Give one reason why this image supports the theory of plate tectonics (plsss help me - 20 points are available!)

This image shows fault lines.

Explanation: Fault lines are physical and cartographic divisions of different tectonic plates. This supports the theory of plate tectonics because the theory explains the structure of the earth's crust and many associated phenomena are resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle, and which are fractionated by multiple crevices called fault lines.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
