WorksheetsL1 Quiz: Rocks and Fossils are Evidence of Earth's History
Total questions: 20
Worksheet time: 10mins
________ are the remains or traces of once-living organisms.
Sediments
Shells
Fossils
Cell structures
If you want to explore rock layers in regions where the rock is not exposed, you can:
use a drill or sonography
look for other areas that are exposed and limit your research space to ONLY areas that are visible
wait for a fault to occur and stall your research
use relative dating
True or False? High concentration of fossils in the Morrison Formation meant that more organisms lived there than in other parts of the country.
True, more fossils means more organisms.
True, the Morrison Formation is known to be the home to more species than anywhere else in the USA.
False, it just means that the conditions there were better for fossil formation at that time.
False, the Morrison Formation does not have any fossils.
How does knowledge of sedimentary rock formation help us to understand fossils?
Sedimentary rock formation do not help us understand the fossils found in them.
The rock formations help us determine absolute age of each fossil. We can tell the exact age of fossils without chemical testing.
The rock around a fossil helps scientists with forming the theory of uniformitarianism.
Knowing how the rock around a fossil is formed helps scientists draw conclusions about how the fossil formed and what type of environment the animal lived in.
The rock layer at the very top is the ______________. The rock layer at the very bottom is the ________________.
youngest; oldest
youngest; weakest
strongest; weakest
weakest; strongest
______ is any method of determining whether something is older of younger than something else.
absolute dating
relative dating
radioactive dating
chemical dating
What is a term used to describe the remains of an organism that was common and widespread but existed for only about 1 million years (or less).
relative fossil
absolute fossil
recurring fossil
index fossil
If fossils of a certain trilobite and brittle star were found in the same rock layer, what an you infer about them?
They are related species.
They like in completely different habitats.
Fossils in the same rock layer are likely the same age.
They had the exact same diet.
When some rock layers are missing and form gaps, you have a/an ____________.
unconformity
uniformitarianism
gap links
rock gaps
Which layer is the oldest?
A
B
C
D
Which layer or event happened last?
B
C
D
E
Which of the following options summarizes how this rock formation could have occurred?
Layers C, B, and A formed in that order; then intrusion D; finally E, a fault occurred.
Layers A, B, and C formed in that order; then fault E, finally intrusion D.
Layers C, B, and A formed in that order; then fault, E; finally intrusion D occurred.
Layers C, B, and A formed in that order; then fault D; finally intrusion E.
What would be a good claim for the following question:
How can scientists determine when ancient animals lived?
Scientists can determine when ancient animals lived by creating models to mimic what the animal looked like.
Scientists can determine when ancient animals lived by studying the current environment of where their fossils were found.
Scientists can determine when ancient animals lived by studying the age fossils they left behind.
Scientists can determine when ancient animals lived by studying the age of the models found in museums.
When looking at a cliff, where would be the oldest layer?
Bottom
Top
Darkest
Brightest
True or False: You can determine the age of a rock formation by how dark the top layer is.
True
False
True or False: Fossils can be found in shale and limestone.
True
False
Imagine a sandwich sliced in the middle. The slice could represent a/an ________.
rock layer
fault
fossil
index fossil
How can scientists find the absolute age of igneous rocks?
By drilling into the center of the rock.
By testing how high you can drop the rock.
By testing the ratio of unstable and stable particles in a rock sample.
By testing the ratio of its size compared to other rock formations.
True or False: Faults can cut through intrusions.
True
False
True or False: Absolute age can be determined by looking at a photo of a rock.
True
False
