Final answer:
The ancient landslide associated with a volcano on Moloka'i created what may be the world's tallest sea cliffs on that island. Moloka'i's sea cliffs are the result of a massive landslide, which is part of the larger geological hot spot activity that formed the Hawaiian islands.
Step-by-step explanation:
The ancient landslide that resulted from the collapse of a flank of the ancient volcano, sometimes called Wailau, is associated with Moloka'i. This massive landslide distributed debris across the ocean floor and resulted in the formation of what may be the world's tallest sea cliffs on the island. While there are several notable volcanic formations within the Hawaiian island chain, it's specifically Moloka'i that is known for this geological phenomenon. The volcanic activity that created the Hawaiian islands, including these dramatic sea cliffs, is the result of the movement of the Pacific Plate over a volcanic hot spot. Over time, this geological process has formed a series of islands, with each showing unique features derived from volcanic activity, like the impressive Mauna Kea which is considered a premier site for astronomy due to its high altitude and the visibility it provides.
