The process of removing the central core or pit from fruits like apples, or extracting cylindrical samples from soil, ice, or rock.
From 'core' (the central part) plus '-ing,' forming a gerund; 'core' comes from Old French 'cor' and Latin 'cor' (heart).
Scientists use ice coring to read climate history—they pull up cylinders of ancient ice from Antarctica and Greenland that contain trapped air bubbles from atmospheres thousands of years old, like reading Earth's diary!
