What is the difference between the surface layer and the deep layer of the ocean?

• The surface layer is colder, receives less sunlight, and has less oxygen compared to the deep layer.

• The surface layer is deeper, receives less sunlight, and has less oxygen compared to the deep layer.

• The surface layer is shallower, receives more sunlight, and has less oxygen compared to the deep layer.

• The surface layer is warmer, receives sunlight, and has more oxygen compared to the deep layer.
