The mid-ocean ridge is a volcanic feature caused by the spreading apart of oceanic plates as part of plate tectonics, and is initially formed as a result of changes in the convection currents which seek the least resistant point to the surface. The sea floor at the ridges are uplifted by rising magma. The rising magma is part of a process of heat transfer from the interior of the Earth to the surface known as a convection current. As the rising magma cools, it forms new crust which becomes part of the ridge.
What else can I help you with?
When was Cortical Tectonics created?
Cortical Tectonics was created in 2007-06.
What is the process by which plate tectonics produces new oceanic lithosphere at ocean ridges called?
Seafloor Spreading.
What occurs when two tectonics plates move away from each other?
mid-ocean ridges and volcanoes
What are some landforms that support the plate tectonics theory?
Examples of landforms that support the plate tectonics theory include mid-ocean ridges, deep-sea trenches, and volcanic arcs. These features provide evidence of seafloor spreading, subduction zones, and volcanic activity at plate boundaries, which are key aspects of the theory.
Why oceanic crust younger than the continental crust?
Oceanic crust is constantly created and recycled due to place tectonics. Oceanic crust is created by spreading ridges in the ocean floor and the oceanic plates subside under continental plates thus forcing it back down into the magma as the plate grows. Searching Oceanic Plate Tectonics on google will provide images that made this easier to understand.

What are the crustal features of the land that are formed by plate tectonics?
Crustal features created by plate tectonics include mountains (e.g. Himalayas), trenches (e.g. Mariana trench), volcanoes (see the Ring of Fire), ocean ridges (Mid-Atlantic Ridge) and rift zones (regions lateral to a volcano that lava flows from).
Which theory explains the processes that shape the Earths surface into mountains deep-sea trenches and oceanic ridges?
plate tectonics
How is crust created at the oceanic ridge?
Mid-ocean ridges are a line of volcanic mountains under the oceans between the continents. As the oceanic plates are being pulled apart by the processes of plate tectonics, magma is formed from decompression melting in the mantle, and rises upward to fill in the gap that is created. Because this material solidifies and is still hot, it is buoyant and rises higher than the surrounding seafloor, creating the ridges. As it is pulled away from the spreading point by plate tectonics, it gradually cools, making it less buoyant; it gradually drops in elevation.

How do plate tectonics cause the continents to grow?
Plate tectonics cause the continents to grow through a process called seafloor spreading. This occurs at mid-ocean ridges, where new oceanic crust forms as tectonic plates move apart. As more crust is added at these ridges, it pushes the existing continents away from each other, causing them to grow in size over millions of years.
How do mid ocean ridges support the idea of continental drift and the theory of plate tectonics?
Mid-ocean ridges are underwater mountain ranges where new oceanic crust is formed through volcanic activity. As the magma rises, it creates new crust that pushes the existing plates apart, providing evidence for seafloor spreading and supporting the theory of plate tectonics. The movement of these plates at mid-ocean ridges helps explain how continents have drifted and repositioned over geological time scales.
Where is new sea floor created?
the ridges
Places where new seafloor is being created?
New seafloor is created at mid-ocean ridges, where tectonic plates are moving apart. As the plates separate, magma from the mantle rises to the surface, solidifies, and forms new crust. This process is known as seafloor spreading.
