Supercontinent cycle - Wikipedia
One complete supercontinent cycle is said to take 300 to 500 million years. Continental collision makes fewer and larger continents while rifting makes more and smaller continents. The most recent supercontinent, Pangaea, formed about 300 …
The supercontinent cycle - Nature Reviews Earth & Environment
2021年4月20日 · The supercontinent cycle is an outcome of plate tectonics as a self-organizing system, where a supercontinent is both an effect and a cause of mantle convection, thus creating a...
Supercontinent | Definition, Cycle, & Facts | Britannica
2024年11月15日 · Three models have been developed to explain the supercontinent cycle, each of which depends upon the location of subduction zones (regions in which oceanic crust at the surface is conveyed back into the mantle). In each model, a supercontinent begins by being surrounded by an enormous exterior ocean, and rifting creates a new interior ocean ...
In this Review, we discuss how the emergence of supercontinents provides a minimum age for the onset of the modern global plate tectonic network, whereas Archaean supercratons might reflect an...
How Does the Supercontinent Cycle Work? - Earth How
The supercontinent cycle is a long-term geological process that involves the repeated formation and breakup of supercontinents over millions to billions of years. This pattern can be seen through the fossil record, and it is characterized by a large number of supercontinents followed by a long period with many smaller continents.
What supercontinents have existed throughout Earth's history?
2024年1月13日 · Scientists believe that supercontinents form on a cycle every several hundred million years or so, and we should expect another one in around 250 million years.

2021年3月15日 · In a prototypal form, a cyclic pattern of continental assembly and 65 breakup likely extends back to ~3 billion years ago, albeit on the smaller scale of Archaean 66 supercratons which, unlike...
Supercontinent - Wikipedia
A supercontinent cycle is the break-up of one supercontinent and the development of another, which takes place on a global scale. [4] Supercontinent cycles are not the same as the Wilson cycle, which is the opening and closing of an individual oceanic basin. The Wilson cycle rarely synchronizes with the timing of a supercontinent cycle. [1]
The supercontinent cycle and Earth's long-term climate
2022年6月28日 · The supercontinent cycle, by which Earth history is viewed as having been punctuated by the episodic assembly and breakup of supercontinents, has, through its management of plate motion, planetary geography, sea level, and mantle circulation, profoundly influenced Earth's long-term climatic history.
The supercontinent cycle: A retrospective essay - ScienceDirect
2014年1月1日 · Earth history has been punctuated by the assembly and breakup of supercontinents. The influence of the supercontinent cycle on Earth’s geologic record is profound. Recognition of the cycle is a major milestone in the development of Earth Science.
