GEOLOGY

Detailed explanation-1: -If two tectonic plates collide, they form a convergent plate boundary . Usually, one of the converging plates will move beneath the other, a process known as subduction.

Detailed explanation-2: -The most geologically active regions on Earth are where plates collide. When two oceanic plates converge, the cooler, denser one descends, or subducts, beneath the overriding plate and sinks into the mantle. When an oceanic plate meets a plate with a continent riding atop it, the oceanic plate is again subducted.

Detailed explanation-3: -In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.

Detailed explanation-4: -Oceanic-Oceanic Convergent Boundary 4. At a convergent boundary between two plates of oceanic lithosphere, the older, denser oceanic plate will always subduct, which will cause earthquakes and form volcanic isles.

Detailed explanation-5: -A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.
