ONLiNE UPSC · Accepted Answer

Biorock technology is a method developed by architect Wolf Hilbertz in the 1970s that uses a low-voltage electric current to encourage the growth of marine structures, especially coral reefs. By applying this current to metal frames submerged in seawater, minerals like calcium carbonate and magnesium hydroxide naturally present in the water accumulate on the structures. This process creates a solid surface that promotes coral attachment and growth.
Statement 1 is correct: Biorock technology utilizes the electrolysis of seawater, causing minerals to deposit onto submerged metal structures. This process creates a solid substrate that facilitates coral attachment and growth.

Statement 2 is not correct: The mineral accretion process in Biorock technology operates using low-voltage electrical currents, not high-voltage.

Statement 3 is correct: Biorock structures have been employed as wave breakers and in shoreline stabilization efforts, leveraging their durability and ability to promote marine habitat formation.
