Question
What are the causes of Volcanic Activity?
✓

Answer

  • The temperature increases at the rate of 10°C for every 35 meters with pressure.
  • So the interior of the earth is in a semi-molten state called magma.
  • The magma under great pressure dissolves great volume and combustible gases.
  • This makes volcanic material burst forth through the weak spots in the earth’s crust.
