24 Sea Floor Spreading Worksheet Answer
Sea-Floor Spreading Answer Key. This is a mid-ocean ridge. It is an underwater mountain range that forms when magma pushes up on the crust at a divergent boundary. Seafloor spreading is happening at B. Molten rock pushes up from the asthenosphere and pushes the plates apart at the mid-ocean ridge. This creates new ocean crust. The final proof of sea-floor spreading came from rock samples obtained by drilling into the ocean floor. Scientists found that the farther from a ridge the rocks were taken, the older they were. The ocean floor does not just keep spreading. Instead, it sinks beneath deep underwater canyons called deep-ocean trenches.
Modeling Seafloor Spreading Adapted from a lesson developed by San Lorenzo USD Teachers: Julie Ramirez, Veenu Soni, Marilyn Stewart, and Lawrence Yano (2012) Teacher Background The process of seafloor spreading created the seafloor of the oceans. For example, in the Atlantic
Wherever the sea floor is spreading, the edges move apart while the magma in the middle hardens. That means the rock in the center is the youngest. As the continents move apart, whole new oceans ... This Sea Floor Spreading Reading and Worksheet gives your students a 2 page reading which is easy to comprehend and full of information. Once students learn about the mid-ocean ridge, drifting continents, and how the Earth moves from the reading, they can put their knowledge to the test with a works Explain how seafloor spreading answers one or more of those questions. 226 228 229 The idea of seafloor spreading provides a mechanism to explain why continents move. Continents move with the ocean crust as it spreads away from mid-ocean ridges. Accept all reasonable responses. Sample answer: One of the questions was how the
Sea floor spreading worksheet answer. 7. How does seafloor spreading provide evidence of past plate motion? Answers will vary. Students should change the model so that magma is pushed out of the ridge, not pulled. Students should note that the pattern is the same on both sides of the ridge. Students should note that the ocean basin forms. It will be melted to make magma. The Process of Sea-Floor Spreading The new map of the ocean floor aroused the curiosity of many scien-tists. One geologist, Harry Hess, thought that the mid-ocean ridges and deep-ocean trenches might help to explain how the ocean floor was formed. In 1963, Hess published his hypothesis of sea-floor spreading. Seafloor Spreading - Atlantic Ocean. Express your average spreading rate answer for Problem 3 in terms of cm per year. Note- If the plates are moving apart symmetrically at the same rate (i.e., the color band widths are approximately equal), then 1/2 of this answer is the average rate at which the South American plate is moving west and the African plate is moving east.
