Spreading finely ground basalt rock on farmlands extensively
Increasing the alkalinity of oceans by adding lime
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?
Only one
Only two
All three
None
Correct Answer: Option (c)
Carbon sequestration is the technology designed to tackle global warming by capturing CO2 at power stations, industrial sites or even directly from the air and permanently storing it underground. It describes the long-term storage of carbon dioxide or other forms of carbon to either mitigate or defer global warming. Some of the methods of Carbon sequestration are:
Spreading finely ground basalt rock on farmlands extensively
Increasing the alkalinity of oceans by adding lime
Capturing carbon dioxide directly or indirectly from the atmosphere and then storing or burying it in a suitable deep, underground location.
