The diagram below shows a cross section of different rock layers. According to the law of superposition, the rock layer above another rock layer is younger than the one below.
According to the law of superposition, which numbered layer is the youngest?
Layer 1
Layer 2
Layer 3
Layer 4
What type of evidence did geologists use when they were making the boundaries of the geologic time scale?
Evidence of changes in the fossil record
Evidence of changes in the early solar system
Evidence of changes in Sun’s behavior
Evidence of changes in the Moon’s orbit
Use this geologic map to answer the following question: Which Ohio city is in the region marked as “Very good to excellent” for oil and gas potential?
Cleveland
Youngstown
Columbus
Akron
If a fault has broken a rock layer, the fault is younger than the rock layer.
True
False
Which law states that a fault or body of rock, such as an intrusion, must be younger than any feature or layer of rock that the fault or rock body cuts through? -- Study the diagram on p. 250!
The law of differentiation
The law of uniformitarianism
The law of crosscutting
The law of Pangaea
Which of the following is true about index fossils?
They existed for a short period of time
They similar to any other fossil
They have a unique color
There are only a small amount of them
In the 1830s, an English scientist proposed the idea of uniformitarianism to describe the process of geologic change on Earth. Which of the following words is most closely associated with uniformitarianism?
Rare
Sudden
Gradual
Catastrophic
What law can help scientists determine the relative age of sedimentary rock layers where younger rocks lie above older rocks?
Unconformity
Superposition
Geologic columns
Trace fossils
What process do scientists use to determine that Earth is approximately 4.6 billion years old?
Catastrophism
Superpositioning of rocks
Radiometric dating
Crosscutting relationships
After scientists study ice cores, why do they study the widths of the bands within the cores?
To search for animal traces within the thickest layers
To learn how much precipitation fell during a certain time
So they can find thicker layers of gas
So they are able to determine the temperature of that period of time
What is the breakdown of radioactive isotopes into a stable isotope of the same element or another element called?
Absolute dating
Uranium-Lead dating
Element decay
Radioactive decay
How are relative dating and absolute dating different?
Absolute age is an average while relative dating is an estimate
Both give the age of the rocks within a layer
Absolute age gives the age of the rock in years while relative dating gives a comparative age
Absolute age is determined by the law of superposition while relative dating is determined by radiometric dating.
What do fossils of tropical plants found in Antarctica tell you about its location?
Antarctica is in the same location as it was in the past
Antarctica was likely closer to the equator at one point, but the continent has moved throughout Earth’s history
Antarctica has shifted from the Northern part of the globe to the Eastern part of the globe
Tropical fossils have yet to be found in Antarctica.
A fossil contains 12.5% of its original amount of carbon-14. How long ago did this organism live?
5,730 years ago (1 half life)
11,460 years ago (2 half lives)
17,190 years ago (3 half lives)
20,000 years ago (4 half lives)
Jacob has one older brother and one younger sister. He wants to explain relative dating to them using their ages as an example. Which of the following arrangements would show the concept of relative dating?
Forming a line in the order of age
Forming a line in the order of height
Forming a line in the order of weight
Forming a line in the order of birth month
How are the animals in the fossil record related to the animals that exist today?
The animals in the fossil record are very different from the animals that exist today
The animals in the fossil record are more complex from the animals that exist today
The animals in the fossil record are ancestors of animals that exist today
The animals in the fossil record are the same as the animals that exist today
Which law helps you understand that fault “J” is younger than the rocks it cuts through?
The law of superposition
The law of relative dating
Uniformitarianism
The law of crosscutting relationships
