Select the correct answer.
A 20-pound sedimentary rock formed on a mountain cliff near the sea. The rock was made up of grains of sand, pebbles, and exoskeletons of tiny
insects. It was held together by calcite. One day, the rock fell into the ocean and over time was buried deep inside Earth. Once inside, the rock was
no longer sedimentary but instead turned into a metamorphic rock. After many years, it returned to Earth's surface. Why did the rock not become an
igneous rock?
