Which of the following may be said about the geologic history of east and southeast North America?
A) Rifting occurred to separate North America from Rodinia around 600 Ma
B) Convergence and collisions occurred between about 500 Ma to 220 Ma, causing the Taconic, Acadian, and Alleghenian orogenies.
C) Rifting once again occurred around 200 Ma and created the Atlantic Ocean; North America underwent a cycle of rifting, collisions, and rifting.
D) All of these

The geologic history of east and southeast North America indeed includes all the mentioned events: the separation from Rodinia around 600 million years ago (Ma) due to rifting, a series of convergence and collisions from about 500 Ma to 220 Ma leading to the Taconic, Acadian, and Alleghenian orogenies, and another phase of rifting around 200 Ma that initiated the formation of the Atlantic Ocean. This sequence illustrates a cycle of rifting, collisions, and rifting again, shaping the continent's geological structure.
