WebTheory and Evidence of Seafloor Spreading. Seafloor spreading is a geologic process where there is a gradual addition of new oceanic crust in the ocean floor through a volcanic activity while moving the older rocks away from the mid-oceanic ridge. The mid-ocean ridge is where the seafloor spreading occurs, in which tectonic plates —large ...

How was the Mid-Atlantic Ridge Formed? - Science Struck

The deep-sea marine animals residing in the Mid-Atlantic Ridge region, are not dependent on sunlight/photosynthesis for their survival. Instead, they get their energy from microbes, that oxidize chemical compounds being spewed from hydrothermal volcanic vents through chemosynthesis.
