積つむ
積む is a more general verb for loading, piling, or accumulating, while 積み重ねる emphasizes the act of stacking one thing on top of another, often with a sense of deliberate layering.
重かさねる
重ねる means to pile or layer things, but 積み重ねる adds the nuance of building up a stack or accumulation, often with a more concrete or sustained effort.

Compound of 積む (tsumu, 'to pile') and 重ねる (kasaneru, 'to stack'), combining the ideas of loading and layering to mean 'to pile up in layers'.
