1 Chapter 15 The Rock and Fossil Record

2 Choose the right answer!  Which Process is responsible for increasing dissolved carbon dioxide levels in the oceans? A. Respiration B. Photosynthesis C. Upwelling D. Preserving Estuaries  In what pH range are most aquatic organisms most likely to remain healthy?  A. 2.0 to 4.0  B. 3.0 to 5.0  C. 7.0 to 8.5  D. 8.5 to 10.5

3  A farmer observes that a nearby pond has an overgrowth of algae. Which condition is most likely to be present in the pond.  A. The water is more acidic than normal.  B. The water contains increased levels of fertilizers and other nutrients  C. The water has low turbidity  D. The water has a low nitrate level.  What is the main point of water quality standards set by states and the federal government?  A. To make sure water remains clean and safe for use  B. To create new bodies of water from wastewater  C. To reduce the number of oil spills from tankers  D. To ensure that all wastewater undergoes the same treatment process

4 Earth’s Story  How do mountains form?  How is new rock formed?  250 years ago these questions were being asked and researched.

5 James Hutton  Theory of the Earth  The key to understanding Earth’s history is all around us…  Uniformitarianism-the same geologic processes shaping the Earth today have been at work throughout Earth’s history

6 Uniformitarianism vs. Catastrophism  Geologic processes take millions of years.  Catastrophism- principle that states that all geologic change occurs suddenly.  Catastrophes?

7 Charles Lyell  Principles of Geology ( )  Challenged the principles of catastrophism  Geologic change happens gradually.

8 Modern Geology  Geology through a happy medium  Evidence through craters and recreations

9 Paleontology  The study of past life  Use of fossils as data collection  Invertebrate Paleontologist  Paleobotanist

10 Letter to a Scientist  Write a letter to Charles Lyell, James Hutton or Stephen Gould  Briefly explain the position of each scientist in reference to Geology  You should explain why you agree or disagree with the scientist’s theories.  See pages  Conclude your letter with at least two questions.

11 Working with a partner; Design a poster announcing a debate between Catastrophist Uniformitarian Use phrases and pictures Summarize the major points of both sides
