Question 14 multiple choice worth 3 points) which of the following contributes to the movement of tectonic plates? 1. deposition of sediment on the ocean floor ii. push of newly formed crust iii. mantle convection i only ill only i and ii ll and iii i, ii, and ii

Option (2)

Explanation:

The earth's crust is comprised of numerous small and large plates, and they are known as the lithospheric plates. This lithospheric plates are divided 2 types, namely the continental and the oceanic plate. These plates continuously floats over the viscous asthenosphere layer due to the formation of convection current in the mantle. This current forms because of the heat that is provided from the core of the earth.

Thus, the mantle convection contributes the movement of the lithospheric (tectonic) plates.

Hence the correct answer is option (2).
