WebOn the afternoon of March 11, 2011, a large earthquake struck off the northeastern coast of Japan. This event, which would prove to be deadly, was caused by a specific type of plate movement: subduction. Subduction occurs when one tectonic plate—the one that is older and denser—sinks or is pulled under another tectonic plate. WebContinents fit together along the edges of their continental shelves. Mid-ocean ridges and deep-sea trenches develop at the boundaries of the moving plates. Volcanic islands and seamounts develop where a plate moves over a stationary hotspot. The new earthquake data revealed three startling observations.

What Causes Continental Drift? - (Top Reasons!)

WebWherever continents are bordered by deep-sea trench systems, as in the Pacific Ocean, the ocean floor is plunged downward, underthrusting the continents and ultimately reentering and dissolving in Earth ’s mantle, from which it had originated.

He said that the continents floated atop the mantle-a heavier, denser layer of rocks deep within the earth. Wegener predicted … dance music from the 50s

What is Plate Tectonics? Plate Tectonics Live Science

WebIf the plates move a significant distance very suddenly, this causes an earthquake. There are no volcanoes at this type of boundary as melting of the rock does not occur. WebConverging currents drive plates into each other. Diverging currents pull them apart. This is mostly true. Hot mantle rock rises from the core and moves along under the crust until it grows cool and heavy and sinks back down again. But the plates aren't just passively riding these currents around like a bunch of suitcases at the baggage claim. bird tune download

The idea of continental drift has been subsumed into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1…
