A small crack that runs across the growth rings in wood, often due to seasoning, is called a ________.

The term "check" specifically refers to small cracks that form in wood across the growth rings as a result of the natural seasoning process. Seasoning is the process whereby wood is dried out, removing moisture to prepare it for use in construction or other applications. During this process, the wood can shrink, leading to these characteristic checks.

Checks are generally superficial and do not compromise the structural integrity of the wood significantly, although they can affect its appearance. Understanding this term is crucial for those involved in building and construction, as it helps in recognizing the quality and suitability of wood for various applications. The distinction between checks and other wood defects is important for assessing the condition of lumber and ensuring appropriate selection for projects.
