Question

Consider the following related to Natural gas hydrates,
1.Natural gas hydrates are a naturally occurring, ice-like combination of natural gas and water found in oceans and polar regions.
2. Natural gas hydrates are considered as vast resources of natural gas and are known to occur in marine sediments on continental shelf margins.
3.Samudra Ratnakar - Indian Oceanographic Research Vessel has the capability to explore and identify the favorable zone of accumulation of Gas Hydrates, which are known to be the future source of hydro-carbon energy.

Which of the statements given above are correct?

• A. a)1 and 2 only
  
• B. b)1 and 3 only
  
• C. c)2 and 3 only
  
• D. d)1,2 and 3
  

Answer 1

The correct option is D d)1,2 and 3


Answer:d

Natural gas hydrates are ice-like structures in which gas, most often methane, is trapped inside of water molecules. Unlike the ice we’re all familiar with that’s derived entirely from water, gas hydrates are in fact highly flammable, a property that makes these crystalline structures both an attractive future energy source as well as a potential hazard.

Hydrates are a much more abundant source of natural gas than conventional deposits. According to the U.S. Geological Survey, global stocks of gas hydrates range account for at least 10 times the supply of conventional natural gas deposits, with between 100,000 and 300,000,000 trillion cubic feet of gas yet to be discovered. India’s Oil Ministry and the US Geological Survey made the discovery of large, highly enriched accumulations of natural gas hydrate — an icy form of the fuel — in the Bay of Bengal.
