Detailed explanation-1: -Shrinking and swelling occur as the wood changes moisture content in response to daily as well as seasonal changes in the relative humidity of the atmosphere, i.e., when the air is humid, wood adsorbs moisture and swells; when the air is dry, wood loses moisture and shrinks.
Detailed explanation-2: -Wood is hygroscopic, which means its MC will fluctuate based on the relative humidity (RH) of the surrounding air. As humidity increases, the MC increases, and the wood expands, and as the humidity decreases, MC decreases, and the wood shrinks.
Detailed explanation-3: -The moisture content of wood changes in response to relative humidity. When the air is humid, the wood absorbs moisture and swells. When the air is dry, wood loses moisture and shrinks. Excessive shrinking or swelling can affect the look of the wood or possibly cause cracks or splitting.
