typically 2 things can happen:
1. the magma rises up and solidify s to become hard rock, so it is rebuilding the plate. This happens at on end of the plate, on the other side the plate is being melted away because its being forced into the magma.
2. volcano's form and earthquakes occur.
Long crack that forms as two tectonic plates move apart
When two plates move apart it forms a hole but new crust is formed.

When two lithosphere plates move apart a divergent boundary is formed. Hope this helps you. :D
Oceanic trenches are the gaps which form when the tectonic plates move apart. They are the very deepest parts of the ocean.
i believe its the rift valley
forms when two {crustal} lithosphere plates move apart.
It forms a hole but new crust is formed.
Plates move apart on divergent plate boundaries.
Rift Volcano forms when plates pull apart.
the plates move apart because of plate boundaries !:)
