How Seafloor spreading is occurring at the boundary between the?

Seafloor spreading occurs at divergent boundaries, primarily along mid-ocean ridges where tectonic plates are moving apart. As the plates separate, magma from the mantle rises to fill the gap, creating new oceanic crust. This process not only contributes to the growth of ocean basins but also drives plate tectonics, leading to geological phenomena such as earthquakes and volcanic activity along these boundaries. Over time, the continuous formation of new crust pushes older crust away from the ridge, resulting in the expansion of the ocean floor.
