which of the following leads to upwelling?\n○ a. strong tides\n○ b. strong currents\n○ c. winds and currents…

Brief Explanations:

Upwelling occurs when winds and currents move along the coast. This movement causes surface water to be pushed away, allowing deeper, nutrient - rich water to rise to the surface. Strong tides mainly affect water levels due to gravitational forces and are not the main cause of upwelling. Strong currents alone without the specific coastal - related wind and current interaction don't lead to upwelling. Wind convergence typically leads to other weather - related phenomena like cloud formation and precipitation rather than upwelling.

Answer:

C. Winds and currents moving along the coast
