The Wilson cycle theory is based upon the idea of an ongoing cycle of ocean closure, continental collision, and a formation of new ocean on the former suture zone.The Wilson Cycle can be described in six phases of tectonic plate motion: the separation of a continent (continental rift), formation of a young ocean at the seafloor, formation of ocean basins during continental drift, initiation of ...
The Wilson cycle describes the cyclicity in plate tectonics by forming supercontinents (Rodinia, Pangaea) and its breakup in hundreds of millions of years. It is named after the canadian geologist John Tuzo Wilson (1908-1993). Date: 1 November 2010, 01:00 (UTC) Source: File:Wilson-cycle hg.png: Author: Hannes Grobe 08:34, 21 January 2007 (UTC)
The Wilson cycle begins when previously stable continental crust comes under tension from a shift in mantle convection. Continental rifting takes place, which thins the crust and creates basins in which sediments accumulate. As the basins deepen, the ocean invades the rift zone, and as the continental crust rifts completely apart, shallow ...

The Wilson cycle of seabed expansion and contraction (associated with the Supercontinent cycle) bears his name, in recognition of his iconic observation that the present-day Atlantic Ocean appears along a former suture zone [8] and his development in a classic 1968 paper [9] of what was later named the "Wilson cycle" in 1975 by Kevin C. A ...

It is now in the decreasing phase of its cycle, and will reach its minimum around the year 11,800 CE. [15] Increased tilt increases the amplitude of the seasonal cycle in insolation, providing more solar radiation in each hemisphere's summer and less in winter. However, these effects are not uniform everywhere on the Earth's surface.
Wilson categorized species into evolutionary "stages", which today are commonly described in the outline by Ricklefs & Cox (1972). [3] However, with the advent of molecular techniques to construct time-calibrated phylogenetic relationships between species, the taxon cycle concept was further developed to include well-defined temporal scales [4] and combined with concepts from ecological ...
