is sea ice a combination of polar ice and ocean current
1 answer
Sea ice is not a combination of polar ice and ocean currents. Sea ice forms when ocean water freezes due to cold temperatures, creating a layer of ice on the surface of the ocean. It is made up of frozen seawater and is different from polar ice, which refers to ice sheets and glaciers on land at the Earth's poles. Ocean currents can affect the movement and distribution of sea ice, but they are not a component of sea ice itself.
