Final answer:
Venus has a thick atmosphere that prevents strong winds, resulting in little wind erosion.
Step-by-step explanation:
The underlying reason why Venus has so little wind erosion is because Venus has a thick atmosphere that prevents strong winds. The thick atmosphere of Venus produces a high surface temperature and shrouds the surface in a perpetual red twilight. This thick atmosphere and blanket of clouds create a relatively calm environment with low surface wind speeds, resulting in minimal wind erosion.
