Why Is The Asthenosphere So Important To Plate Tectonics? Convection currents generated within the asthenosphere push magma upward through volcanic vents and spreading centres to create new crust. … According to the theory of plate tectonics, the asthenosphere is the repository for older and denser parts of the lithosphere that are dragged downward in subduction
What Part Of The Upper Mantle Can Flow? The asthenosphere is solid upper mantle material that is so hot that it behaves plastically and can flow. Which word best describes the hot weak inner part of the upper mantle which can flow lithosphere asthenosphere core crust? The asthenosphere is a part of the upper mantle
How Do Plate Tectonics Create Landforms? Volcanoes and ridges are landforms that are created by the movement of tectonic plates. Some volcanoes are formed when the plates pull apart under the ocean. A crack in Earth’s crust forms. Magma rises through the crack, forming ridges. What role did plate tectonics play in creating landforms on
What Are Some Examples Of Plate Tectonics In Nature? Volcanic eruptions. As with earthquakes, volcanic activity is linked to plate-tectonic processes. Most of the world’s active above-sea volcanoes are located near convergent plate boundaries where subduction is occurring, particularly around the Pacific basin. What is an example of a natural hazard related to plate tectonics?
