  28. 28. Paleontology<br />The study of past life<br />
  29. 29. 1. Important Words!<br />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.<br />Uniformitarianism – the idea that the same geologic processes shaping the Earth today have been at work throughout Earth’s history<br />
  30. 30. Rocks Record Earth History<br />2. Discovering Earth’s History <br /> Rocks record geological events and changing life forms of the past.<br /> 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.<br />
  31. 31. There are two main ways to determine how old a rock or fossil is:<br />3. How old is it??<br /><ul><li>Relative dating
  32. 32. Absolute dating</li></li></ul><li>4. Relative vs. Absolute Dating<br />I. Relative dating – determining whether an object or event is older or younger than other objects or events<br /> A. Superposition<br /> 1. Older rocks are under <br /> newer rock<br /> 2. Can only determine relative time<br />
  33. 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.<br />
  34. 34. II. Absolute Dating – the process of establishing the age of an object by determining the number of years it has existed.<br /> A. Radioactive decay – the process in which a radioactive isotope tends to break down into a stable isotope of the same element.<br />
