7. describe how a footprint of a dinosaur may have been preserved to form a
Answer
Brief Explanations:
When a dinosaur walked on soft sediment like mud or sand, it left an impression. Over time, more sediment was deposited on top of the footprint. The lower - layer sediment with the footprint was compacted and cemented together by minerals in the water, turning into rock. Eventually, through processes like erosion, the overlying rock layers were removed, revealing the fossilized dinosaur footprint.
Answer:
When a dinosaur stepped on soft sediment, it made an impression. Subsequent sediment deposition covered the footprint. Compaction and cementation turned the sediment into rock. Erosion later exposed the fossilized footprint.
