Meaning of BULGING in English


in geology, mass movement of rock material caused by heavy weights on soft rock strata that crop out in valley walls. Such material is squeezed out and deformed; it flows as a plastic, and the disturbance may extend down tens of metres. Folds and small faults may form at the foot of the slope where the rock material is under stress.
