They occur in the upper mantle and the convections come from the inner core but travel to the upper mantle.
in which earth layers does crusal plate movement occur because of convection cells
Convection currents occur in the mantle of the earth. They can affect the crust and the life above it, though.
Convection currents occur in any fluid in which there is a temperature differance. Most convection currents occur in the mantle, the layer of semi-liquid rock below the crust. These currents are the reason behind plate tectonics.
The basic answer is the Mantle, but, really, it's the only very uppermost part of the Mantle that encounters plasticity and convection--when relating to tectonic plate movement, at least. The Asthenosphere is the fluid layer on with plates move across the surface of the earth, being pulled apart (Diverging) or colliding together (Converging). The Asthenosphere is what drives convection and in a very similar way, subduction. Like the person above said, if your teacher/professor hasn't said the word Asthenosphere, then the answer he/she is looking for here is the Mantle, or Upper Mantle. I'd go with Upper Mantle to be safe.

To answer your question the answer is the Mantle.
Convection currents occur in any fluid in which there is a temperature differance. Most convection currents occur in the mantle, the layer of semi-liquid rock below the crust. These currents are the reason behind plate tectonics.
A grainy cloud like substance that comes from the convection area under the photosphere.
