Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal. [1] It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone. [2] A transform fault is a special case of a strike-slip fault that also forms a plate boundary.
Strike-slip tectonics or wrench tectonics is a type of tectonics that is dominated by lateral (horizontal) movements within the Earth's crust (and lithosphere).Where a zone of strike-slip tectonics forms the boundary between two tectonic plates, this is known as a transform or conservative plate boundary.
In measuring the horizontal or vertical separation, the throw of the fault is the vertical component of the separation and the heave of the fault is the horizontal component, as in "Throw up and heave out". [11] The vector of slip can be qualitatively assessed by studying any drag folding of strata, which may be visible on either side of the ...
Scientists Found Ancient Tectonic Plates in the Middle of Continents—Where They Shouldn’t Be. Darren Orf. January 13, 2025 at 8:00 AM.
Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction. [citation needed]
The evolution of tectonophysics is closely linked to the history of the continental drift and plate tectonics hypotheses.The continental drift/ Airy-Heiskanen isostasy hypothesis had many flaws and scarce data.
