Answer

Brief Explanations:

For Question 10, by the beginning of the Cretaceous period, the super - continents Laurasia and Gondwana were present. Pangaea had already started to break up into these two major landmasses. Rodinia existed much earlier in Earth's history. For Question 11, the principle of uniformitarianism states that the same geological processes that operate today have operated in the past.

Answer:

Question 10: A. Laurasia and Gondwana Question 11: C. Geological processes occurring today have always occurred in the past.
