Question

which feature of earth is created at mid-ocean ridges?
○ new island chain
○ new underwater caves
○ new continents
○ new ocean floor

Explanation:

Mid-ocean ridges are divergent plate boundaries where magma rises from the mantle, cools, and solidifies to form new oceanic crust, which becomes the new ocean floor. Island chains typically form at hotspots or subduction zones, underwater caves form from erosion, and continents form from the aggregation of crustal material over long periods, not at mid-ocean ridges.

Answer:

new ocean floor
