Question

Quizplus · Accepted Answer

Plywood is made by layering thin plies of wood on top of each other with each layer positioned perpendicular to the previous layer. This cross-grain construction reduces the wood's natural tendency to expand and contract with changes in moisture and temperature, making it more stable and less prone to warping or splitting.
