Adding iron-rich particles to the ocean is a geo-engineering method of removing carbon from the atmosphere.

Question

Quizplus · Accepted Answer

Iron-rich particles stimulate the growth of phytoplankton, which absorb carbon dioxide from the atmosphere through photosynthesis. As the phytoplankton dies and sinks to the ocean floor, the carbon is stored in the sediments, effectively removing it from the atmosphere. However, there are concerns about the potential environmental impacts of this method and its long-term effectiveness.
