PPT-The relative ages of fossils

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. Fossil are the preserved remains or traces of living things.. They form when living things die and are buried by sediment.. They are usually found in _______________ rock. 1. . Petrified fossils: . formed by replacement.. The . unweathered. rock that lies below the lowest layer of soil. Depostion. Bedrock. delta. The decayed remains of plants and animals. a. delta. b. soil. c. humus. A large mass of deposited sediments at the mouth of a river. Power DECENTRALIZED from empire. . 3 Important Elements of Middle Ages (Dork Ages) . Political- Feudalism. King. Lord/Noble/Vassal. Knight. Peasants. Serf (tied to land, was not sold). ECONOMIC. MANORIALISM- basic economic arrangement during Middle Ages which rested on set of rights and obligation between a lord and his serfs. Lord provided serf with housing, farmland, protection from bandits. Serf tended the lord’s lands, cared for his animals, went on Starbucks runs. Dr. . Jagdish. . kaur.

The evolutionary timeline is divided into sections of time called eras – which are then divided into smaller units of time called periods.. 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. Part II. Types . of Fossils:. Molds. . Casts. Trace fossils. Petrified . fossils. Body. Mold. . fossils. - . a visible empty . space . that was left after an . organism . was . buried in sediment and then . Molds and Casts. Carbon Films. Preserved Remains. Trace Fossils. Petrified Fossils - . How do they form?. Mineral rich water soaks into cracks and crevices. Minerals “precipitate” and fill the spaces. 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 are the . preserved remains . or traces of . living. things. Most fossils form when . living. things die and are buried by . sediments. . The . sediments. slowly harden into . rock. 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.. Fall 2012. Training Presentation. IA. Introduction. Tell Students:. The . Geologic Time Scale . covers Earth’s entire history. It is divided into 4 major time intervals called eons. The eons are not the same length, but are based on major events. SCHEDULE. GROUP . A 12/3/18 . ASHTON CALHOUN. EMMANUEL MARIN. HANNAH REEVES. GROUP B 12/5/18 . CAROLINE GRACE EARLE. ANDREW CALLAWAY.
