Igneous rocks can be formed from magma that solidifies deep beneath the earth's surface. when it cools quickly, it creates more smooth and shiny rock with fine grains

sedimentary rocks are made from the weathering and erosion of pre-existing rocks. if the sediment is buried deeply, it becomes compacted and cemented. sedimentary rocks also form from organic material and often contain fossils.

metamorphic rock is a result of transformation of pre-existing rock subjected to high heat and pressure. this causes the minerals in the rock to become unstable so they either reorient themselves into layers, giving them a striped look or recrystallize into larger crystals.

based on the reading, how would you classify this rock?

a. sedimentary rock because of its layers.

b. metamorphic rock because of its stripes.

c. igneous rock because of its large crystals
