According to the principle of superposition, where are the oldest rocks found?
Scattered throughout the layers
At the bottom of rock layers
In the middle of rock layers
At the top of rock layers
What does the principle of original horizontality state?
Most rock layers are deposited horizontally
Sediments are always deposited in circular patterns
Rocks can only form in water
Rocks are always deposited vertically
What is the term for the age of rocks compared to other nearby rocks?
Absolute age
Relative age
Geologic age
Chronological age
What is mass extinction?
A period of climate change
The formation of new species
A sudden disappearance of many species
A gradual change in species
Which of the following principles states that sediments are deposited in large, continuous sheets?
Superposition
Lateral continuity
Inclusions
Original horizontality
What is the main cause of erosion according to the text?
Wind
Water
Streams
Gravity
What do fossils help geologists determine?
The types of minerals
The composition of rocks
The history of Earth
The age of the Earth
What is the significance of fossils found in the oldest layers of rock?
They are not useful for dating
They indicate mass extinction
They are of relatively simple organisms
They are complex organisms
What does the principle of inclusions indicate?
The rock containing pieces is younger
The rock containing pieces is older
Inclusions are irrelevant to age
Both rocks are the same age
How long does Earth's history stretch according to scientists?
460 million years
4.6 billion years
460 thousand years
4.6 million years
What did Hutton's observations lead to the development of?

Weathering
Deposition
Sedimentation
Erosion
Which of the following is an example of a geologic process that occurs today?
Volcanic eruptions
Creation of fossils
Erosion by streams
Formation of new planets
What is the main focus of the principle of uniformitarianism?
All geological changes are catastrophic
Geologic processes today are similar to those in the past
Current processes are different from past processes
Geologic processes are random
What happens to sediments as they come over each other?
They increase in weight and compress
They dissolve in water
They become fossils
They evaporate
What is the role of gravity in the processes discussed?
It has no effect
It aids in erosion
It causes weathering
It only affects water flow
What is the relationship between the complexity of fossils and their age?
Older fossils are more complex
Younger fossils are simpler
Older fossils are simpler
Fossils do not indicate age
