Question

"Biorock technology" is talked about in which one of the following situations?

Options

a

Restoration of damaged coral reefs

Answer
b

Development of building materials using plant residues

c

Identification of areas for exploration/extraction of shale gas

d

Providing salt licks for wild animals in forests/protected areas

Explanation

Biorock technology (or mineral accretion) is an innovative method used for the restoration of damaged coral reefs. It involves passing a low-voltage electrical current through seawater to precipitate dissolved minerals onto steel structures, forming a limestone substrate where coral fragments can rapidly grow and thrive.

"Biorock" is specifically synonymous with electrified artificial reefs designed to accelerate marine coral regeneration.

Answer: (a).
