Consider the following statements.
1. At present, there are no active volcanoes in India.
2. The main cause of volcanic eruption is associated with plate tectonics, orogeny and sea-floor spreading processes.
Which of the above statements is/are CORRECT?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 2 only.
Statement 1 is incorrect because India hosts an active volcano, Barren Island, located in the Andaman and Nicobar Islands, which last erupted in 2017. Statement 2 is correct because volcanic eruptions are primarily driven by geological processes like plate tectonics (subduction zones), orogeny (mountain building), and sea-floor spreading (divergent boundaries), where magma rises to the surface due to pressure changes in the Earth's mantle.
