Scientists think that convection currents flow in Earth's

a. continents.

b. mantle.

c. lithosphere.

d. inner core.

The correct answer is letter D. Scientists think that convection currents flow in Earth's inner core. This then causes the movement of tectonic plates which causes shifts in topographies of different locations. Convection currents also have the tendency to transfer heat to the surface of the Earth which causes magma to spill out from openings of volcanoes.
