Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where does seafloor spreading occur?
A
at convergent plates
B
on seamounts
C
near the ocean surface
D
at divergent plates
Explanation: 

Detailed explanation-1: -Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.

Detailed explanation-2: -Sea floor spreading takes place at the divergent boundary between two plates or mid-ocean ridges.

Detailed explanation-3: -The divergent boundaries are the areas where plates are moving apart from one another. Where plates move apart, new crustal material is formed from molten magma from below the Earth’s surface. Because of this, the youngest sea floor can be found along divergent boundaries, such as the Mid-Atlantic Ocean Ridge.

Detailed explanation-4: -Areas of seafloor spreading are along a divergent plate boundary because the plates are being pushed apart by the rising magma.

Detailed explanation-5: -Seafloor spreading is when the sea floor spreads apart. This occurs at Divergent Boundaries. At which type of boundary is seafloor destroyed? The seafloor is destroyed at a COnvergent Boundary.
