Read each question carefully and answer to the best of your ability. Refer to your knowledge of the Law of Superposition and related geological principles.
1. Which of the following best describes the Law of Superposition?
Sedimentary layers are originally deposited in horizontal layers.
In an undisturbed sequence of sedimentary strata, the oldest layer is at the bottom and the youngest is at the top.
Faults and igneous intrusions are younger than the rocks they cut through.
Identical fossils found in different strata indicate the strata are of the same age.
2. The Law of Superposition is primarily used for which type of geological dating?
Absolute dating
Radiometric dating
Relative dating
Carbon dating
3. The Law of Superposition is a fundamental principle of , which is the study of layered rocks.
4. According to this law, any given layer of rock is than the layer above it and than the layer below it, assuming no disturbance.
5. The Law of Superposition can be applied accurately even in areas with significant tectonic activity and folding.
True
False
6. The Law of Superposition was first proposed by Nicolas Steno in the 17th century.
True
False
7. Observe the image of sedimentary layers. If Layer A is at the bottom and Layer D is at the top, which layer is the oldest and which is the youngest? Justify your answer using the Law of Superposition.
8. Describe a geological scenario where the Law of Superposition might be misleading or difficult to apply. What other geological principles would you use in such a case?
