Plate Tectonics & Continental Drift Theory

What is the lithosphere asthenosphere? The crust The upper mantle The lower mantle A and B All of the above Fill in the blanks using the word options:mantle, crust, tectonic, lithosphere Tectonic plates are a block of lithosphere that consists of the crustand the rigid, outermost part of the mantle. Matching Terms Match the following terms and definitions by dragging a line between them. Continental Drift The theory that all continents were once one land mass that separated and drifted apart over time. Pangea the landmass that existed when all continents were joined Sea-floor spreading The process of new oceanic crust forming as magma rises toward the surface and solidifies Mid-ocean ridge A place where sea-floor spreading has occured Subduction when two tectonic plates collide, and one plate moves under the other and sinks into the mantle Subduction zones regions where subduction occurs theory of plate tectonics explains how large pieces of Earth’s outermost layer, called tectonic plates, move and change shape boundaries where tectonic plates meet convergent boundary boundary formed by the collision of two plates divergent boundary boundary between two tectonic plates that are moving away from each other transform boundary the boundary between two tectonic plates that are scraping past each other horizontally Sort the tectonic plate movement by its effect: Does it destroy crust, or does it create new crust? Destroys Crust subduction convergent boundary mountain ranges Creates Crust Sea-floor spreading mid-oceanic ridge divergent boundary Land formations Match which land formation is caused by which kind of tectonic plate movement. continental-continental convergent mountain ranges continental-oceanic convergent volcanoes oceanic-oceanic convergent islands oceanic-oceanic divergent mid-ocean ridges continental-continental divergent valleys transform fault lines Earth's Crustal Plates Name the seven continents. Are the continental plates made up of only continental crust? Explain. Which MAJOR plate is almost entirely covered with water? Name the plate that is located to the west of South America. If this plate is converging with western South America, what kind of formation is being created at that boundary? If the North American plate and the Eurasian plate are moving away from one another, what is being formed at that boundary? What type of boundary is formed between the Indian plate and the Eurasian plate? Name the major landform created there. Sort each item as either "Evidence for Continental Drift" OR "How Drift Occurs". Evidence Magnetic arrangement of iron minerals in bands along mid-ocean ridges. Similar fossils are found on different continents. Prehistoric climates on some continents are different than today's climate. How Drift Occurs Convection Currents Molten rock reaching the lithosphere moves horizontally hot material within the asthenosphere is forced upward Molten material closest to the crust's surface cools and becomes more dense, destroying some lithosphere with it.
