(page 2)
How does geological time help scientists keep track of events in Earth's history? (page 2)Describe strata. (page 2)Which organisms on the geologic time scale are now extinct? (page 2)What are the two main processes scientists use to measure the age of Earth and its parts? (page 3)What is another name for radioactive dating? (page 3)How do we use relative dating to determine the age of a fossil, artifact, or rock layer? (page 4)According to the law of superposition, where would you find objects with an older
relative age? (page 4)Name two index fossils. Why are these fossils important to the practice of relative aging? (page 4)How do we use radioactive dating to determine the age of a fossil, artifact, or rock layer? (page 5)If you needed to find the exact age of an object, which age analysis process would you use? Why?(page 5)How does radioactive decay help scientists determine the exact age of an object? (page 5)Carbon-14 is best used to find the age of: (page 5)Uranium-235 is best
used to find the age of: (page 5)What is one limitation of radioactive dating? (page 5)Fossils Video:Key Questions and TermsNotesDescribe how a fossil forms. (page 2) videoName two things a fossil can show scientists.(page 2) videoNASA Harnesses Half-Life Video:Key Questions and TermsNotesWhat are some practical uses for radioactive substances? (page
5) videoWhat is an isotope? (page 5) videoWhat is half-life?(page 5) videoCrystal Springs Preserve Video:Key Questions and TermsNotesWhat clues were used in the video to determine the estimated age of the fossil? (page 6) videoWhat is bay bottom chert? (page 6) videoHow could you determine absolute age of this fossil? (page 6) video
03.02 Layers of the Earth Guided NotesObjectives:In the lesson, you will:●identify and describe the layers of Earth and the interactions between among them●describe the motion of convection currents inside of Earth●investigate the effects of temperature, pressure and density on the core of the EarthBig Ideas:Key QuestionsNotesName and describe the two ways scientists learned about the solid and liquid layers of Earth. (page 2)What is the direct evidence that scientists have that there is a liquid layer of Earth? (page 2)How do scientists use seismic waves to determine that Earth has solid and liquid layers? (page 2)
Describe the different layers of Earth. Include composition and temperature. (page 3) Video●Crust●Mantle●Outer Core●Inner CoreIn which layer can you find tectonic plates? (page 3) VideoDescribe the difference in composition between the two crusts. (page 3) Video●Continental Crust●Oceanic CrustDescribe the three layers of the mantle. (page 3) Video●Lithosphere●Asthenosphere
●MesosphereDescribe the movement of the asthenosphere. (page 4)Describe the movement of convection currents. How does that movement help move tectonic plates? (page 4)Describe the geological event that occurs during each plate movement.(page 4)●Plates move apart●One plate goes under the other●Plates move togetherDescribe how temperature, pressure and density
impact the core of Earth. (page 5)
03.03 Plate Tectonics Guided NotesObjectives:In the lesson, you will:●explore the theory of plate tectonics●describe the movements of Earth's crustal plates●differentiate slow and rapid changes in the earth's surface as a result of tectonic plate movementsBig Ideas:Key Questions and TermsNotesHow was the theory of plate tectonics developed?(page 2)What is Pangea? (page 2)Who came up with the continental drift theory? What does it state? (page 2)What empirical evidence supports the theory of plate tectonics? List and explain all four.
(page 2)Why was Wegener's theory of continental drift rejected? (page 2)Explain the relationship between the continents, the lithosphere, and the asthenosphere. (page 3)What new evidence led to the theory of plate tectonics? Use the Evidence interactive to help you. (page 3)Where are the tectonic plates located on Earth?(page 4)What are faults? Where are faults found? (page 5)Describe the three main types of plate boundary interactions: (page
5)●Divergent boundaries:●Convergent boundaries:●Transform boundaries:What types of geological events can the following interactions produce? (page 5)●Divergent boundaries:●Convergent boundaries:●Transform boundaries:What is accretion? (page 5)What is sea floor spreading? (page 5)What happens during subduction? (page 5)
How do the tectonic plate interactions build mountains and cause volcanic eruptions? (page 6)Describe each type of mountain. Include the type of boundary where they are likely formed and characteristics of each. (page 6)●Folded Mountains●Fault-block MountainsDescribe each type of volcano. (page 6)●Shield volcano:●Cinder volcano:●Composite volcano:What is the difference between body waves and surface waves? (page 7)List some characteristics of
each type of seismic wave. Include what type of material (solids, liquids, or both) each can travel through. (page 7)●Primary wave:●Secondary wave:●Love wave:●Rayleigh wave:How do tectonic plate interactions cause earthquakes? (page 7) (top)Tectonic Plate Movement Video: (page 4)Key Questions and TermsNotesHow many major plates do scientists estimate Earth has?How can a plate have both oceanic and continental crust?
