false
question 28
2 pts
oceanic and continental lithosphere differ in which of the following ways?
thickness
density
composition
none of the options are correct
all options are correct

Explanation:

For Question 27: During metamorphism, minerals recrystallize but do not melt (melting would lead to igneous rock - formation). They can align in a preferred orientation under stress.
For Question 28: Oceanic lithosphere is thinner, denser and has a different composition (basaltic) compared to continental lithosphere (granitic which is thicker and less - dense).

Answer:

Question 27: B. False
Question 28: E. All options are correct
