The world's longest geologic feature is the Mid-Ocean Ridge system. The Mid-Ocean Ridge is an underwater continuous mountain range that snakes across the Earth’s oceans from the Arctic Ocean to the Atlantic, curving around Africa, Asia, and Australia, and then runs under the Pacific Ocean to the west coast of North America. It extends for about 65,000 kilometers (40,390 miles), making it the longest mountain range on the planet. The Mid-Ocean Ridge is a divergent tectonic plate boundary where plates are moving apart and new oceanic crust is being formed by upwelling magma from the mantle.
