Explanation:

1. Question 1: A dinosaurologist focuses on dinosaurs, a subset of fossil study, so the statement is true.
2. Question 2: Fossils are preserved remains/traces of ancient organisms; option (a) is the most accurate basic definition.
3. Question 3: Most fossils form when remains are buried in sediments, which later harden into rock.
4. Question 4: Fossils show physical traits of ancient organisms from the past.
5. Question 5: Paleontologists are scientists who study fossils (ancient life).
6. Question 6: Fossils are the primary clues about past organisms.
7. Question 7: Petrification is the process of organic material turning to stone.
8. Question 8: Sedimentary rocks form from layered sediments, which most often trap and preserve fossils.
9. Question 9: The process of bones turning to stone is called petrification.
10. Question 10: A mold fossil forms when an organism decays, leaving an empty imprint in rock.
11. Question 11: Fossils are often eroded out and found in large numbers near beaches.
12. Question 12: Amber forms when tree sap hardens over time.
13. Question 13: The sequence of a tree falling, amber being buried matches image C.
14. Question 14: Finding the finished fossil matches image B.
15. Question 15: Sap hardening into amber matches image D.
16. Question 16: Tree sap trapping an insect matches image A.
17. Question 17: Footprints are a type of trace fossil (image B).
18. Question 18: A full animal imprint is a mold fossil (image C).
19. Question 19: A 3D opposite of a mold is a cast fossil (image D).
20. Question 20: Animals preserved in amber are true form fossils (image A).
