C)differentiation
D)partial melting

Question

Quizplus · Accepted Answer

Assimilation is the process in which magma incorporates surrounding host rock, which changes the composition of the magma. Magma mixing involves the mixing of two or more magmas, while differentiation is the process by which a single magma type separates into different minerals as it cools. Partial melting is the process by which rocks partially melt to form magma. Hence, the best choice is A) assimilation.
