select the correct answer.\na 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 earths surface. why did the rock not become an igneous rock?\na. it lay in a region that was close to the salt - filled ocean.\nb. it contained organic material from a number of insects.\nc. it did not experience high enough pressure for compaction.\nd. it had not experienced high enough temperatures to melt.\ne. it had a composition that was not homogenous.

Answer

Brief Explanations:

Igneous rocks form from the cooling and solidification of molten rock (magma or lava). For a rock to become igneous, it must first melt. In this case, the sedimentary rock turned into a metamorphic rock instead of igneous because it didn't reach high - enough temperatures to melt.

Answer:

D. It had not experienced high enough temperatures to melt.
