What causes checking or surface splits in timber flooring?

From a professional specification perspective:

Checking or surface splits occur when timber moisture content drops dramatically, typically in unoccupied homes during hot dry seasons where internal moisture content can fall to 4%. This severe shrinkage causes the timber surface to split. Floor Sanding Australia recommends maintaining some ventilation and humidity in unoccupied homes during extreme dry periods.
