No. Convection currents which could lead to volcanism in the crust occur in the mantle. The crust is too cold and brittle for convection currents to occur.
Convection currents are in the liquid and gas states.

Convection currents occur in the mantle of the earth. They can affect the crust and the life above it, though.
The middle of the mantle.
Convection currents can occur in either a gas or liquid medium but not in a solid medium (so you can have them in air, and you can have them in magma, but you can't have them in solid rock) and they only occur when there is a temperature difference, so that hotter, less dense material will rise, and colder, denser material will sink.
They occur in the Mantle.Prettyorc345Your welcome! I had the same problem on my science homework :)
Convection currents are the movement of fluid as a result of differential heating or convection. In the case of the Earth, convection currents refer to the motion of molten rock in the mantle as radioactive decay heats up magma, causing it to rise and driving the global scale flow of magma.

in the outside and inside and underneath and between layers
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.
