8 th grade Compare fossils found in sedimentary rock to determine their relative age httpwwwbrainpopcomsciencediversityoflifefossils Standard for this lesson How can we tell what lived when. Lucy is a fossil of . Australopithecus . afarensis. , . an. . early . form of . human, . that was discovered in 1974 in Ethiopia.. Lucy is estimated . to have lived about 3.2 million years . ago.. What does Lucy tell us about the evolution of humans?. If you were to put the following events in to a time sequence of first to last, how would you do it? What else would you add?. . Go to school. Wake up. Eat lunch. Put clothes on. WHAT’S IN THE ROCKS!. Fossils found in SEDIMENTARY ROCKS. The lower the sediment layer is, the older the fossils of the layer will be.- Law of Superposition. As time elapses, more and more sediment layers form to create the layers of sedimentary rocks.. Relative Dating. Determining relative ages of rocks or strata compared to another rock or strata. . Can say which layer is older and younger but can’t say absolute age. . For example, Rock Layer A is older than rock Layer B. . If you were to put the following events in to a time sequence of first to last, how would you do it? What else would you add?. . Go to school. Wake up. Eat lunch. Put clothes on. State. . Performance Indicators. Fossils. Fossils provide a window into the past as they provide evidence about the changes that have occurred to the Earth over the 4.5 billion years of existence.. A . fossil . is the preserved evidence in rocs or soils of organisms that once existed on Earth.. Fossils. Fossils provide a window into the past as they provide evidence about the changes that have occurred to the Earth over the 4.5 billion years of existence.. A . fossil . is the preserved evidence in rocs or soils of organisms that once existed on Earth.. Earth is very, very old…. Earth’s History. The history of Earth and the ages of rocks can be investigated and understood by studying rocks and fossils.. Evidence of ancient, often extinct life is preserved in many sedimentary rocks.. Relative Dating. To . determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition.. Fossils have helped determine approximately when life first appeared, when plants and animals arrived on land, and when organisms became extinct.. CONDITIONS NEEDED FOR FOSSIL FORMATION. Whether or not a dead organism becomes a fossil depends upon how well it is protected from scavengers and agents of physical destruction, such as waves and currents.. Week 3.

Geologic Time and Evolution Earth Has a History Geologic materials record enormous changes. Earth is a complex, evolving system. Physical and biological systems continuously interact. Earth constantly changes and has done so through time. Fossils, Geologic Time, Absolute & Relative Dating, and Natural Resources Chapters 5 & 6 How Do Fossils Form? Fossils are found in sedimentary rocks like sandstone, limestone, and shale In Virginia, most fossils are
