How mid-ocean ridges are formed
WebMid-ocean ridges. The global mid-ocean ridge system is the largest single volcanic feature on the Earth, encircling it like the seams of a baseball. Here the Earth’s crust is spreading, creating new ocean floor and literally renewing the surface of our planet. Older crust is recycled back into the mantle elsewhere on the globe, typically ... WebMar 4, 2024 · Explanation: Mid-ocean ridges are basically underwater mountains that are created with the help of lava convection (which causes the rising of plates) and the diverging (the pulling away) of tectonic plates. This is also how ocean floor spreading happens.

WebMar 4, 2024 · Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt. How do mid-ocean ridges increase the area of oceans? WebThe formation of the Mid-Atlantic Ridge took place in the following way. The tectonic plates on either side of the fault, started pulling away and separating from each other.
