what geologic feature is formed between the diverging oceanic plates

The geologic feature formed between diverging oceanic plates is a mid-ocean ridge. It’s an underwater mountain chain created where new oceanic crust rises and solidifies as the plates pull apart.

Quick Scoop

At a divergent boundary in the ocean, magma moves up from below and forms new seafloor. This process builds the ridge, and a rift valley may run along its center.

In simple terms

• Diverging oceanic plates = plates moving away from each other.
• New crust forms in the gap.
• Mid-ocean ridge = the main landform created there.

Example

The Mid-Atlantic Ridge is a famous example of this kind of feature, stretching down the Atlantic Ocean basin as the seafloor spreads.

TL;DR: Mid-ocean ridge.
