Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
New ocean crust is formed at ____
A
convergent boundaries
B
divergent boundaries
C
transform fault
D
None of the above
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Divergent boundaries–where new crust is generated as the plates pull away from each other. Convergent boundaries–where crust is destroyed as one plate dives under another. Transform boundaries–where crust is neither produced nor destroyed as the plates slide horizontally past each other.

Detailed explanation-3: -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-4: -Flexi Says: New oceanic lithosphere forms at divergent plate boundaries. As plates move away from each other the lithosphere thins and tears. At these divergent plate boundaries new oceanic lithosphere is created in the gaps from upwelling magma from the mantle.
