GEOLOGY

Detailed explanation-1: -The top surface layer is called the epipelagic zone, and is sometimes referred to as the “ocean skin” or “sunlight zone .” This layer interacts with the wind and waves, which mixes the water and distributes the warmth. At the base of this layer is the thermocline.

Detailed explanation-2: -Water is warmest at the surface, as it is warmed by the sun, and the sun’s rays can only penetrate depths less than 1000 m (section 6.5). Since the surface water is warmer it is also less dense than the deep water (section 6.3), so it remains at the surface where it can be warmed even more.

Detailed explanation-3: -The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates. Because this zone gets sunlight, photosynthesis can occur and plants can grow here.

Detailed explanation-4: -Epipelagic Zone With that sunlight comes heat from sun, which is responsible for wide variations in temperature across this zone, both with the seasons and latitudes-sea surface temperatures range from as high as 97°F (36°C) in the Persian Gulf to 28°F (-2°C) near the North Pole.

Detailed explanation-5: -The ocean has three primary layers. 2. The layers are the surface layer (sometimes referred to as the mixed layer), the thermocline and the deep ocean.
