Morphology
The meaning 'the bottom surface of a sea or ocean' is directly and transparently derived from combining 'sea' (a large body of saltwater) with 'floor' (a bottom or surface), so the compound denotes the sea's bottom. This noun–noun composition follows a common, cross-linguistically familiar pattern and would be readily understood by a B1 learner who knows both constituents.
Etymology
Sea floor comes from a simple picture: imagine the sea has a solid floor under the water where sand, rocks and sea creatures rest. That's why 'sea floor' means the bottom surface of a sea or ocean.
