Grade 4 Reading Comprehension Quiz - The Ancient Fossil - Supported Learning Quiz

The Ancient Fossil During a school field trip to a natural history museum, students examined fossils that were millions of years old. One fossil showed the imprint of a fish that once lived in an ancient ocean. The museum guide explained that fossils form when plants or animals become buried in layers of sediment. Over time, the materials around them harden into rock. Scientists study fossils to learn about life on Earth long before humans existed. Looking at the fossil, students imagined what the ancient ocean might have looked like millions of years ago. The visit helped them understand how fossils provide clues about Earth’s history.
