What is the term for distortion in wood caused by uneven drying?

Explanation:
Warping is distortion in wood caused by uneven drying. As moisture leaves the wood, the surface dries and shrinks faster than the interior, and shrinkage differs along the grain and across it. This uneven shrinkage causes the board to bend, twist, or cup rather than stay flat. Warping is the broad term that covers shapes like bowing, cupping, crooking, and twisting. To minimize it, dry wood gradually and evenly with proper stacking and airflow, and control humidity. If a piece is warped, flattening by planing or re-drying under restraint can help, but prevention during drying is best.
