What is the topographic feature that marks where the seabed is being subducted into the Earth’s Mantle?
Ans) The volcanoes known as "Continental arc " are formed.When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate as a result magma rises and erupts, creating these volcanoes.
