C: This is important because we know that earthquakes happen regularly which can sometimes volcanic eruption when plates shift as magma is exposed thus claim 2

D: This is important because this shows us that if the plates only move 3 cm a year and the same fossil species is 4,000 miles away we can infer that these plates have been spreading apart for a very long amount of time thus claim 2
