Chapter 19, Problem 1DAA
The Changing Earth Studies of ancient rocks and fossils can reveal changes that have taken place during Earth’s existence. FIGURE 19.13 shows how asteroid impacts and the composition of the atmosphere are thought to have changed over time. Use this figure and information in the chapter to answer the following questions.
FIGURE 19.13 Charges in the abundance of asteroid impacts (green), atmosphere carbon dioxide concentration (pink), and atmospheric oxygen (blue) over geologic time.
1. Which occurred first, a decline in asteroid impacts, or a rise in the atmospheric level of oxygen (O2)?

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?
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
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. Alternative: The rate of extinction would be greatest immediately after the asteroid
strike.
Null: The rate of extinction…

- What evidence did Lord Kelvin and Charles Darwin each use to support their conclusions about the age of the Earth? Kelvin's evidence Darwin's evidence Answer Bank Water bodies accumulate sediment in a predictable manner, and the rate of accumulation is measurable. The temperature of rocks in mine shafts shows how long the solid Earth has been cooling. Counting sedimentary rock layers in geologic formations gives an estimate of the rocks' ages. Heat moves through a solid, such as rock, at a predictable and measurable rate as the solid cools.arrow_forwardGive 1 reason from the reading that shows that there are no life forms on Venus.arrow_forwardEarth 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.arrow_forward
