Fossil
The preserved remains or traces of organisms found in rock layers over time.
What is a fossil?
A sudden drop in fossil diversity often signals this major event.
What is a mass extinction?
Structures with similar functions but different origins are called these.
What are analogous structures?
This motion of Earth causes day and night.
What is rotation?
This is the largest ocean on Earth.
What is the Pacific Ocean?
This fossil forms when minerals fill in a mold, creating a 3‑D copy of the organism.
What is a cast?
This type of evolutionary change happens slowly and steadily over time.
What is gradual evolution?
This type of evolutionary change happens quickly after a major event.
What is sudden change?
This phase occurs when the Moon is completely dark from Earth’s view.
What is a New Moon?
This U.S. state is known as the Sunshine State.
What is Florida?
This fossil type is most likely to show very fine details like skin patterns or leaf veins.
What is carbonization?
The extinction event that wiped out the dinosaurs about 66 million years ago.
What is the K-PG Event?
This type of evidence studies organisms before they are born or hatched.
What is embryology?
This force slows objects down when surfaces rub together.
What is friction?
This instrument has 88 keys.
What is Piano?
A footstep would be considered this type of fossil.
What is a trace fossil?
The study of how fossils appear in rock layers over time provides evidence for this scientific theory.
What is a evolution?
These embryo structures resemble gill slits in early development.
What are pharyngeal pouches?
This force pulls objects toward Earth.
What is gravity?
Suzanne Colins wrote this book.
What is Hunger Games?
A insect suspended in amber would be considered this type of fossil.
What is original material?
Fossils in younger rock layers often show this compared to older fossils.
What is complexity?
Structures with similar origins but different functions are called these.
What are homologous structures?
This law states that an object in motion stays in motion unless acted on by a force.
What is Newton's first law?
This group sang the hit song “Bohemian Rhapsody.”
Who is Queen?
