weathering and erosion causes the rock to break down and
after the sedimentary rock gets broken down from the wreathing plate motion or uplift begins to happen causing the broken up rock to go below the earths mantle
hi i am igneous rock
this is below the earths surface where the sedimentary rocks are and also where the magma is so after a while the magma heats up the sedimentary rocks
know after the Sedimentary rocks are heated with tremendous heat and pressure, it will melt and be back again to magma. After some time it will cool and harden and will become Igneous rocks.
