What does the divergence theory entail?

The divergence theory pertains to the movement of tectonic plates in Earth’s lithosphere. When it is stated that two plates are "pulling apart from each other," this is indicative of divergent plate boundaries. At these boundaries, tectonic plates move away from one another, which can lead to the formation of new oceanic crust as magma rises to the Earth's surface, cools, and solidifies. This process is evident at mid-ocean ridges, where such geological activity occurs.

This movement also contributes to phenomena such as earthquakes and volcanic activity, specifically in areas where the tectonic plates are generating new crust. The concept of divergence is foundational in understanding plate tectonics and the geological changes that shape our planet's surface.
