What effect does an increase in pressure have on the temperature at which rock melts?
A) We do not know yet.Temperatures needed to melt rock have not yet been achieved in the laboratory.
B) It increases the melting temperature.
C) It lowers the melting temperature.
D) It has no effect on the melting temperature because the melting temperature is independent of pressure.

Question

Quizplus · Accepted Answer

An increase in pressure will increase the melting temperature of rock. This is due to the fact that higher pressure means higher energy is needed to overcome intermolecular forces and break down the crystalline structure of the rock.
