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.
1 The mantle is made up of semi-molten rock called magma. 2  In the upper parts of the mantle the rock is hard, but lower down the rock is soft and beginning to melt. 3  The crust is the outer layer of the earth.4  It is a thin layer between 0-60 km thick. 5  The crust is the solid rock layer upon which we live. It has a thickness of approximately 2,900 km. 2  The mantle is made up of semi-molten rock called magma. 3  In the upper parts of the mantle the rock is hard, but lower down the rock is soft and beginning to melt. 4  The crust is the outer layer of the earth.
