<u>Answer</u>: 2

The convection currents shown in points 1 and 3 transfer heat from the outer core (number 4) to the lithosphere. Here, the lower density hot magma breaks apart the plates at <em>point 2</em> creating a divergent plate boundary. <u>This new magma mass will drive a lateral movement of the plates</u>. The edges of the plates which have a higher density basalt rock will sink into the mantle and get consumed in trenches/subduction zones
