Which of the following statements is most accurate as it relates to the Law of Superposition?
The Law of Superposition is an explanation relating to the sequence of disturbed rock layers.
The Law of Superposition is an observable fact relating to the sequence of undisturbed rock layers.

A rock climbing group reached the top of Mount Everest in the Himalayan mountains. Mount Everest is about 29,000 feet above sea level. The group leader was surprised to find fossilized marine organisms on top of the mountain. How do these fossils reflect the geologic history of Mount Everest?
Two tectonic plates of different densities caused one plate to subduct into the ocean and the other one to rise causing marine organisms to fossilize on top of Mount Everest.
Two tectonic plates of the same density caused transform boundaries to release volcanoes and to fossilize marine organisms before the Himalayan mountains were formed and uplifted.
Two tectonic plates of the same density caused a collision and pushed the plate boundaries that contained fossilized marine organisms upward forming the Himalayan mountains and Mount Everest.
Two tectonic plates of different densities caused the lighter of the two boundaries to rise above the surface and to form the Himalayan mountains, the ash of which contained fossilized marine organisms.
