How TECTONIC PLATES move WORKSHEET 3.1 Notes page 5—6 The _____ of the earth – the outer most layer of the earth, is constantly _____ . The Pacific Plate is the largest of the 7 major tectonic boundaries.With a size of 102,900,000 km 2, it more than doubles the size of the South American Plate.. A transform plate boundary occurs when two plates slide past each other. Why not a movie. Tags: Question 4 . Discover free flashcards, games, and test prep activities designed to help you learn about Tectonic Plate Movement and other concepts. This theory was developed in the 1960s. These tectonic plates rest upon the convecting mantle, which causes them to move. Earth › Tectonic plates › Volcano. Scientists have determined the direction that each plate is moving (Figure below). As the plates move, of course, so will the continents. Visualizations include simple animations, GIS-based animated maps, paleogeographic maps and globes, as well as numerous illustrations and photos. A study led by Harvard geologists has found evidence that the crust moved quickly over Earth’s surface in the deep past, a hallmark of modern plate tectonics. Where are Earth’s volcanoes? a river. a) mountain b) ocean basin c) fault d) volcano 4) What is the theory of plate tectonics? Transform boundaries are where two plates are moving laterally past each other. It is subdivided into rigid plates, known as tectonic or lithospheric plates. These move on a more fluid layer of the mantle, the asthenosphere. answer choices . Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. 1. Tags: Question 5 . Scientists explain this process through the theory of plate tectonics. Ocean trench. Theory of continental drift. Plate tectonics are odd because they often consist of oceanic and continental crust.For example, the Pacific Plate underlies the Pacific Ocean with the Hawaiian Islands positioned smack dab in the middle. It is subdivided into rigid plates known as tectonic or lithospheric plates. Teach your students about plate tectonics using these classroom resources. When one plate sinks on top of the other, sea pits form. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Although earthquakes can occur anywhere on earth, the majority of earthquakes worldwide occur at plate boundaries. Moving Ice Caps. This suggests that plate motion could have been a meaningful process in early Earth history. Just centimeters each year. These include constructive margins such as mid Atlantic ridge, two plates move away from each other. As the tectonic plates move, there are three different options for how they can interact with nearby plates: divergent, convergent, or transform boundaries. There are seven major plates which cover 94% of the Earth’s surface area: African plate; Antarctic plate The presence or absence of plate tectonics during this time is a topic of vigorous scientific debate. Start studying Using Figure 2, suggest how plate movements cause tectonic hazards in Iceland.. AKA: Lithospheric plate • The ~100-km-thick surface of the Earth; • Contains crust and part of the upper mantle; • It is rigid and brittle; • Fractures to produce earthquakes. plate tectonics 572 GIFs. Effect of Tectonic Plates. Color the fossils or mountains in the legend and color the symbols on each continent in the colors used in the legend. Every month the Earth is shaken by approximately 80,000 earthquakes. Plate tectonics is the theory that the surface of the earth is divided into a series of plates consisting of continental and oceanic crust. Molten rock or magma immediately rises to fill any possible gap and new oceanic crust. Earth’s tectonic plate boundaries are unusual because they can consist of continent and ocean crust. Tectonic plate movements. ? What are the tectonic plates? The scientific theory that explains the movement of the plates of the Earth's crust is the theory of plate tectonics. kilometers/month. The stresses cause folding, faulting and volcanic activity. Volcanic activity, earthquakes, mountain-building, and oceanic trench formation occur along these plate boundaries. Modified from USGS Graphics ? Tectonic plates move on average about 1 in (2.5 cm) per year—this is about as fast as a fingernail grows. Tectonic movements result in the deformation of the rocks making up the crust and are usually associated with a change in the chemical composition, phase state (mineral composition), and internal structure of the rocks subjected to deformation. The plate tectonics model states that the lithosphere is broken up into rigid slabs called tectonic plates or simply plates. Table of Contents show. Plate Motions. Convergent boundaries are areas where plates move toward each other and collide. Convergent boundaries are where two plates are colliding. By definition, the word "plate" in geologic terms means a large slab of solid rock. Tectonic plate interactions are classified into three basic types:. The 2006 U.S. Geological Survey map of tectonic plates show 21 of the major plates, as well as their movements and boundaries. SURVEY . Plate Tectonics 6 Making Pangaea Label each continent by name. The lithosphere, the outer part of the Earth, is made up of the crust and part of the upper mantle. a) plates move apart from each other b) plates collide (come together) c) plates slide past each other d) tectonic plate 3) What is the word for a large crack in Earth's surface? A divergent boundary occurs when two tectonic plates move away from each other. They are thicker than the ones that lie under oceans. Plate tectonics is a theory of geology.It explains movement of the Earth's lithosphere: this is the earth's crust and the upper part of the mantle.The lithosphere is divided into plates, some of which are very large and can be entire continents.. Heat from the mantle is the source of energy driving plate tectonics.
