Why do we usually find fossils embedded in solid rock?

Answer: Organisms buried and mineralized

Organisms buried and mineralized ✓ — Correct! Fossilization occurs when organisms are rapidly buried by sediment (mud, sand) after death, protecting them from decay. Over millions of years, sediment layers compress into sedimentary rock. Meanwhile, minerals gradually replace the organic material, creating a rock copy of the organism. Only a tiny fraction of organisms become fossils - it requires specific conditions! Fossils provide evidence of ancient life.

Earthquakes trap animals — Wrong. While sudden burial helps fossilization (volcanic ash, mudslides), earthquakes don't trap animals to create fossils. Fossils form when organisms are buried in sediment that later becomes rock, and minerals gradually replace the organic material over millions of years. It's a slow geological process.

Rocks grow around bones — Wrong. Rocks don't grow around bones. Fossils form through a process where organisms are buried by sediment, which then turns into sedimentary rock over millions of years through compression. The organic material is replaced by minerals, creating a fossil within the rock.
