The formation and collapse of gas bubbles in fluids is called which?

Explanation:
Cavitation is the rapid formation and violent collapse of gas or vapor bubbles in a liquid when local pressure drops below the liquid’s vapor pressure. In regions around pumps, turbines, or prop valves where pressure falls quickly, tiny bubbles form; when the pressure rises again, these bubbles collapse with enough energy to generate shock waves and damage surfaces. This distinguishes it from water hammer (a pressure surge from sudden flow change), corrosion (chemical degradation), and erosion (material wear from mechanical action). So the phenomenon described is cavitation.
