Explanation
The removal of carbon dioxide from the Earth's atmosphere and the provision of long-term storage of carbon in the terrestrial biosphere is known as (A) Carbon sequestration.
Carbon sequestration refers to the capture and storage of carbon dioxide to mitigate the impact of greenhouse gas emissions on climate change. It involves various methods such as afforestation (planting trees), reforestation, carbon capture and storage (CCS), and enhancing natural carbon sinks like soil and oceanic carbon storage. The aim is to reduce the concentration of carbon dioxide in the atmosphere and store it in a more stable form, thus reducing its contribution to global warming.
