Identify the false statement. Differentiation of large planetesimals and protoplanets:
is the process by which they developed internal layering.
began with heating up their component materials.
used heat created by the transformation of kinetic energy from collisions into thermal energy.
was inhibited if radioactive elements were present because their decay required heat input from the surroundings.
resulted in a central ball of iron alloy (the core) and an outer shell of lighter rocky materials (the mantle.)
