2. Identify five ways in which different types of fossils form.
3. Describe three types of trace fossils.
4. …show more content…
Explain why the fossil record is an incomplete record of the history of life on Earth.
5.
Paleontologists can use the fossil record to prove which of the following statements?
6. Explain how fossils can be used to determine the history of changes in environments and organisms.
7. Explain how an index fossil can be used to date rock.
Section 3
1. Use era, period, and epoch in the same sentence.
2. Explain how geologic time is recorded in rock layers.
3. Identify the major time intervals that the geologic time scale represents.
4. Identify two types of environmental changes that cause mass extinctions.
5. A mass extinction event occurs when there is an significant decrease in the number of species in a relatively short period of time. Which of the following conditions has been the most frequent cause of mass extinction events?
6. Explain how the number of animal species has both increased and decreased during Earth’s history.
7. Identify two unique traits that may have helped mammals survive the mass extinction at the end of the Mesozoic era.
Answers
Section 1
1. Uniformitarianism assumes that geologic change is slow. Catastrophic assumes that geologic change is fast. Paleontology is a science that uses fossils to study past life.
2. Uniformitarianism is assumed that geologic change happens slower that
catastrophic.
3. Geology used to be based on catastrophism. Now the geology is based on uniformitarianism.
4. d. Relative dating uses the half-lives of rock layers to determine the age of fossils.
5. The columns are arranged from oldest to youngest.
Section 2
1. The two main types of fossils are trace fossil and index fossil.
2. Fossils in rocks – When organisms die and are quickly buried in sediment
Fossils in amber – When an insect is caught in sticky tree sap and hardens
Petrifaction – When minerals replace an organism’s tissue
Fossils in asphalt – When organisms are trapped in pools of asphalt
Trace fossil – any naturally preserved evidence of animal activity
