What effect, if any, does the pressure to which a material is subjected have on the melting temperature of the material?
A) There is no effect of pressure on melting temperature.
B) Within Earth's interior the pressure is decreased (compared to the surface), causing the melting temperature to increase (compared to the surface).
C) Within Earth's interior the pressure is increased (compared to the surface), causing the melting temperature to decrease (compared to the surface).
D) Within Earth's interior the pressure is increased (compared to the surface), causing the melting temperature to increase (compared to the surface).

Pressure increases with depth in the Earth's interior, which generally raises the melting temperature of materials. This is because higher pressure tends to stabilize the solid phase, requiring more heat to induce melting.
