less denser than
When polar water is diluted by melting ice, the overall density of the water can decrease. Ice is less dense than liquid water, which is why it floats; when it melts, it adds water to the surrounding liquid without significantly increasing the mass. However, the temperature and salinity of the surrounding water can also affect density, but generally, melting ice leads to a less dense mixture compared to the original polar water.

Because the water gets colder isn't that obvious!
Except at EXTREME pressures (like over 200 MPa), ice is less dense than liquid water. In the case of polar water this is even more the case since polar water has a fair amount of salt dissolved into it, raising it's density, while the ice is nearly pure water.
if the ice keeps melting they will have no land so they might drown in the water and might become more endangered overtime.
Melting sea ice is a threat to the polar bears because without the sea ice the polar bears predators will see them and swim away.
yes
no
probaly because global waming which is melting the polar ice caps
Polar air is denser because it is colder.
