Because the water gets colder isn't that obvious!

Because there is no water in polar regions
The Antarctic Bottom Water, North Atlantic Deep Water, and Antarctic Intermediate Water are three density currents that form in polar regions.
In equatorial regions the water is warm, therefor the temperature will be higher. The temperature of t he polar regions will be less than the equatorial region because the water density is less.
The salinity of water in polar regions varies seasonally because of the melting of sea ice during warmer months.
It an Polar Animal .Because it lives in Water and Water formed by the Snow mountains in the Polar Regions. So , It is called Polar Animal
Water is polar and oil is nonpolar. This is why they separate upon standing. The reason that the oil sits on top of the water is that it is less dense than water..
Anything to do with the north and south poles. Water molecules (and some others) have polar regions.
Surface salinity in polar regions varies seasonally due to the formation and melting of sea ice.
Radar astronomers found ice water that never melts in the deep craters in the polar regions of Mercury.
