Step by step
Solved in 2 steps
- (1) What is the most common way for a dead organism to avoid decomposition? (2) Why do researchers look for fossils in places that are now dry and barren instead of other places like forests or grasslands? (3) What kind of dating from the lecture or textbook would be the best method for finding the number of years ago when a volcanic rock was formed? (4) Why is the pelvis of a biped shorter and wider than the pelvis of a quadruped? (5) Does the overall shape of Lucy’s pelvis resemble the human pelvis or the chimpanzee pelvis more? Do not think of the size, but compare the outlines of each bone. This is Lucy's skelton below.Researchers looking for fossils of the earliest life forms face many hurdles. For example, few sedimentary rocks date back more than 3 billion years. Explain why so few remaining samples of these early rocks remain.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…

(Give three)We live in the Cenozoic era, and scientists know more about this era and the epochs it’s divided into than any other time period. Why is this? A. We know more about the Cenozoic era because this is the only era that has had a wide diversity of species living on Earth. B. We know more about the Cenozoic era because this is the most recent time period in the history of the Earth, and we have more information available to study. C. We know more about the Cenozoic era because the planet’s poles reversed magnetic fields at the beginning of this era. D. We know more about the Cenozoic era because fossils don’t exist to document previous eras.What do you think geologists would find in the rock record as evidence of human life today million years later?
