Why does cold, salty water sink in the ocean?, it is warmer, it has higher density, it moves faster, it has less mass, A density current is best described as:, movement of waves, movement due to wind, movement due to temperature only, movement up/down due to density differences, Which of the following will MOST likely form a density current?, cold salt meeting warm fresh, only wind blowing, warm fresh meeting warm salt, surface waves, When wind blows over the ocean surface, it mainly causes:, density change, sinking of water, surface current, deep water movement, Surface currents affect:, only the bottom, entire ocean equally, only freshwater, only the top layer, Which condition increases the density of ocean water the most?, low salinity only, high temp, low salinity, low temp, high salinity, high temp, high salinity, If the wind suddenly stops, what will happen to surface currents?, they will stop or decrease, they will sink, they will increase, they will become density currents, Which statement is correct about density currents and surface currents?, both are caused by wind, density vertical, surface horizontal, both depend only on salinity, both affect only surface water
