answer the following questions about the picture of the two columns: 18. looking at the fossil evidence; which two layers are the same age?______ 19. which layer is then oldest? ______ 20. which layer is the youngest? ______ look at the illustration to the right to answer the following questions: 21. in relative dating, which layer is the oldest? ______ 22. which layers is the youngest? ______ 23. what has happened to this rock layers to make it curve? ______ use the figure below to answer questions
Answer
Explanation:
Step1: For question 18, same - age layers have similar fossils.
Layers A and D have similar fossils, so they are the same age.
Step2: For question 19, in undisturbed rock layers, the bottom layer is the oldest.
In Column I, layer C is at the bottom, so C is the oldest.
Step3: For question 20, in undisturbed rock layers, the top layer is the youngest.
In Column I, layer A is at the top, so A is the youngest.
Step4: For question 21, in undisturbed rock layers, the bottom layer is the oldest.
In the lower figure, layer E is at the bottom, so E is the oldest.
Step5: For question 22, in undisturbed rock layers, the top layer is the youngest.
In the lower figure, layer A is at the top, so A is the youngest.
Step6: For question 23, rock layers curve due to tectonic forces.
Tectonic forces such as compression cause rock layers to fold and curve.
Answer:
- A and D
- C
- A
- E
- A
- Tectonic forces (compression)
