Consider the following comparisons of the Surface Oceanic Currents and Deep Oceanic Currents?
1. While surface currents are primarily driven by winds, deep currents are primarily driven by density differences
2. While surface currents are swift, deep currents are relatively slower
Which among the above observations is / are correct?
Ocean currents are of two type’s viz. Surface Currents and Deep Currents. Surface currents affect surface water above the pycnocline (<10% of ocean water). These currents are primarily driven by major wind belts. The Deep currents affect deep water below pycnocline (90% of ocean water) and are primarily driven by density differences. The deep currents are larger and slower than surface currents.
