Mercury’s proximity to the sun also deprived the planet sufficient atmosphere that would cause the winds that would erode its surface.
Finally, the small physical dimensions particularly of the Moon and Mercury further result to the absence of erosion. Small planetary objects do not have sufficient gravitational pull to retain liquid surface water and atmospheric gases. (Zimmerling, p. 261) Without these factors, both have virtually no weather and no change to its surface through erosion.
Meanwhile, Venus may have some definitive evidence of limited crustal movements that are comparable to the plate tectonics seen on Earth, however, most of the planet’s tectonic activity – the phenomenon – that usually causes erosion – are concentrated over stationary “hot spots” where molten rocks wells up. Its proximity to the sun also contributed to its lack of water, which accounts to the majority of erosions that occurs on Earth. (Corfield, p.
