Natural Science Study Guide

Time Determining the age of the earth pose the methods utilize for determining the age of the earth, what separately method identifys, and when It Is appropriate to use each of them. Including Principles of uniformity, Horizontally, Superimposition and Cross cutting relationships Erosion, Deposits and unconformity Radiometric dating, Carbon 14 Dating & use of the Geomagnetic Timescale Fossils influence and differentiate between Paleontology and Archaeology Define fossils and identify/ break the different types that argon commonly found. explicate the processes elated to the forming of various types of fossils (e. G. Molds & casts, how Petrified fossils are formed) geologic Time Scale Eons Identify the Eons and their associated major events. Eras Identify the eras and their associated major events. Periods Identify the various cessations, their relationships to each other and the Eras, and their associated major events. Key will be to identify what does/doesnt belong in each tim e period. Example 1 What type of Organism would you NOT expect to see during the Devotion period?A) insects, B) plants growing on background, C) Jailers fishes, D) Mammals. Example 2 During which Era did the Dinosaurs dominate the land? A) Cenozoic, B) Mesozoic, C) Paleozoic, D) Permian. (Note, why, if included would Jurassic NOT be the correct answer? take just about it ) Video How the Earth was Made What induction did the Burgess Shale reveal? What effect did rolling Oxygen levels dupe on life In the oceans and on land? How were the coal deposits formed? When did the largest extermination of life ( 90%) elapse and what do researchers think caused it?What emerged as the dominant species after this mass extinction? What is the relationship between diamonds and volcanoes? What do researchers believe killed off the dinosaurs? (hint, its NOT the aforesaid(prenominal) thing that caused the largest extinction ). What evidence is there to frequent this hypothesis? What is the key Layer? What group emerged as the dominant species after the dinosaurs went extinct? wherefore? What do Glaciers have to do with rock formations in Central putting green? From What Darwin Never Knew Video his start at being a natural scientist? How did he develop his idea of Decent with modification? What was the evidence that he used? What was Darnings view of natural infusion and how it worked? What evidence did the pocket fawn of Arizona provide when the researchers started examining its genome? What did the Human Genome project reveal about our species sexual intercourse to others, such as chickens, flies, corn, mice and monkeys? What is revealed through the process of embryonic development that supports the possible action that we all have a common ancestor? What are dust Plan, switch and boss genes? What do they do? What evidence do we have of their roles and how they work?How did the researchers investigate them and what did their research reveal? What are the broader implications of these findings? Evolution & inbred Selection Chapter 21 Define and differentiate between Evolution and cancel Selection. What is natural selection and what role does it play in Evolution? Explain what is meant by Survival of the exittest (hint, it doesnt necessarily mean being the strongest or most athletic). Identify, and explain the various sources of genetic variability and the roles they play in evolution. What are acquired traits?How are they acquired and what effect do they have on evolution? What has to return for advantages genes to be rid ofed on to the next generation? What is the science of Epigenetic revealing about the interaction between the environment and our inherited genes (as well as what we pass on)? Natural Selection Describe the role of selecting agents in natural selection and evolution. Be prepared to provide or identify examples of traits that can be (or have been) selected For or Against. **What does the Hardy-Weinberg ideal represent and how is it used?For the Null speculation of this model to be correct (I. E. No changes is occurring), a number of conditions essential be met. Identify the conditions, explain what it would take to violate these conditions, and provide evidence and or examples f what happens in the real world. Does the real world fit this model? Why or why not? What are the implications of the Hardy-Weinberg model for Evolution? What evidence do we have that Evolution occurs in lower-ranking steps. Explain not only the evidence, but how each example provides support for, or ties into the theory of Evolution.
