2. ABOUT ARUNACHAL PRADESH Popularly known as ‘Land of the Dawn-lit-Mountains’, Arunachal Pradesh is India’s remotest state and the first Indian soil to greet the rising sun.

One of the exciting facts about Arunachal Pradesh is that it is the largest of the seven sister states in Northeast India, spread over 83,743 km. Arunachal has an international border of over 1600km with China in the north, Myanmar in the east, and Bhutan in the west. Arunachal is home to the easternmost village of India, Dong Village, located in Dong Valley of Anjaw district bordering China and Myanmar. You need an inner line permit even if you are an Indian citizen to explore Arunachal Pradesh, which only allows you to spend 15 days.

4. GEOGRAPHY Arunachal Pradesh is land of peanuts in the foothills of the  Himalayas  in  northeast India . It is spread over an area of 83,743 km 2  (32,333 sq mi). 98% of the geographical area is land out of which 80% is forest cover; 2% is water. River systems in the region, including those from the higher Himalayas and  Patkoi  and  Arakan Ranges , eventually drain into the  Brahmaputra River . Elevation ranges from mountains that are above 7,000 metres (23,000 ft), to the towns in the plains with an elevation of less than 300 metres (980 ft). Arunachal shares international borders with  Bhutan ,  Tibet  ( China ) and  Burma (Myanmar) . Internally, Arunachal borders the states of  Assam  and  Nagaland . Arunachal is called the "orchid state of India" and "dawn-lit mountain/Land of Dawn/Land of Dawn-Lit Mountains".

5. climate The weather and the climate of Arunachal Pradesh are quite distinct from the rest of the country. The climate of the state is dominated by the Himalayan system and the altitudinal variations. The climate is highly hot and humid at the lower altitudes and in the valleys covered by swampy dense forest particularly in the eastern section, while it becomes exceedingly cold in higher altitudes. The rainfall of Arunachal Pradesh in amongst the heaviest in the country .

6. MINERALS FOUND IN ARUNACHAL PRADESH State is having variety of minerals like coal, Petroleum and Natural Gas,Dolomite , Limestone,Graphite,Asbestos,Placer gold,Iron,Marble,Ferro-Sillicon Grade, Quartzite, Lead&Zinc,Minor Minerals( Sand,Gravel,Boulders,soil,etc .)

7. COAL Coal is a combustible black or brownish-black  sedimentary rock , formed as  rock strata  called  coal seams . Coal is mostly  carbon  with variable amounts of other  elements , chiefly  hydrogen ,  sulfur ,  oxygen , and  nitrogen .Coal is a type of  fossil fuel , formed when dead  plant matter  decays into  peat  and is converted into coal by the heat and pressure of deep burial over millions of years.Vast deposits of coal originate in former  wetlands  called  coal forests  that covered much of the Earth's tropical land areas during the late  Carboniferous  ( Pennsylvanian ) and  Permian   times.Many significant coal deposits are younger than this and originate from the  Mesozoic  and  Cenozoic  eras .

8. limestone Limestone ( calcium carbonate  CaCO 3 ) is a type of  carbonate   sedimentary rock  which is the main source of the material  lime . It is composed mostly of the  minerals   calcite  and  aragonite , which are different  crystal forms  of  CaCO 3 . Limestone forms when these minerals  precipitate  out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains  fossils  which provide scientists with information on ancient environments and on the  evolution  of life.

9. ASBESTOS Asbestos is a naturally occurring fibrous  silicate mineral . There are six types, all of which are composed of long and thin fibrous  crystals , each fibre being composed of many microscopic "fibrils" that can be released into the atmosphere by  abrasion  and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including  mesothelioma ,  asbestosis , and  lung cancer . As a result of these health effects, asbestos is considered a serious health and safety hazard.
