Option (1), (2) and (3)

Explanation:

The subduction zones are created when a denser oceanic plate subducts under a lighter continental or oceanic plate. It forms at the convergent plate boundary. The point above this subduction zone where the depression forms is known as the oceanic trenches. This trenches extends up to a great depth. The subducting plates undergoes partial melting as a result of which the plate melts and the magma rises up towards the over-riding plate forming volcanoes or chain of volcano. This type of plate boundary generates deep focus earthquakes.

Thus, the correct answer are option (1), (2) and (3).

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
