Geological Dating and Depositional Sequences Quiz

What is the primary task for part A of Exercise 12?

• To identify the depositional sequences

• To define the contacts between formations

• To complete parts E and F

• To date the rocks at each location

Where can you find the fossil data sheets needed for identifying fossils?

• Pages 170 to 202

• Pages 189 to 196

• Pages 174 to 188

• Pages 197 to 201

What should you do if a fossil is not listed in the textbook?

• Research its age using the species name

• Use the family name to find its age

• Ignore the fossil

• Use any available name to find its age

How do you determine the age of a rock formation?

• By overlapping the age ranges of all fossils

• By the number of fossils present

• By the oldest fossil found

• By the youngest fossil found

What should you do if a fossil's age range does not match others in the same location?

• Assume it's correct and proceed

• Ignore the fossil

• Use it to date the formation

• Recheck the identification

Which depositional sequence corresponds to the Permian period?

• Sauk

• Tippecanoe

• Zuni

• Absaroka

What should you do if a location's age falls between two depositional sequences?

• Ignore the location

• Assign it to the earlier sequence

• Assign it to the later sequence

• Split the location between the two sequences

What type of contact is present if layer A dates to the Cambrian and layer B to the Ordovician?

• Disconformity

• Fault

• Conformable

• Unconformable

What indicates a fault contact between two layers?

• Rocks are missing between layers

• Layers are parallel

• Younger rocks are below older rocks

• Older rocks are below younger rocks

Which type of unconformity involves missing rock layers?

• Disconformity

• Angular unconformity

• Non-conformity

• Paraconformity
