Question

explain how sea floor features form. 5 of 5 we have moved to the southern ocean that surrounds antarctica. click continue to move it closer to the circled feature that you will be asked about what is this large - scale feature located in the middle of the screen? an oceanic plateau a spreading ridge a large reef structure a continental shelf

Explanation:

To determine the sea - floor feature:

1. Recall the definitions:

• An oceanic plateau is a large, relatively flat area on the ocean floor, often formed by volcanic activity (like large - scale lava flows or volcanic build - up) and can be eroded over time. In the Southern Ocean around Antarctica, oceanic plateaus are common features.
• A spreading ridge is a mid - ocean ridge where new oceanic crust is formed (divergent plate boundary), and it has a more rugged, rift - like appearance with volcanic activity along the ridge axis, which doesn't match the “large - scale, relatively flat” description here.
• A large reef structure is mainly composed of coral (or other reef - building organisms) and is more common in warmer, shallow ocean areas, not in the cold Southern Ocean around Antarctica.
• A continental shelf is the shallow, submerged extension of a continent, and Antarctica's continental shelf would be closer to the continent, not in the “middle of the screen” (open ocean) as described.
• So, the feature is an oceanic plateau.

Answer:

A. An oceanic plateau
