"We don't really know when plate tectonics as it looks today got started, but we do know that we have continental crust that was likely scraped off a down-going slab [a tectonic plate in a subduction zone] that is 3.8 billion years old," Van der Elst said. "We could guess that mea...

An investigation into plate tectonics in central Japan is conducted to make it clear what sort of motion is prevailing beneath the junction of Izu-Bonin and North Honshu arcs. At the beginning, an upper mantle model, consistent not only ... H Aoki - 《Earth Planets & Space》 被引量: 19...
The whole idea of plate tectonics is a more advanced version of an idea developed in the early 1900s called continental drift. During that time, ascientistnamed Alfred Wegener decided to investigate some obvious facts that he found curious about the way the Earth was put together. There were ...
Plate tectonics is the study of the motion of the plates in the Earth's crust. The Earth's tectonic plates are in constant motion...

The theory of plate tectonics is widely accepted by scientists and provides a robust framework with which to describe and predict the behavior of Earth's rigid outer shell – the lithosphere – in space and time. Expressions of plate tectonic interactions at the Earth's surface also provide ...
