Well as you go further down into the ocean, it will be colder.
Usually but not always!! Temperature and salinity affect the density of seawater, and in many systems, density increases with depth (as temperature decreases and salinity increases). IT is however possible to observe patterns where dense water at depth is either very salty but warm, or very cold, but nearly fresh.
it is how much salt mass in the ocean water
The sun is not as close to the bottom of the ocean as it is at the top.
Temperature decreases with depth.
The relationship between depth and sunlight is that sunlight penetration decreases as depth increases in water. This is due to the absorption and scattering of light by water molecules and particles. Consequently, less sunlight reaches deeper parts of the water column, affecting the availability of light for photosynthesis and primary production.
Depth is a measure of distance between the surface and the ocean floor.
Latitude and depth!!
Thermocline
The relationship between the rise of ocean temperatures and the rise in the level of atmospheric carbon dioxide is that when there is a rise in atmospheric carbon dioxide the warmer the temperature of the ocean is
The term you are referring to is "thermocline." It is the layer of water in the ocean where there is a rapid change in temperature with depth, serving as a barrier between warmer surface water and colder deep water.
the deeper you go, the colder the ocean water gets
As ocean depth increases, pressure also increases. This is because as water depth increases, there is more water above exerting force due to gravity. Pressure in the ocean increases about 1 atmosphere (atm) for every 10 meters of depth.
