One of these mid-ocean ridges, the Mid-Atlantic ridge, is spreading apart making the Atlantic Ocean wider. As the two plates move the mantle melts, making magma and lava fill the void with newly ...
Web17 dec. 2024 · Mid-ocean ridges (e.g. Mid-Atlantic Ridge) are formed due to this kind of interaction. Here, the basaltic magma erupts and moves apart (seafloor spreading). On continents, East African Rift Valley is the most important geomorphological feature formed due to the divergence of African and Somali plates. WebThis theory was further supported by sea floor spreading, where new ocean crust was being continually created in zones in the middle of oceans, such as the mid Atlantic ridge which is moving the Eurasian plate and North American plate apart by 3cm/year.
