Final answer:
During the Late Proterozoic, North America was part of Laurentia, which later helped form Laurasia. This time also saw the Grenville Orogeny and the possible formation of the supercontinent Rodinia. The end of this era transitioned into the Cambrian, the start of the Paleozoic Era, marking significant changes in Earth's geological history.
Step-by-step explanation:
During the Late Proterozoic, specifically between 1 billion years ago (Ga) and 542 million years ago (Ma), the configuration of continents was notably different from today.
North America was part of a large continental block known as Laurentia, which also included Greenland. Laurentia maintained its integrity since the late Proterozoic, eventually colliding with Baltica to form Laurasia.
This era witnessed the Grenville Orogeny and the possible existence of the supercontinent Rodinia, where this orogenic event left its mark on continents such as North America, South America, Antarctica, Europe, and Africa.
The Neoproterozoic Era encompassed three periods, with the latest being the Ediacaran Period, leading up to the Cambrian period which marked the beginning of the Paleozoic Era.
The complete question is: North America in the late Proterozoic (1 Ga - 542 Ma). Elaborate!
