Briefly explain how magma can originate at spreading zones if temperatures at such shallow depths
cannot alone produce melting What will be an ideal response?
The material is kept from melting because the lithostatic pressure of the overlying rock raises its
melting temperature. The divergence of the plates and the fracturing that accompanies it reduce the
pressure and lower the material's melting temperature, which allows the rock to melt and become
magma.
