The movement of minerals from the ocean floor upward by currents is called what?

Explanation:
Upwelling is the vertical movement of water from deep in the ocean up to the surface, bringing dissolved minerals and nutrients from deeper waters into the sunlit layer. This happens when winds push surface water away from an area or when coastal geometry causes deep water to rise to replace it. The nutrients carried upward fuel plankton growth and support rich marine ecosystems in those regions. The other terms describe different processes: downwelling is the sinking of surface water, while erosion and sedimentation involve wearing away and deposition of materials, not the upward transport of minerals from the depths.
