Principle of Superposition:
1. What is the law of superposition? THE LAW OF SUPERPOSTION STATES
THAT THE YOUNGEST LAYER IS ON TOP AND THE OLDEST LAYER IS AT THE
BOTTOM.
2. What is the order of the rock layers from oldest to youngest? A, D, E, B,
C
3. Give 5 facts about an index fossil. MUST BE EXTINCT, ONLY LIVES FOR A
SHORT PERIOD OF TIME, TELLS THE RELATIVE AGE OF ROCKS, UNIQUE,
AND WIDESPREAD
4. What type of rock is shown below? SEDIMENTARY
5. Name the 2 intrusions. C AND E
6. Draw a fault that is older than A,D, and E but younger than B and C.
Fossil Types Vocabulary:
1. ___MOLD__________ are cavities in the shape of an organism,
such as a shell.
2. __INDEX FOSSILS__________ are fossils of organisms that lived a
short time and were abundant.
3. ___PETRIFIED________are formed when minerals replace the hard
parts of an organism and turn into rock.
4. ___CAST___________are copies of an organism’s shape and it fills
in the mold.
5. __PRESERVED________are formed when an organism is trapped in
ROCK, ice, tar, or sap (amber).
6. ___CARBONIZED____ are when plant materials are trapped
between rock and the carbon forms an imprint.
7. ___TRACE___are fossilized footprints, burrows, trails, or nests
of an organism.
