← GeographyWhich effect arises when a transform fault limits plate subduction rate between segments?
A)Increased frequency of major earthquakes✓
B)Formation of deep ocean trenches
C)Accelerated seafloor spreading velocity
D)Decreased volcanic arc magma production
💡 Explanation
When a transform fault limits subduction plate motion, strain builds up because tectonic movement is still occurring. This results in periodic release of energy as higher magnitude earthquakes. Therefore increased earthquake frequency results, rather than formation of trenches, increased seafloor spreading, or altered magma production which depend on convergence rates.
