  Why? What will be an ideal response?

Question 2

Why can an intruding mafic magma assimilate felsic country rock, but an intruding felsic magma

Answer to Question 1

More mafic-felsic rocks melt at lower temperatures than do mafic rocks.

Answer to Question 2

Mafic magma has a higher temperature than felsic magma, while felsic rock melts at lower
temperatures than mafic rock
