Question

which layer contains the convection currents that directly move tectonic plates? layer 1 layer 4 layer 2 layer 3

Explanation:

The Earth's layers, from innermost to outermost, are: Layer 1 (inner core, solid), Layer 2 (outer core, liquid), Layer 3 (mantle, with the asthenosphere in its upper part that has convection currents driving tectonic plates), Layer 4 (crust, where tectonic plates are located). The convection currents that directly move tectonic plates are in the upper mantle (Layer 3), as the semi-fluid rock here flows and drags the overlying crustal plates.

Answer:

Layer 3
