The document provides information for a science class unit on paleontology. It includes instructions for students to hand in late work, notes that midterm grades will be sent home on Friday, and provides test answers. It also outlines the unit, describes upcoming projects on fossils and tiers, and defines key terms like observation, inference and conclusion. Homework assigned is to complete Tier 1.

28. Paleontology The study of past life

29. 1. Important Words! Paleontologist – scientist who studies fossils and plants from past life and other recontructed past ecosystems, study traces left behind by animals and piece together the conditions under which fossils were formed. Uniformitarianism – the idea that the same geologic processes shaping the Earth today have been at work throughout Earth’s history

30. Rocks Record Earth History 2. Discovering Earth’s History  Rocks record geological events and changing life forms of the past.  We have learned that Earth is much older than anyone had previously imagined and that its surface and interior have been changed by the same geological processes that continue today.

33. B. Geologic column is an ideal sequence of rock layers that contains all the known fossils and rock formations on Earth arranged from oldest to youngest.

34. II. Absolute Dating – the process of establishing the age of an object by determining the number of years it has existed. A. Radioactive decay – the process in which a radioactive isotope tends to break down into a stable isotope of the same element.
