Textbook Reading Assignment In your textbook, read the chapter entitled “Plate Tectonics” , pages 107-121. 2. Matching As you read through the text, fill in the table below by matching the vocabulary word with its correct definition. The first one is completed as an example. Vocabulary Word List: Sedimentary rocks Crust Continental rocks Relative dating Ocean floor Plate tectonics Radiometric dating Lithosphere Word Definition 1. Ocean Floor The outermost layer of the geosphere beneath the sea or ocean 2. Continental rocks Granite, sedimentary, and metamorphic rocks that form land above sea level 3. Lithosphere The solid, rocky shell of the geosphere 4. Relative dating A theory explaining the movement of the lithosphere over the fluid asthenosphere 5. Plate tectonics The rigid portion of Earth consisting of the crust and part of the mantle 6. Radiometric dating A technique using radioisotopes to determine the age of samples 7. Crust These are formed when deposits are pressed together over time 8. Sedimentary rocks A technique of using positions of rocks within geologic formations to determine relative ages of samples

To access this video… 1) Log into your SCUSD Clever Page. 2) Click on your digital textbook app for “Stemscopes”. 3) When you open up Stemscopes, you will be able to see the link to the Content Connection Video you are supposed to watch. Plate Tectonics - After watching the video, answer the following questions below: 1. What is explained by the theory of plate tectonics? major landforms are created as a result of Earth's subterranean movements 2. Describe the mantle. mantle is the mostly solid bulk of Earth's interior. The mantle lies between Earth's dense 3. List the nine major plates. Pacific Plate: North American Plate: Eurasian Plate: African Plate: Antarctic Plate: Indo-Australian Plate: South American Plate: 4. Compare convergent, divergent, and transform plate boundaries. Divergent - tectonic plates move apart. Transform - tectonic plates slide past each other. 5. Give evidence that supports the idea that the continents were once connected. fossil record

62/100 SLO 01/24/2024 Signed // Sha±²³n Oet´±µ¶r // Introduction to Plate Tectonics- For the 2nd video for this chapter, I would like you to watch an SCUSD approved Youtube video entitled “Introduction to Plate Tectonics” . (The video is less than 4 minutes long, and was created by Mr. Frank Gregorio.) You can use the following link to view the video. https://www.youtube.com/watch?v=fzhPmemffII&ab_channel=FrankGregorio Please watch this video twice! On your first viewing, simply enjoy the video’s incredible graphics while marveling at our dynamic planet Earth. On your second viewing, please answer the following questions below. 1. What are the two causes for why the interior of the Earth is hot? (over 25,000 ℉ !) 2. After cracking, into how many separate pieces (plates) has the Earth’s crust been divided? 3. What is the driving force that causes the plates of the Earth's crust to move apart in some places and collide in other places? 4. What is it that forms where continental tectonic plates collide? 5. Do volcanoes explode where plates collide or where plates are moving apart?
