Rift zones are narrow areas along the oceanic trenches where hot solid mantle rocks rise upward to replace the material that has shifted horizontally.

Question

Rift zones are areas where the Earth's crust and lithosphere are being pulled apart, not along oceanic trenches but typically at mid-ocean ridges or continental rift zones. Here, hot, solid mantle rocks rise upward due to decompression melting, but this process is associated with divergent plate boundaries, not the convergent boundaries where oceanic trenches are found.
