.................................Earth's Largest Geologic Feature


The Arctic Ridge forms the northernmost part of Earth’s Mid-Ocean Ridge. The Ridge is a chain of undersea mountains in every ocean that circles the earth like the seam of a baseball for about 60,000 kilometers (40,000 miles).  It is the place where Earth’s crust is born as two tectonic plates move apart in seafloor spreading.

The mid-ocean ridge (shown in red on left) winds its way between the continents much like the seam on a baseball (shown in cartoon on right). (Image on left courtesy of USGS)
