MS LS4 1

Isla, Zoe, and Evelyn went on a field trip to a geological museum. They learned that the geologic time scale is a record of....

• the history of fossils

• the history of rocks

• the history of rock layers and fossils

• geologist notes

Aiden, Ethan, and Kai are studying for their geology exam. They come across a section on the Geologic Time Scale. Ethan asks, 'What is the primary purpose of the Geologic Time Scale?'

• To categorize different types of rocks

• To map the history of life forms and geological events in Earth's history

• To predict future geological events

• To measure the age of the universe

During a field trip, Hannah, Michael, and Harper found a fossil in a rock layer. What does the presence of this index fossil indicate about the relative age of the rocks in that layer?

• It indicates a specific time period, as index fossils are found in only one layer of rock

• It indicates a range of time periods, as index fossils are found in multiple layers of rock

• It indicates the wealth of the rock layer, as index fossils are rare and valuable

• It makes the rock layer easy to identify, as index fossils are large and easily visible

During a field trip, William, Ethan, and Abigail observed a sequence of sedimentary rock layers. What does the Law of Superposition state about the age of these rock layers?

• The topmost layer is the oldest

• The bottommost layer is the oldest

• All layers are the same age

• The age of the layers cannot be determined

Which of these cases provides embryological evidence that two species share a common ancestor?

• two species with very similar DNA

• two species with different body structures

• two species with different structures that have similar functions

• two different species with similar patterns of early development

Two species might have similar skeletal structures that have different functions. What do these types of structures suggest about the relationship between the two species?

• Common structures with different functions suggest that the species live in the same habitat.

• Common structures with different functions suggest that the species do not share a common ancestor.

• Common structures with different functions suggest that one of the species never learned how to use the structure properly.

• Common structures with different functions suggest that the species share a common ancestor that also had a similar structure.

This image shows the development of various organisms and how they share a common ancestor because of similarities in development.  It is called:

• homologous structures

• evolution

• natural selection

• embryology

Tara is comparing the embryos of parrotfish and salamanders. Although the adult organisms look very different, the embryos follow similar developmental pathways. What does this suggest?

• that parrotfish and salamanders are found in the fossil record

• that parrotfish and salamanders have the same genetic makeup

• that parrotfish and salamanders likely share a common ancestor

• that parrotfish and salamanders use their organs for different functions
