Magma develops within the mantle or crust when the temperature-pressure conditions favor the molten state. Magma rises toward the Earth's surface when it is less dense than the surrounding rock and when a structural zone allows movement.
Letâs review: Under normal conditions, mantle rock like peridotite shouldnât melt in the Earthâs upper mantle â it is just too cool. However, by adding water you can lower the melting point of the rock. Alternatively, by decompressing the rock, you can bring it to a pressure where the melting point is lower.etâs review: Under normal conditions, mantle rock like peridotite shouldnât melt in the Earthâs upper mantle â it is just too cool.
