What are the three main components of the Wilson cycle for plate tectonics?

Abstract. By 1968, J. Tuzo Wilson had identified three basic elements of geodynamics: plate tectonics, mantle plumes of deep origin, and the Wilson Cycle of ocean opening and closing, which provides evidence of plate tectonic behavior in times before quantifiable plate rotations.

What are the 6 stages of the Wilson cycle?

A Wilson cycle consists of six stages: embryonic, juvenile, mature, declining, terminal, and suturing.

What is the Wilson cycle in geology?

The Wilson Cycle is a model that describes the opening and closing of ocean basins and the subduction and divergence of tectonic plates during the assembly and disassembly of supercontinents. A classic example of the Wilson Cycle is the opening and closing of the Atlantic Ocean.

What is the motion of a rifting stage of the Wilson cycle?

In plate tectonic theory earth history, at its simplest, is one of plates rifting into pieces diverging apart and new ocean basins being born, followed by motion reversal, convergence back together, plate collision, and mountain building. This cycle of opening and closing ocean basins is the Wilson Cycle.

Where do the six stages of Wilson cycle occur?

As outlined in Table 1 and Figure 2, the six-stage cycle for opening and closing of ocean basins (only later termed the Wilson Cycle) comprises: (1) the dispersal (or rifting) of a continent (Embryonic Ocean); (2) the formation of a young new ocean by seafloor spreading (Young/Juvenile Ocean); (3) the formation of …

What is formed right after the rifting of a supercontinent?

A supercontinent cycle consists of rifting and break up of one supercontinent, followed by a stage of reassembly in which dispersed cratons collide to form a new supercontinent, with most or all fragments in different configurations, compared to the older supercontinent.

Will the Red Sea become an ocean?

In Djibouti at the gateway of the Red Sea an oceanographic marvel is occurring – a new ocean is being formed. This ocean is being created by the tectonic plates of Africa and Arabia being torn apart. All oceans are formed in this way, but this is one of the rare places where this process can be witnessed first hand.

Which would be an example of the final stage of the Wilson cycle?

An example of stage E is the Mediterranean Sea. Suturing (Continental Collision) Stage F: This is the final stage, before the mountain chain eventually will erode down to a peneplain (that’s when the mountains have eroded all the way down to the sea-level).

How do rifting and accretion change the shape of continents?

Identify how rifting and accretion change the shapes of continents. This changes the shapes of continents because different parts of the continents converge and diverge at different rates. So the Northern part of a continent could be spreading apart faster than the southern. Describe the supercontinent cycle.

Is Africa splitting apart?

The African continent is slowly separating into several large and small tectonic blocks along the diverging East African Rift System, continuing to Madagascar – the long island just off the coast of Southeast Africa – that itself will also break apart into smaller islands.
