At divergent boundaries hot mantle rock rises and what occurs?

At divergent boundaries, hot mantle rock rises and creates new oceanic crust as it cools and solidifies. This process leads to the formation of mid-ocean ridges, where tectonic plates move apart, allowing magma to surface. As the plates separate, earthquakes can occur, and volcanic activity is common, contributing to the geological features of the area. Over time, this continuous process shapes the ocean floor and influences the surrounding ecosystems.
