... 4. Magma is found at mid-ocean ridges because a) The mantle under ridges is more silica-rich than other parts of the mantle, so melts at temperatures at which other parts of the mantle are still solid. b) Convection cells and mantle plumes bring magma up from molten regions near the core-mantle bou ...
