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 (mineral accretion) uses low-voltage electrical currents passed through seawater to trigger the crystallization of dissolved minerals.

This creates a limestone-like structure on artificial frames, providing a rapid-growth substrate that actively stimulates the survival and restoration of damaged coral reefs.

Biorock uses underwater electricity to grow limestone skeletons for coral restoration.

Answer: (a).
