Rock Cycle for Kids
As all the students flooded into the classroom and started to unpack, the teacher, Mrs.Bentley, said, "Today you are going on a mini field trip to a park with Mrs.Crystal, who studies rocks and minerals! What you're about to learn is a surprise!" The students cheered, wondering why they were going there. They gladly followed Mrs.Crystal out of the room and to the park nearby.

It flows down, burning everything in its path.

Reaching into her bag, she pulled out 10 round igneous rocks. All students crowded around. She scooped them back up, and said, "That's not the end of it! The igneous rocks gets broken down by erosion and weathering such as wind, rain, and ice, turning them into sediments! These sediments are usually found near water sources. Some of them even have fossils in them due to dead animals that sink to the lake/ocean/sea/river floor, and other sediments pile on top of it and more and more and more.... so the fossil and all the sediments and the occasional fossil are compacted and cemented."
