Geo plate tectonics
WebIn geologic terms, a plate is a large, rigid slab of solid rock. The word tectonics comes from the Greek root "to build." Putting these two words together, we get the term plate tectonics, which refers to how the Earth's surface is built of plates. The theory of plate tectonics states that the Earth's outermost layer is fragmented into a dozen or more large and … WebPlate tectonics is the hypothesis that Earth’s external shell is separated into a few plates that float over the mantle, the rough inward layer over the core. The plates demonstration like a hard and unbending shell contrasted with Earth’s mantle. This solid outer layer is known as the lithosphere, which is 100 km (60 miles) thick.

WebWhen tectonic plates collide, the heaviest plate moves beneath the lighter one. This interaction creates a subduction zone and destruction of crustal rocks which eventually triggers earthquakes. In the same zone and during the subduction process, magma is released onto the surface through eruption creating volcanoes. chmm pass rateWebEarth’s lithosphere, or outermost shell, is broken up into large pieces called tectonic plates.
