I'm guessing you're talking about the tectonic plates? Divergence.
convergant plate boundries
When plates move apart from each other, it's known as divergent plate boundary. This process usually happens along mid-ocean ridges where new crust is formed as magma rises and solidifies.
When plates move apart from each other in opposite directions, it is called divergent boundary or a constructive boundary. This process typically happens at mid-ocean ridges where new oceanic crust is formed as magma rises up and solidifies.
When two tectonic plates spread apart from each other, it is called a divergent boundary. This process often leads to the formation of new oceanic crust as magma rises to the surface, creating mid-ocean ridges. Divergent boundaries can also occur on land, resulting in rift valleys.
Divergent plate boundaries form once two plates begin to pull apart from each other.
The movement you are referring to is called seafloor spreading. It occurs at mid-ocean ridges, where two tectonic plates move apart from each other, causing magma to rise and solidify, creating new oceanic crust.
The theory that explains how continents moved apart is called plate tectonics. It proposes that the Earth's lithosphere is divided into several large plates that move and interact with each other, causing phenomena like continental drift, earthquakes, and volcanic activity.
Scientists believe that plates are moved by the process of mantle convection, where heat from the Earth's core causes the mantle to circulate and create movement in the tectonic plates above. The plates can slide past each other, collide, or move apart due to the forces generated by this convection in the mantle.
probably divergent,
When two plates move apart from each other, it creates a divergent boundary. Magma from the mantle rises to fill the gap, solidifies, and forms new crust. This process is called seafloor spreading and is responsible for the formation of mid-ocean ridges.
The action of continents drifting apart from each other is called, "Continental Drift". It is no longer a theory, as it has been proven to be so. Of course, as certain continents move apart from each other, they also are moving closer to other continents.

At a mid-ocean ridge, tectonic plates move apart from each other due to seafloor spreading. Magma rises up from the mantle, solidifies at the ridge, and forms new oceanic crust. This process pushes the plates away from each other, causing them to move in opposite directions.
Trenches form where plates are moving towards each other in a convergent plate boundary, not where they are moving apart. At divergent boundaries, such as mid-ocean ridges, plates are moving apart, creating new crust.
The theory that explains how the continents have moved apart is called plate tectonics. This theory suggests that the Earth's outer shell is divided into several plates that move and interact with each other, causing continents to drift over long periods of time. This movement is driven by processes such as seafloor spreading and subduction.
