Attempt this previous-year question. The correct option stays hidden until you choose.
Consider the following activities :
1. Spreading finely ground basalt rock on farmlands extensively
2. Increasing the alkalinity of oceans by adding lime
3. Capturing carbon dioxide released by various industries and pumping it into abandoned subterranean mines in the form of carbonated waters
How many of the above activities are often considered and discussed for carbon capture and sequestration?
Pick an option to check yourself.
• Correct Answer: C
• Enhanced rock weathering (basalt), ocean alkalinity enhancement (lime), and geological CCS (carbonated water in mines) are all valid carbon sequestration methods.
• Each method converts CO₂ into stable carbonate or bicarbonate forms.
• All three are actively discussed in climate mitigation literature.
