Question 7

Which of the following is true of the magma formed from subducted ocean floor material that is eventually incorporated into continental crust?

Accepted Answer

A) the composition of the magma changes from a high silica content to a lower silica content by the incorporation of sediments and other materials when it melts.

C) batholiths may create magma as they move downward into the subduction zone. 
D) it has a low viscosity and rises easily to spread over the surface of the continental crust. 
E) because this magma is exactly like the magma at sea-floor spreading centres,it creates new oceanic crust at the surface.
