What Is The Asthenosphere Of The Earth? The asthenosphere is the denser, weaker layer beneath the lithospheric mantle. It lies between about 100 kilometers (62 miles) and 410 kilometers (255 miles) beneath Earth’s surface. The temperature and pressure of the asthenosphere are so high that rocks soften and partly melt, becoming semi-molten. What is the
How Does The Theory Of Plate Tectonics Explain Earthquakes? Earthquakes occur along fault lines, cracks in Earth’s crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they
Which Is True According To The Plate Tectonic Theory? Which statement is TRUE according to plate tectonic theory? Plates of rigid lithosphere lie on top of the weak asthenosphere. Seafloor spreading occurs at this type of plate boundary. According to plate tectonic theory, convergence between two plates of ocean lithosphere created these volcanoes. Which is
What Is The Name Of The Theory That Explains Why Mountain Ranges In Africa And South America Line Up Pangaea Theory Landmass Theory Continental Drift Theory Plate Movement Theory Brainly Com? The theory of plate tectonics explains most of the features of Earth’s surface. It explains why earthquakes, volcanoes and mountain ranges are where they
What Is The Difference Between The Continental Drift Hypothesis And The Tectonic Plate Theory? The main difference between plate tectonics and continental drift is that plate tectonics describes the features and movement of Earth’s surface in the present and in the past whereas continental drift describes the drifting of Earth’s continents on the ocean bed.
What Accurately Describes Plate Tectonics? The theory of plate tectonics states that the Earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet. Which statement explains why
How Do Plate Tectonics Regulate Carbon Cycle? Plate tectonics plays a crucial role in driving the long-term carbon cycle because it is responsible for CO2 degassing at ridges and arcs, the return of CO2 to the mantle through subduction, and supplying fresh, weatherable rock to the surface via uplift and orogeny. How might plate tectonics
Can Plate Tectonics Be Proven? Can plate tectonics be proven? Modern continents hold clues to their distant past. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. How do we know the theory of plate tectonics is true?
