because of erosion the ocean are basically taking pieces and pieces of land so each continents would fit perfectly if there wasn't any erosion happeing
The continents do not fit perfectly together because they have changed shape and position due to geological processes like continental drift and erosion. The breakup of the supercontinent Pangaea around 200 million years ago further altered coastlines and created new geographical features. Measurement of continental boundaries can also reveal a more complementary fit than what is visible on a map.
