Analyzing Rock and Fossil Records

Emma, Avery, and Henry went on a field trip to a geological park. They found a rock and wanted to determine its age compared to the ages of other rocks they found. This is known as the rock's

• time period

• relative age

• absolute age

• A,B,C,D,E

• E,D,C,B,A

• E,B,C,D,A

Rohan found a fossil while on a field trip and Emma found a rock in her backyard. They both want to know the age of their finds. How does the absolute age of Rohan's fossil differ from the relative age of Emma's rock?

• Absolute age is the age of Rohan's fossil that can be estimated but not determined exactly.

• Relative age is the age of Emma's rock that can be determined exactly.

• Absolute age is the age of Rohan's fossil that can be determined by comparing it to other rocks or fossils that Charlotte found.

• Absolute age is the exact age of Rohan's fossil, while relative age is the age of Emma's rock relative to other rocks or fossils that Charlotte found.

William, Aiden, and Abigail went on a field trip to a geological site. They observed Limestone, Basalt, Fault, and Siltstone formations. Can you help them arrange these features in order from oldest to youngest?

• Limestone, Basalt, Fault, Siltstone

• Siltstone, Fault, Basalt, Limestone

• Limestone, Fault, Basalt, Siltstone

• Limestone, Siltstone, Fault, Basalt

Maya and David found a fossil while on a field trip. They believe it's an index fossil and can help them determine the relative age of the rock layers in the area. Is this true?

• True

• False

During a summer vacation, Lily found an index fossil in a layer of rock in Montana. Later that year, Henry found a similar fossil in a layer of rock in Texas while on a school trip. From this, they could conclude that:

• The index fossil is a plant fossil.

• The layers of rock in Montana and Texas where Lily and Henry found the fossils are of the same age.

• The index fossil is not a reliable indicator of age.

• The layers of rock in Montana and Texas are different ages.

During a field trip, Michael, Benjamin, and Nora found small pieces of older igneous rock (E) within a layer of younger sedimentary rock. This is an example of which geological principle?

• principle of inclusions

• 
  principle of cross-cutting relationships

• principle of superposition

• principle of original horizontality
