Little is known about the paleogeography before the formation of Rodinia. Paleomagnetic and geologic data are only definite enough to form reconstructions from the breakup of Rodinia [17] onwards. Rodinia is considered to have formed between 1.3 and 1.23 Ga and broke up again before 750 Ma. [18] Rodinia was surrounded by the superocean Mirovia.
Pangaea's supercontinent cycle is a good example of the efficiency of using the presence or lack of these entities to record the development, tenure, and break-up of supercontinents. There is a sharp decrease in passive margins between 500 and 350 Ma during the timing of Pangaea's assembly.
The continents that had drifted away from Rodinia drifted together again during the Paleozoic: Gondwana, Euramerica, and Siberia/Angara collided to form the supercontinent of Pangea during the Devonian and Carboniferous periods, some 350 million years ago. Pangea was a short-lived supercontinent; it began to break apart again in the early ...
The supercontinent Rodinia began to break up 870–845 Ma probably as a consequence of a superplume caused by mantle slab avalanches along the margins of the supercontinent. In a second episode c. 750 Ma the western half of Rodinia started to rift apart: western Kalahari and South China broke away from the western margins of Laurentia ; and by ...

RTVC Sistema de Medios Públicos (abbreviation of Radio Televisión Nacional de Colombia, known by its acronym RTVC) is a public radio and television entity of Colombia, created by Decree 3525 of October 28, 2004, by dissolving Inravisión and its public production company Audiovisuales, under the government of President Álvaro Uribe Vélez.
En Vivo (known as Nuevos Días TV from 1995 until the end of 1997) was a Colombian programadora that operated between 1995 and 2001. Its main productions were the morning program En vivo (1995–96), the interview program by the same title (1996–97), and the newscasts En vivo 9:30 (evening) and En vivo 6:30 (morning) that aired on Canal A from 1998-2001.
Rodinia lasted for 250 mya and then began to come apart between 850 and 800 mya. The continent began to break part at a single point but then fractured and ripped open in three different directions. Two of the three rifts that were created were successful and the third failed.
