What effect does the presence of continental boundaries at most latitudes have on the circulation? What happens where there is no continental boundary? Earth is 70.8% water-covered. In the zonal direction, there is no land between 85-90°N and between 55-60°S. The presence of continental boundaries strongly influences the ocean circulation. Ridges separate deep waters of the ocean into distinct basins. Water deeper than the sill between two basins cannot move from one to the other. Tens of thousands of sea mounts are scattered throughout the ocean basins. They interrupt ocean currents, and produce turbulence leading to vertical mixing in th ocean....
