50. igneous, sedimentary, and metamorphic rocks are found at the same cliff side. which statement is correct about the rocks at this location? m. all three types of rock will become metamorphic if they stay at the surface of earth. p. if this location is buried deep underground, only the metamorphic rock will melt because it has already been heated before. r. the metamorphic rock and sedimentary rock were already at this location and magma flowed into the other rocks. s. the igneous rock will become metamorphic rock after the rock in the cliff side turns into sediment.
Answer
Brief Explanations:
Metamorphic and sedimentary rocks are already present, and the intrusion of magma forms igneous rock. Magma flowing into pre - existing rocks is a common way igneous rock is formed in such a setting. Option M is incorrect because rocks at the Earth's surface don't become metamorphic just by staying there. Option P is wrong as all rock types can melt under high enough temperature and pressure deep underground, not just metamorphic rock. Option S has an incorrect sequence of rock - type changes.
Answer:
R. The metamorphic rock and sedimentary rock were already at this location and magma flowed into the other rocks.
