Question
Assertion (A): Earthquakes accompany volcanic eruptions.
Reason (R): volcanoes spew water vapour and dust particles into the atmosphere.
- Both A and R are true, and R is the correct explanation of A
- Both A and R are true, but R is not the correct explanation of A
- A is true, but R is false
- A is false, but R is true
Hint:
Both A and R are true but R is not the correct explanation of A
The correct answer is: Both A and R are true, but R is not the correct explanation of A
Moving magma and volcanic fluids cause earthquakes. They occur in swarms before and eruption. They are caused by liquid magma, hot fluids and gases forcing their way through the crust to reach the surface.
When a volcano erupts volcanic ash along with water vapour and other hot gases is part of the dark ash column that rises above the volcano.
