Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Mid-ocean ridges are an example of which type of plate boundary?
A
Convergent
B
Divergent
C
Transform
D
Sea-floor spreading
Explanation: 

Detailed explanation-1: -The mid-ocean ridge system is an example of a divergent plate boundary. For example, the Mid-Atlantic Ridge is formed in the Atlantic ocean because of the divergence of the North American plate from the Eurasian Plate and the South American plate from the African plate.

Detailed explanation-2: -Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.

Detailed explanation-3: -Mid-oceanic ridges are plate boundaries where new oceanic crust is created. The mid-ocean ridge system is an example of a divergent (rather than a convergent or transform) plate boundary.

Detailed explanation-4: -Divergent plate boundaries in the ocean create mid-ocean ridges. This is where new seafloor is created by upwelling magma. Divergent plate boundaries rift a continent apart. Eventually a new ocean will form between the two continents.

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.
