What is the primary geologic consequence of plates sliding horizontally past one another at transform zones?

Answer

Sudden release of built-up stress as earthquakes

Transform boundaries involve intense friction and shear stress. This grinding action causes tremendous stress to accumulate, which is periodically released suddenly in the form of earthquakes.
