Astronomers studying the planet of Acer have detected igneous rock under its surface. One astronomer makes a claim that some of
the material that this igneous rock formed from used to be in sedimentary rock on the surface of Acer. If the scientist is correct, how could the sedimentary rock have become igneous rock?
Sedimentary rocks becomeigneous rocks when sedimentary rocks are exposed to heat and pressure. Then they melt into magma and then the magma cools off and solifides to a igneous rock
