Rocks formed by the rapid hardening of molten material.
Scientists observed a series of underwater mountains, deep valleys, and hydrothermal vents releasing mineral-rich fluids. They also found unique ecosystems thriving in the extreme conditions near the mid ocean ridge.

In the 1960s, scientists discovered a central rift valley along the mid-ocean ridge system. This valley is an underwater depression that forms at the crest of a ridge where tectonic plates are moving apart. Here, new oceanic crust is created through volcanic activity, providing important insights into the process of seafloor spreading and plate tectonics.
Scientists discovered that rocks farther away from the mid-ocean ridge were older through radiometric dating of the rocks. By analyzing the age of the minerals within the rocks, researchers found that the rocks closest to the ridge were younger, while those farther away were older, supporting the theory of seafloor spreading.

Mid-Ocean Ridge
Scientists have observed the beginnings of a new ocean basin in the Afar desert in the northeast region of Ethiopia. New ocean basins are still being formed at the Mid-Ocean Ridge in the Atlantic Ocean. This process involves the formation of new basalt. The process of subduction counter-balances the aforementioned, destroying older parts of the ocean floor. This is formally known as sea-floor spreading.
They measure how far away the rock is from the mid-ocean ridge. The farther, the older.
Scientists discovered that rocks farther away from the mid-ocean ridge were older than those closer to it through radiometric dating of the rocks. By analyzing the age of the rocks using isotopes with known half-lives, they were able to determine that the rocks get progressively older as you move away from the ridge due to the process of seafloor spreading.
