Textbook Question
Chapter 15, Problem 3FIB
Georges Cuvier espoused a concept called ______ to explain layers of rock with embedded fossils. Charles Lyell, building on the work of James Hutton, proposed an alternative explanation called ______, which states that layers of rock and many other geological features can be explained by gradual processes that occurred in the past just as they do in the present. This concept provided important support for evolution because it required that Earth be extremely ______.

Earth is about 4.5 billion years old. In order to characterize the events that happened in this very long time scale, scientists have developed the geologic time scale. Here, the age of Earth is divided into (1), which in turn divided into (2), and are further subdivided into (3). The geologic time scale is so-called since the different subdivisions are based on the fossil record.
Scientists are examining the possible role of a large asteroid in the cretaceous mass extinction event. A large asteroid strike would likely have caused rapid climate cooling and the diffusion of sunlight. which of the following statements are the best null and alternative hypotheses when scientists look at the geologic evidence of extinction related to the asteroid strike?
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.

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.arrow_forwardIn 1983, a team of scientists discovered a fossilized bone of a giant bird when excavating land in Brazil. After studying the fossil, the team thought that the bird was unique to South America but had been extinct for millions of years. Many years later, another fossil from the same giant bird was found in Nigeria. The two fossils were formed in rock that was very similar to one another. Look at the land masses on the map. What can the scientists conclude? a The land masses were once connected. b These were two different types of giant birds, even if their fossils look identical. c The fossils date to different time periods and appear in separate regions. d The giant bird migrated to South America, because the bones were later found in Nigeria.arrow_forward
- The largest and most deadly of all Mass Extinctions in the history of Earth came at the end of the Period, when only 5% of the existing species survived. Nobody knows exactly what caused this event, so it remains a mystery to this day. Quaternary Devonian Ordovician Permianarrow_forwardIt has been suggested that the current time should be made into a different period. In other words, it should not have been part of the Holocene period due to the extreme changes man has made to the earth. If you were a scientist tasked to give a name to the period of today what name would you give it and why?arrow_forwardA scientist has a fossil that was found in a layer of rock close to Earth’s surface. He believes that the fossil is around 12,000 years old. Which method would best allow the scientist to confirm the actual age of the fossil? finding another fossil in a deeper layer of rock finding another fossil in the same layer of rock using carbon/nitrogen absolute dating using potassium/argon absolute datingarrow_forward
- Using radioactive isotopes to determine the age of a fossil is known as radiometric dating. How might radiometric dating provide support for the theory of evolution by natural selection? Hint—Consider the age of fossils with respect to the overall fossil record (the entire collection of data regarding fossils and the age of Earth). “Navy coffee” is where the coffee is brewed strong and a bit of salt is added. What is special about water that allows you to put sugar or salt in your coffee? To help answer this question, consider the opposite situation: Why do salt scrubs that you buy in a high-end spa consist of large salt crystals in oil?arrow_forwardScientists are examining the possible role of a large asteroid in the Cretaceous mass extinction event. A large asteroid strike would likely have caused rapid climate cooling and diffusion of sunlight. Which of the following statements are the best null and alternative hypotheses when scientists look at the geologic evidence of extinction related to the asteroid strike? Null: The rate of extinction would be steady over the entire length of time the climate was altered. Alternative: The rate of extinction would be greatest immediately before the asteroid strike. Null: The rate of extinction would gradually decrease over the entire length of time the climate was altered. Alternative: The rate of extinction would be at its lowest immediately after the asteroid strike. Null: The rate of extinction would be steady over the entire length of time the climate was altered.
