Dr. Kayleigh studies rock formations all over the world. She is working on a study of two rock formations. The information from the study is as follows: Rock A formed from liquid rock. Rock B formed from small pieces of rock in a different place. Rocks A and B formed at about the same time. QUESTION Are Rocks A and B the same types or different types of rock and why? The rocks are...

The rocks are different types of rock! Rock A is classified as an igneous rock because it formed from the cooling and solidification of liquid rock, known as magma or lava. On the other hand, Rock B is a sedimentary rock since it originated from smaller pieces of rock that accumulated and cemented together, usually in a different location than where it was formed. Their distinct formation processes highlight the fascinating diversity in the world of geology! If you think about it, each rock tells a unique story of its environment and the geologic processes involved. Just imagine Rock A bubbling away in a molten state beneath the Earth’s surface, while Rock B patiently gathers materials over time, layering in a serene setting. The differences between these rocks can offer important clues about Earth's history and the conditions under which they formed.
