A trough of rock layers is called a "syncline." In geology, a syncline is a downward-curving fold where rock layers dip inward toward the center, forming a U-shaped structure. This contrasts with an "anticline," where rock layers arch upward. Synclines are important in understanding the geological history and structural features of an area.
