art and magma rises to the surface, creating a new crust.
10. What role do they play in plate tectonics theory?
11. What happens when oceanic and continental crust collide

Answer 1

Oceanic ridges play a crucial role in plate tectonics theory, forming new crust through seafloor spreading. When oceanic and continental crust collide, the oceanic crust subducts beneath the continental crust.

Step-by-step explanation:

Oceanic Ridges in Plate Tectonics

Oceanic ridges play a crucial role in plate tectonics theory. They form at the boundaries between tectonic plates, where new crust is created through seafloor spreading. As magma rises to the surface, it cools and solidifies, forming new oceanic crust. This process helps drive the movement of plates and the continuous renewal of the Earth's surface.

Colliding Oceanic and Continental Crust

When oceanic and continental crust collide, the denser oceanic crust subducts beneath the less dense continental crust. This is because oceanic crust is thinner and denser than continental crust. Subduction zones are formed where the oceanic crust is forced beneath the overriding continental crust. This collision can result in the formation of mountain ranges and other tectonic features.
