I want to know the answer to the following question:
What continent fractured off Gondwana in the direction of Laurentia?
All the background I'm provided with is that "Early in the Ordovician the continents Laurentia, Siberia and Baltica were still independent continents (since the break-up of the supercontinent Pannotia earlier), but Baltica began to move toward Laurentia later in the period, causing the Iapetus Ocean to shrink between them.". Is that enough to answer the question?
