How does the location of a volcano affect the magma composition?
What will be an ideal response?
Answer: The location of the magma do affect the composition of the magma since the magma composition mainly depends upon the rocks or the layer that assimilated while its rising to reach the earth surface from the. If the magma come out from a volcano located over the crust it gets enough time to undergo differentiation and assimilation with the rock while rising. While in case of volcano located in the ocean, the crust become thinner and thus magma gets less time to undergo differentiation and assimilation with surroundings rock while rising. Thus the magma are more acidic in continental volcanoes where as basic in case of oceanic volcanoes.
