"WebIntroduction: Plate tectonics is the theory that Earth’s rigid outer layer, known as the lithosphere overlies the plastic-like layer of the mantle called the asthenosphere. The lithosphere is broken up into about a dozen large “plates” and several small ones. These plates move relative to each other, typically at rates of 5 to 10 cm (2 to 4 inches) per … " - Lithosphere formation

WebThe formation of rift basins and strain localization reflects rift maturity. At the onset of rifting, the upper part of the lithosphere starts to extend on a series of initially unconnected normal faults, leading to the development of isolated basins. [8]

Web1 okt. 2024 · The concept of lithosphere has evolved considerably since it was introduced by Barrell [ 4] to describe the strong outer shell or lid of the Earth. Earth's lithosphere has three useful definitions: thermal, chemical and rheological/mechanical [ 5 ]. WebThe lithosphere is defined as the rigid outermost shell of Earth, comprising continental and oceanic crust and the uppermost mantle. The Moho-discontinuity is an intralithospheric interface. The lithosphere is a strong, elastic layer overlying the weak, ductile asthenosphere with a more or less gradual transition.
