The Arctic Ocean is believed to have formed during the Late Mesozoic Era, around 200 million years ago, as a result of plate tectonic activity. It developed as the supercontinent Pangaea began to break apart, leading to the opening of the ocean basin. The ocean's current boundaries were shaped by subsequent geological processes, including the movement of the North American, Eurasian, and other surrounding tectonic plates. Over millions of years, sedimentation and glacial activity further influenced its structure and characteristics.
