The correct response is all of the above.
All listed options—fossil evidence, glacial deposits, and the match-up of landforms, rocks, and other resources—provide evidence supporting the theory of continental drift.
The theory of continental drift describes the movement of landmasses on Earth's surface.

The cake layer on the bottom of the cake is
older than the cake layer on the top of the
cake.
Today, my dog Max turned 5 years old.
In a rock, a Carbon-14 isotope underwent one
half-life therefore the rock is 5,730 years old.
The highest/top sedimentary rock layer at The
Grand Canyon is younger than the rock layers
below it.

Here are the matches for each statement:
- Relative Age: The cake layer on the bottom of the cake is older than the cake layer on the top of the cake.
- Absolute Age: Today, my dog Max turned 5 years old.
- Absolute Age: In a rock, a Carbon-14 isotope underwent one half-life; therefore, the rock is 5,730 years old.
- Relative Age: The highest/top sedimentary rock layer at The Grand Canyon is younger than the rock layers below it.
So the final matches would be:
- Relative Age: 1 and 4
- Absolute Age: 2 and 3
Sadie the scientist has been studying a sedimentary rock layer. Her recordings can be seen in the diagram below:
Sadie is surprised to see that only the bottom layer has fish fossils that appear. Why has there been a shift from fish fossils to cactus fossils in the sedimentary rock layer? Choose 2 options from the list below that support Sadie's research.

The two options that support Sadie's research regarding the shift from fish fossils to cactus fossils in the sedimentary rock layer are:
- Due to the Law of Superposition the fossils in the bottom layer are older.
- The environment conditions have changed over time.
These choices explain that the bottom layer of sediment is older and that the shift in the types of fossils indicates a change in environmental conditions from an aquatic setting (with fish) to a terrestrial one (with cacti).
