of how heat is transferred
from deep in the earth to
the surface?
Convection brings
hot magma up
through the mantle
toward the crust,
where it cools and
sinks.
Conduction brings
hot magma up from
the core to the
crust, where it cools
and sinks.

The best description of how heat is transferred from deep in the Earth to the surface is:

Convection brings hot magma up through the mantle toward the crust, where it cools and sinks.

This statement accurately captures the process of convection, which involves the movement of molten rock (magma) within the mantle as it is heated from below and rises toward the crust, losing heat and cooling before sinking back down.
