Earth Science Chapter 10 Layered Assignments
A Trip Through Geologic Time
Alan Dewey
Wabasso High School
OBJECTIVES
1. Interpret successive layers of sedimentary rocks and their fossils to infer relative ages of rock sequences, past geologic events, changes in environmental conditions, and the appearance and extinction of life forms.
2. Use relative dating techniques to explain how the structures of the Earth and life on Earth have changed over short and long periods of time.
3. Explain how rocks and fossils are dated.
4. Understand the geologic time scale and Earth's history.

LAYER A- CRITICAL THINKING & ANALYSIS OF REAL WORLD ISSUES (15 points)
Using 2 sources, write a three
paragraph paper no longer than one page to answer one question below.
The first paragraph should be an introduction. The second paragraph
should give facts and information about your question, including pros
and cons if your question has them. The third paragraph should
give your opinion based on your research. You should list your
sources below.
____ 1. What caused the extinction at the end of the Cretaceous era that killed the dinosaurs and many other species?
____ 2. What are some pros and cons of using potassium-argon dating to date ancient rocks?
____ 3. What are some common MN fossils and what do they tell us about MN’s geologic history?
____ 4. Find articles on
two recent fossil discoveries. Write a 3-4 sentence summary on
each one for your first 2 paragraphs. The third paragraph should
include your thoughts on the articles and how they relate to what was
discussed in class. Sciencedaily.com is a good website to start
at.
