Quizplus · Accepted Answer

Sedimentary rocks are formed from the accumulation of sedimentary particles and organic matter over a long period of time. Fossils of plants and animals are often preserved in sedimentary rocks, making them the best rocks for studying the history of life on Earth. Igneous rocks are formed from the cooling of magma or lava, and metamorphic rocks are formed from the transformation of pre-existing rocks under heat and pressure. While these types of rocks can provide information about Earth's geological history, they do not contain the same level of detail about the evolution of life.
