What type of turbulence is primarily caused by moving water and air currents?

This question is about how turbulence forms when the air interacts with the surface and obstacles. Mechanical turbulence arises when air moves over the Earth's surface and encounters roughness like terrain, buildings, trees, or even water surfaces. That friction and these disruptions break up the smooth flow, creating eddies and mixing in the lower atmosphere. The other types have different causes: thermal turbulence comes from buoyancy due to temperature differences, wake turbulence comes from the vortices produced by another aircraft, and clear air turbulence results from wind shear in jet streams with no visible cues. Since the scenario emphasizes surface interactions and moving fluids causing near-ground eddies, the type tied to those surface-induced effects is the right choice.
