The technology works by passing a small amount of electrical current through electrodes in the water.
When a positively charged anode and negatively charged cathode are placed on the sea floor, with an electric current flowing between them, calcium ions combine with carbonate ions and adhere to the structure (cathode).
This results in calcium carbonate formation. Coral larvae adhere to the CaCO3 and grow quickly.Incorrect

2. Question
1 pointsAccretion burst event is related to-
- Activity related to the formation of a star
- A sudden increase in coral reef
- A large accumulation of rocks in Kuiper Belt

This is called an accretion burst event. It is incredibly rare: only three such events have been observed, out of all the billions of massive stars in the Milky Way.
