is AN indirectly discovered amount that's usually understood because the ability of a physical system to try and do work on alternative physical systems Since work is outlined as a force acting through a distance (a length in space), energy is usually like the power to exert pulls or pushes against the fundamental forces of nature, on a path of a particular length. In straightforward language, energy will be outlined because the capability to try and do the work.

 • Energy Resources: In Environmental Studies A natural resources that may be regenerate by humans into varieties of energy go order to try and do helpful work! Non-renewable Resources of Energy: These area unit energy resources that can't get replaced once the are used or want thousands to countless years to get replaced. Fossil fuels area unit energy resources that fashioned from the buried remains of plants and animals that lived countless yea past. The plants keep energy from the sun throughout chemical change. Animals keep this same

• Renewable Resources of Energy one AN energy resource that may be used and replaced i short amount of your time. Renewable energy is energy that comes from natural daylight, wind, rain, tides, and geothermic heat, that area unit renewable (naturally Sixteen Personality Factor Questionnaire of world final energy consumption comes from renewable, with 100 percent returning from m Climate offered biomass, that is primarily used for heating, and 3.4% from electricity. The share of renewable in electricity generation is around nineteeninternational electricity returning from electricity and three from new renewable. :

Importance of renewable sources of energy:

Accessibility: Coal, fossil fuel and oil reserves area unit finite and hidden. AN unknown and quantity of every resource is buried deep below  or under the ocean. As a lot of is thus finding new sources becomes harder and costlier, and exploiting them as a result of difficult and generally dangerous likewise, Marginal reserves, like ol sands, re burning of giant amounts of fossil fuel to refine them into usable oil. Drilling below the oc will cause ruinous accidents, like Brits rock oil oil spill of 2010. Renewable in contrast, is as simple to seek out as wind or daylight. y bound food .

Stability and Safety: The daily worth of oil depends on several factors, as well as te stability in traditionally volatile regions. Political strife has caused energy crises, as well as th occurred in 1973 and 1979. Renewable energy will be domestically made and thus isn't vu to distant political upheavals. several of the protection considerations encompassing fossil fuels, ya explosions on oil platforms and collapsing coal mines, don't exist with renewable energy.


Pollution: Renewable energy is much cleaner than fossil fuels. Coal mining and rock oil expire and refinement produces solid cyanogenic wastes, like mercury and alternative serious metals. The coal to supply electricity uses massive quantities of water usually discharges arsenic and lead surface waters and releases greenhouse emissionsulphur dioxidechemical element oxides and mercury into f petrol and other rock oil merchandise cause similar pollution. 

These pollutants cause respin com sicknesses and death in humans, manufacture air pollution that damages buildings and destroys Fe ecosystems, and use up the ozonosphere.

Land Resources


Land resource means that the land that's offered for exploitation, like non agricultural land buildings and developing townships, land for agriculture, land for industrial and commercial etc. natural resource talk to the resources that area unit offered from the land, therefore the agriculture that contain natural plant food for growth of the merchandise sown; the underground water varied minerals like coal, bauxite, gold and alternative raw materials area unit the natural resource

natural resource constitutes the surface of earth that's not coated by water. Sol or land rese occupies a central position in any system because it sustains the expansion of plants that supports the expansion of all alternative life forms. natural resource area unit thought-about as non renewable nat resource. In Asian nation natural resource area unit segmental into totally different classesforty third surface area is pl

Climate plays a vital role in soil formation, Asian nation has regarding six major kinds of soil like sediment soils, black solls, red soils, mountain soils, desert soils and autoimmune disease soils (latosols). It implies the aim that the land is employed and the way the biophysical characters of land are changed for that purpose. 

The pattern of land use in Asian nation are- forests, non agricultural land, barren and a arable land, arable waste land, miscellaneous tree crops and groves, land, tilled land and permanent pastures and alternative pasture. Land use involves the management and modification of natural surroundings or geographical region into engineered surroundings like settlements and semi-natural habitats like cultivatable fields, pastures, and managed woods. It additionally has been outlined as "the total of arrangements, activities, and inputs that individuals undertakes during a bound land cowl kind.

 Land Use practices vary significantly across the planet. The international organization Food and Agriculture Organization water project Division explains that" Land use considerations the merchandise and / or edges obtained from use of the land likewise because the land management actions (activities) meted out by humans to supply those merchandise and edges

"As of the first Nineteen Ninetiesregarding thirteen of the planet was thought-about cultivatable Land, with twenty sixth in pasture, thirty second forests and solid ground, and 1.5% urban areas. Land use could be a key term within the language of urban planninga trial to avoid land-use conflicts Land use plans area unit enforced through land division and sectionalization laws Land use is once a district is employed for a particular purpose These functions meet the requirements and wishes of individuals. land could also be used because it naturally exists, like employing a lake for swimming and yachting. Or the land could also be modified so it will be used for an additional specific purpose, like a hole being blasted into the facet of a mountain thus railroad will be arranged for trains to have ordinances and laws, such as 

Types of Land Use



There area unit 5 main kinds of land use:

residential, agricultural, recreational, transportation, and commercial: 

Residential: What variety of home does one live in? whether or not you reside in AN flat, town-home, house, or alternative variety of home, the land wherever you reside is employed for residential functionsthis implies the land is employed to produce housing for folks to measure in.
  
Agricultural: If you have ever visited a farm, you have witnessed agricultural land use. Land used for agriculture primarily produces food for folks to eat. this might be growing fruit or vegetables or raising placental mammal that produces meat, eggs, and poultry.

Recreationaldoes one wish to go swimming at the pool or hike at the park? If you are doingyou have got positively taken advantage of recreational land use. this implies that the land is being employed to produce an area for folks to relax and play. several of the lands used for recreation embrace natural options of the land that area unit already there, as well as hiking on mountains, swimming in lakes, and rising saan

 • Transportation: Driving during a automotive, riding on a train, or taking a ride on the subway area unit all nice ways that to expertise land being employed for transportation. once folks build highways, roads, railroad lines, and subways, they're exploitation the land for transportation functions.
Commercial: an ad space is land supposed to be used by for-profit businesses, like workplace complexes, looking malls, service stations and restaurants. it should be purchased outright by a developer for future comes or hired through a true estate broker. this sort of property falls
