Plate Tectonics Guided Notes 2024 Geology Vocab Cards w/ Definitions Presentation Link 1) Write down some details about plate tectonics- 2) Which direction is the North America plate moving? Convergent boundraires 3) Which direction is the South America plate moving? Divergent and convergent boundaries 4) Which direction is the Pacific plate moving? How did this move in the past? Mostly convergent 5) Which direction is the Eurasian plate moving? Convergent 6) Which direction is the Australian plate moving? Convert and divergent 7) Why are plates moving in different directions? The heat under the mnatle 8) Alfred Wegener- Who is he and why was he important? He came up with the theory of continental dirft; we would not have a explanation of how the continents moved if he never came up with this theory then we would never have explanation for a lot of things. 9) Evidence of Continental Drift- What are 4 lines of evidence? Continents fit like a puzzle piece Matching fossil evidence Rock type and structures Ancient climate data 10) Pangaea- 300-200 mya. Why was it all stuck together? Plate tectonics 11) Mesosaurus- What is it? What does it suggest if found in 2 different locations across an ocean? It was found in africa nad south america, it a dinoraourse, this suggest that the land was once near/same location. 12) Mountain Ranges- Which ones were connected? Himalaya mountains 13) Circle or draw an arrow to an example of a transform, divergent and convergent area on this map. 14) Four evidences of Plate Tectonics a) Paleomagnetism the magnetic field changes and that everything is moving b) Earthquake Patterns tends to follow the divergent plates and deeper earthquakes follow around the ocean to land boundaries c) Ocean Drilling These areas where new crust forms and moves apart are called spreading centers. Since new ocean crust is forming, the old crust has to be disappearing somewhere, and turned out that the old crust was sinking back into the mantle d) Hot Spots a spot that is uncommonly hot in the mantle(a hole) and make a string of volcanic islands. 15) Lithosphere- What is it? Why is the ocean so comparably young next to the continental crust? Because of pelemoagenism 16) Asthenosphere- What is it a part of? The earth's crust 17) Earth’s Interior- Describe elements in each layer 18) Oceanic vs Continental Crust ocean crust in made of ocean floor material and continental is made of land masses. 19) Mantle- Peridotite- 20) Causes of Plate Motion slab pull and ridge push. 21) Three types of heat transfer convection, conduction, radiation 22) Divergent Plate Boundary (2 types)- a) Mid Ocean Ridge underwater volcanos b) Continental Rift Valley a lowland region that forms where Earth's tectonic plates move apart, or rift 23) Convergent Plate Boundary (3 types)- a) Continent to continent makes mountain ranges. same density. b) Continent to Ocean when plates make a convergent boundary on a countain and an ocean c) Ocean to Ocean when plates make a convergent boundary over an ocean. d) Transform Boundary where two tectonic plates grind up against each other and move sideways. 24) Magnetic Reversals how the magnet and the earth crust and how it’s changed over the years. 25) Recap
