Question

1. where are the convection currents that move the plates?

crust
mantle
outer core
inner core

Explanation:

Tectonic plates are moved by convection currents that form in the semi-fluid rock of the Earth's mantle. Heat from the core creates these currents, which circulate and drag the overlying crustal plates. The crust is the thin outer layer, while the inner and outer cores are metallic layers that do not drive plate motion via convection in this context.

Answer:

Mantle
