• Dachigam National Park is located 22 kilometers from Srinagar, Jammu and Kashmir. It covers an area of 500 km². The name of the park literally stands for "ten villages" which could be in memory of the ten villages that were relocated for its formation
• Khangchendzonga National Park also Kanchenjunga Biosphere Reserve is a National Park and a Biosphere reserve located in Sikkim, India
• The Nanda Devi National Park or Nanda Devi Biosphere Reserve, established in 1982, is situated around the peak of Nanda Devi in the state of Uttarakhand in Northern India
• The Sundarbans is a mangrove area in the delta formed by the confluence of Ganges, Brahmaputra and Meghna Rivers in the Bay of Bengal.

• The air near the surface consists of nitrogen- 78% and oxygen- 20.9%.
• Thus option A is correct.
• Carbon Dioxide is found in very low quantities i.e. 0.003% hence incorrect.

• The highest active volcano in the world is Ojos del Salado on the Chile-Argentina border in the Central Andes. It rises to 6887 m / 22,595 ft. It has not erupted in historic times, but is an active volcano.
  

• Equatorial radius of the earth = 6378 km
• Polar radius of the earth = 6356 km
• Thus the nearest option is 6371 km . B is the correct option.

• The earth is not a complete sphere as it is a little flat at poles and bulges at the equator which makes its equatorial diameter greater than its polar diameter.
• The equatorial diameter of the Earth is 40075 km.

• The principle factor deciding the temperature of any place on Earth is the angle of sun rays falling upon the surface of the earth. Vertical rays i.e. rays inclined towards the surface bring in more insolation thus earth gets warmer. On the other hand, when the sun rays are inclined away from the earth's surface i.e. slanting rays,  brings in less insolation and thus temperature remains cooler. Thus B is correct.
• Option A is wrong as the distance from the sun does not contribute significantly towards the variation in temperature on earth.
• Option C is wrong as evaporation occurs in all the seasons.
• Option D is wrongly stated.

• New York City is situated in the banks of river The Hudson.
  
• The Hudson River is a 315-mile (507 km) river that flows from north to south primarily through eastern New York in the United States.
  
• The river originates in the Adirondack Mountains of Upstate New York, flows through the Hudson Valley, and eventually drains into the Atlantic Ocean, between New York City and jersey city.
  
• The river enters the Hudson Valley, flowing along the west bank of Albany and the east bank of Rensselaer.
  

• The water hemisphere has only one-eighth of the world's land, Australia, New Zealand, Antarctica, a small part of Southeast Asia and the southern part of South America are in the water hemisphere.
•  Most of the Pacific Ocean and the Indian Ocean is on the water hemisphere.
• Southern Hemisphere climates tend to be slightly milder than those at similar latitudes in the Northern Hemisphere, except in the Antarctic which is colder than the Arctic.
• This is because the Southern Hemisphere has significantly more ocean and much less land; water heats up and cools down more slowly than land.

The biosphere is the layer of the planet Earth where life exists. This layer ranges from heights of up to ten kilometres above sea level. It is the fourth component of the earth. Biosphere is a life-supporting global ecosystem, where each living things depends on each other and the environment. The biosphere extends over the Earth's surface in a thin layer from a few kilometers into the atmosphere, in very cold environments, to the deep-sea vents of the ocean depths, in very hot environments.
