Answer: 1
Detailed Explanation
Explanation:
BIOROCK TECHNOLOGY
· The Zoological Survey of India (ZSI), with help from Gujarat’s forest department, is attempting for the first time a process to restore coral reefs using biorock or mineral accretion technology.
· It is a method that applies safe, low voltage electrical currents through seawater, causing dissolved minerals to crystallize on structures, growing into a white limestone (CaCo3) similar to that which naturally makes up coral reefs and tropical white sand beaches.
· Biorock, also known as Seacrete or Seament, refers to the substance formed by electro-accumulation of minerals dissolved in seawater.
· A biorock structure was installed one nautical mile off the Mithapur coast in the Gulf of Kachchh on 19th January, 2020.
· The scientists have used solar panels for power in this case.
