Occurs when two tectonic plates move away from each other. Along these boundaries, lava spews from long fissures and geysers spurt superheated water. Frequent earthquakes strike along the rift. Beneath the rift, magma—molten rock—rises from the mantle. ...
One type of tectonic plate boundary — a boundary separates the large plates composing Earth's surface — is the convergent boundary. Tectonic plates are in constant, although extremely slow, movement. Their movements cause land to separate, islands to form, mountains to rise, water to cover lan...

resulting in a loosely spaced group of islands in the wide expanse of the ocean. The Japanese archipelago ranges from the tiny sub-tropical islands in the China Sea, of which the best known is Okinawa, up to the northerly cold island Hokkaido with its winter...
The Carboniferous and Permian volcanic rocks were deformed during the Hercynian and Indosinian tectonic movements, developing NW–SE and nearly E–W trending thrust faults. As shown in Fig. 4, affected by the tectonic stress field and faults, the trend of fractures was concentrated in the ...
How are tectonic plates movements classified? How are ocean trenches formed by tectonic plates? What is the asthenosphere made of? How are metamorphic and igneous rocks alike and different? How is the rock cycle related to plate tectonics? How does plate tectonics explain the formation of mountain...
