← GeographyWhich geologic outcome primarily occurs along a transform plate boundary?
A)Shallow-focus earthquakes from strike-slip motion✓
B)Deep-focus earthquakes from subduction zones
C)Volcanic arcs from lithospheric melting
D)Rift valleys from crustal extension
💡 Explanation
At transform boundaries, plates slide past each other horizontally because shear stress builds up, leading to release of energy as shallow-focus earthquakes through strike-slip motion. Therefore earthquakes form, rather than volcanism, deep-focus events, or rifts which need different tectonic settings.
