Answer

1. Catastrophic burial prevents decay, allowing fossilization. ### 2. Quick deposition is indicated by many fossils in one layer. ### 3. A polystrate fossil spans multiple sedimentary layers. Explanation 1. Explain Fossil Formation Fossils form when organisms are rapidly buried by sediment, preventing decay and scavenging. This rapid burial often results from catastrophic events like floods or volcanic eruptions. 2. Explain Mass Sedimentary Graves Mass sedimentary graves contain numerous fossils in a single layer, indicating quick deposition of sediments. Such rapid accumulation is typically due to sudden, large-scale events like landslides or tsunamis. 3. Define Polystrate Fossil A polystrate fossil is a single fossil that extends through multiple layers of sedimentary rock, suggesting rapid sedimentation over a short period rather than slow accumulation.
