a build up of pressure
At mid-ocean ridges, tectonic plates are moving apart from each other due to seafloor spreading. Magma rises up from the mantle to fill the gap between the diverging plates, creating new oceanic crust. This process pushes the existing crust away from the ridge and helps drive the movement of the tectonic plates.
When tectonic plates pull apart, they create gaps between them through which magma from the mantle can rise. As the magma cools and solidifies, new crust is formed at these mid-ocean ridges. This process is known as seafloor spreading.
A divergent boundary forms when tectonic plates pull apart. As the plates move away from each other, magma rises up to create new crust, resulting in features like mid-ocean ridges or rift valleys on land.
I'm guessing you're talking about the tectonic plates? Divergence.
Tectonic plates can split apart at their boundaries, known as divergent boundaries, where new crust is formed. However, tectonic plates do not split in half as a whole; instead, they interact along their edges at various types of plate boundaries.

Tectonic plates interact at plate boundariesThey move apart at divergent boundaries
Tectonic plates, if it is the plates you are talking about, move because of Earth's interior. Recall that inside Earth is flowing lava that rises to the surface. That lava pushes the plates nearest it so it can make place for itself.
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.
Convergent Boundary
Converging plates come together. They converge together. Diverging plates come apart.
Seafloor spreading happens when two tectonic plates move apart. Magma rises up from the mantle through the gap, creating new oceanic crust. As the plates continue to move apart, the new crust pushes the older crust away, causing the seafloor to spread.
tectonic movement can cause tectonic plates to collide, drift apart, or slide across one another
Yes. Tectonic plates are extremely strong and catastrophic in some cases.
