The polar zone is located between 661/2°N latitude and 661/2°S latitude.
Earth's polar regions are the areas of the globe surrounding the poles also known as frigid zones. The North Pole and South Pole being the centers, these regions are dominated by the polar ice caps, resting respectively on the Arctic Ocean and the continent of Antarctica. Polar sea ice is currently diminishing, possibly as a result ofanthropogenic global warming
High latitude zones will have the climate with the lowest temperatures. High latitudes are home to climate zones such as the tundra and the taiga.
Halogen molecules are not polar.
H2O is a polar molecule; +H3O is even more so.
If the difference in electronegativity is greater than 0.3 than it is Polar. Nitrogen and Bromine the difference is less than .3 so it is nonpolar
Salt cannot dissolve in oil. This is because salt is a non-polar substance, because it's bonds are non-polar (this is not to say though that polar bonds always means its a polar substance, but that's another issue). Oil is a polar substance (meaning one end of its molecule is has a slight negative charge, the other a slightly positive charge. It is known that LIKE dissolves LIKE. (e.g. Polar dissovles Polar). There are VERY few exceptions to this.
