3
What kinds of things can we infer from studying fossils?
How an organism died
The diversity of different organisms that lived in an area
How organisms became extinct
Exactly what an organism looked like when it was alive
4
Which layer is older than layer C?
Layer B
Layer C is the youngest
Layer D
Layer A
5
Give an example of "absolute age".
Mr. Turner is younger than Ms. Taylor
Mr. Coovert is older than Ms. Taylor
Ms. Taylor is older than her students.
Ms. Taylor is 28 years old.
6
Which feature is older, A or B?
B
A
Not enough information
A and B are the same age
7
The impression or cavity of a past living thing, left in sedimentary rock
cast fossil
mold fossil
carbonization fossil
fossil resin
8
Which layer is older, B or C?
B and C are the same age.
C
B
Not enough information
9
Which layer is the oldest?
Layer A
Layer C
Layer B
Layer D
10
When deciding the age difference between layer D and E, which law do you use?
law of crosscutting
Not enough information to tell
law of inclusion
law of superposition
11
When determining the age difference between layers B and C, which law do you use?
law of inclusions
none of these
law of superposition
law of crosscutting
12
Which feature is older, D or E?
D
Not enough information
D and E are the same age
E
13
What about a fossil would tell you about its diet, like if it's a carnivore or herbivore?
the strata it is found in
its fur
Its teeth
its claws
14
What kinds of things do NOT fossilize well?
shells
the teeth of an organism
the hard parts of organisms, like bones
The soft part of organisms or organisms with only soft parts
15
What does horizontal mean?
diagonal
cross-cutting
side-to-side, or going the same way as the horizon
up and down
16
What is the basic cause of extinction of species over Earth's history?
meteor strike
climate change
starvation
lack of shelter
17
What is the law of superposition?
rock fragment inside a rock layer is older than the layer
old rock layers are on the bottom and new layers are on top
new rock layers are on the bottom and old layers are on top
a layer cutting across other layers is NEWER than the layers
18
This type of fossil leaves a dark film or stain on the sedimentary rock.
mold fossil
carbonization fossil
cast fossil
trace fossil
19
What does "absolute age" tell about fossils and rock strata?
The actual age in numbers of rock strata or fossils
The half life of a fossil
How old fossils are compared to other fossils.
The age determined by the strata of sedimentary rocks
20
What would give an organism the best chances of becoming a fossil after it dies?
Slow burial, soft body parts, high heat, low pressure, time
Quick burial, soft body parts, low heat, high pressure, time
Slow burial, hard body parts, high heat, low pressure, time
Quick burial, hard body parts, low heat, low pressure, time
21
Which layer is the newest?
Layer A
Layer D
Layer C
Layer B
22
What does "relative age" tell about fossils and rock strata?
How old fossils are compared to other fossils
The age determined by radiometric dating
The half life of the rock or fossil
The age of a fossil or rock as a number
23
What is the law of crosscutting?
Rock fragment inside of a rock layer is OLDER than the layer
A feature cutting across the layers is NEWER than the layers
A feature cutting across the layers is OLDER than the layers
The oldest rock layer is on bottom, the newest layer on top
24
Fossilized footprints, nests, burrows, or poop.
carbonization fossil
Trace fossil
cast fossil
mold fossil
25
Which is an example of "relative age"?
7th graders are usually 12-13 years old
Ms. Taylor is older than her students
There are 1100 students at Belton Middle School
Ms. Taylor is 28 years old
26
What kinds of things fossilize well?
none of these things
the soft parts of organisms, like organs
the hard parts of organisms, like bones
the hair of an organism
27
What are used to determine when different time periods begin and end?
Index fossils
fossil record
geologic time scale
rock strata
28
If a species no longer exists, what do we call it?
dead
Extinct
preserved
endangered
29
Insects trapped in sticky substance secreted from a plant is preserved as the substance hardens
carbonization fossil
trace fossil
tar fossil
fossil resin
30
The fossil caused by an organism dying and the cavity being filled in by rock, sand or minerals
mold fossil
Cast fossil
fossil resin
carbonization fossil
31
Which layer is younger than layer B?
Layer A
Layer D
Layer B is the youngest
Layer C
32
What is the law of inclusions?
A crosscutting layer is NEWER than the layers it cuts across
Rock inside other rock is NEWER than the rock surrounding it
the bottom layer of rocks are older than the top layers
Rock inside other rock is OLDER than the rock surrounding it
33
When deciding the age difference between A and B, which law do you use?
none of these
law of crosscutting
law of superposition
law of inclusion
34
What are fossils?
Preserved remains of plant and animals from the distant past
layers of rock, or strata
a type of sedimentary rock
anything that has ever died and decayed
