One type of fish fossil is found only in a rock layer near the bottom of a canyon, while a different kind of fish fossil is found only in a rock layer 4,000 feet higher, near the top of the canyon. Which statement would a scientist most likely offer to explain this situation? A.) The fish in the lower layer lived in the deep sea. While the other fish lived in shallow water. B.) The fish in the upper layer lived a healthier life than the other fish. C.) The rock in the lower layer is denser than the rock in the upper layer D.) The rock in the upper layer must have formed in freshwater E.) The fish in the upper layer lived more recently than the other fish. The Geologic Time Scale is a systematic chronological dating process that relates geological strata to time. This methodology is commonly used be geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that once occurred in history. Which of the following statements can be considered true about the Geologic Time Scale? A.) The geologic Time Scale is used to establish Greenwich Mean Time (GMT) which reflects the time measured on the Earth’s zero-degree line of longitude, or meridian in different parts of the world. B.) The geologic Time Scale is the establishment of nomenclature of rocks according to the relative mineral hardness. C.) The Geologic Time Scale uses a radioactive carbon dating method to determine a specified geologic time spam. D.) The Geologic Time scale is an effective way of keeping careful records of the humanity’s historical events that shaped the planet’s political and socio-cultural landscape over the years. E.) The Geologic Time Scale is the unit of measurements designed to quantify the time spent by certain specie to evolve based on recorded written history by early people.
