Question

what might happen if global warming disrupts the formation of sea ice? density - driven currents wont form, slowing heat transfer trade winds will become stronger the coriolis effect will stop ocean gyres will disappear

Explanation:

Density - driven currents (like thermohaline circulation) rely on differences in water density. Sea ice formation increases the salinity of the remaining water (as salt is excluded from ice), making it denser. If sea - ice formation is disrupted, the density differences that drive these currents would be lessened. Heat transfer in the ocean (which is partly done by these density - driven currents) would slow.
The Coriolis effect is due to the Earth's rotation and not directly related to sea - ice formation. Trade winds are mainly influenced by pressure gradients and the Hadley cell circulation (not directly by sea - ice). Ocean gyres are driven by wind patterns and the Coriolis effect (not solely by sea - ice).

Answer:

Density - driven currents won’t form, slowing heat transfer.
