Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
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.
Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere.This type of tectonics is found at divergent plate boundaries, in continental rifts, during and after a period of continental collision caused by the lateral spreading of the thickened crust formed, at releasing bends in strike-slip faults, in back-arc basins, and on the continental end of ...
For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi) African plate – Tectonic plate underlying Africa – 61,300,000 km 2 (23,700,000 sq mi) Antarctic plate – Major tectonic plate containing Antarctica and the surrounding ocean floor – 60,900,000 km 2 (23,500,000 sq mi)
Dynamic compression plate, metallic plate used in orthopedics to fix bone; Microtiter plate (or microplate or microwell plate), flat plate with multiple "wells" used as small test tubes; Orthopedic plate, internal fixation used in orthopaedic surgery; Petri dish or Petri plate, shallow dish on which biological cultures may be grown and/or viewed
When a large portion of dense materials was removed under the tectonic plate at this location, the remaining portion of the crust and lithosphere underwent a rapid uplift forming this mountain range. In geodynamics , delamination refers to the loss and sinking (foundering) of the portion of the lowermost lithosphere from the tectonic plate to ...
The Juan de Fuca plate itself has since fractured into three pieces, and the name is applied to the entire plate in some references, but in others only to the central portion. The three fragments are differentiated as such: the piece to the south is known as the Gorda plate and the piece to the north is known as the Explorer plate. The separate ...
Epiphyseal plate, a hyaline cartilage plate in the metaphysis at each end of a long bone; Lateral pterygoid plate of the sphenoid, a broad, thin and everted bone that forms the lateral part of a horseshoe like process that extends from the inferior aspect of the sphenoid bone; Nail plate, the hard and translucent portion of the nail
