This is a hollow area in sediment in the shape of an organism
3
Mold A 100
4
This provides evidence of the activities of ancient organisms
5
Trace Fossils A 200
6
This type of fossil is created when minerals replace all or part of an organism

10
Scientist that studies fossils
11
Paleontologist A 500
12
This is the age of a rock compared to other rocks around it
B 100
13
Relative Age B 100
14
This is created when magma cools and hardens within the Earth’s surface
B 200
15
Intrusion B 200
16
This is created when lava cools and hardens on the surface of the Earth
B 300
17
Extrusion B 300
18
This law states that the oldest rock layer is found at the bottom and each higher layer is younger than the layer below it B 400
19
Law of Superposition B 400
20
These fossils help geologists match the ages of rock layers.
The fossils were created by organisms that were only one Earth for a relatively short period of time Trilobites existed for 6% of Earth’s history B 500
21
Index Fossil B 500
22
When the amount of radioactive element decreases during radioactive decay, what happens to the amount of the stable element? C 100
23
Increases C 100
24
This is the time it takes for half of the radioactive atoms to decay in a radioactive element
25
Half-Life C 200
26
This occurs when the elements of a radioactive element break down into a stable element.

Radioactive Decay C 300
28
DAILY DOUBLE DAILY DOUBLE C 400
