Q1. With reference to methane hydrates in India, consider the following statements: 1. Methane hydrate deposits in the Krishna-Godavari basin have been reported as biogenic in origin. 2. Methane hydrate is formed when water and methane meet at low pressure and high temperature in oceans. 3. The methane hydrate deposit in the Krishna-Godavari basin has been described as a rich source of methane, a natural gas. 4. A cited study found maximum methanogenic diversity in the Krishna-Godavari basin compared with the Andaman and Mahanadi basins. Which of the statements given above are correct?
Explanation
Statements 1, 3 and 4 are correct. PIB reports biogenic methane hydrate deposits in the KG basin, describes the basin's deposit as a rich methane source, and notes maximum methanogenic diversity there. Statement 2 is false because methane hydrate forms at high pressures and low temperatures, not low pressure and high temperature.
