It gets colder because the Sunlight heats the ocean and the deeper you go, the less penetrating the Sunlight is, therefore making the ocean water colder.
it becomes colder
The water gets cooler
it depends on what opart of the ocean you are talking about...the deeper you get the colder it becomes nad the closer you get to the south or north pole the colder it becomes
Ocean water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water. Source: Science book.
it becomes colder
denser, due to the decrease in temperature causing the water molecules to contract and become more tightly packed. This increased density causes the cold water to sink to the bottom of the ocean, creating ocean currents as it displaces warmer, less dense water.
it becomes less dense
lack of sunlight
gets colder
When the ocean water freezes, it increases the salinity. When the ocean water freezes at the surface, ice will float on top of water because ice is less dense than liquid water. The dissolved solids are squeezed out of the ice and enter the liquid water below the ice. This increases the salinity of the water. The density of the water also increases.
the deeper you go, the colder the ocean water gets
When water reaches an arctic region and cools, it becomes denser and sinks due to its increased salinity and lower temperature. This process is known as thermohaline circulation, where cold water sinks and drives deep ocean currents.
