Unit 4 Review - Study Questions

Name: ______________________ Period: ______ Date: ______________

Answer each question in complete sentences. Use evidence from the reading to support your response. This assignment is due at the beginning of class on Friday.

Summarize the main argument presented in the second section of the chapter.
Explain how the author uses supporting evidence, and identify at least two examples from the text.
Compare the two perspectives discussed in class. Where do they agree?
What conclusion does the author reach, and do you find it convincing? Why or why not?

The main argument in the second section is that the changes described were driven less by any single event than by a slow shift in conditions over time.

Results

Mass fell steadily across all six trials.
Temperature rose fastest between 60 and 120 seconds.
