Erosional Activity on Mercury, Venus, and Moon

Erosion in Earth is in the first place caused by water or moisture, wind, and other earthly activities. However, in other planets like Mercury and Venus, as well as our own satellite, which is the Moon, at that place is less erosion activity. Considering their distance from the Sun, the two mentioned planets argon the closest ones to the Sun, and in case of Moon, it has the same distance as the Earth from the Sun which is 1 astronomical unit. We could say that in these heavenly bodies, the moisture is least to dwell since they are prone to the intense heat of the Sun, considering that the Moon gets its light from the Sun. past from that, the Sun has strong soberness that enables it self to pull the planets and other heavenly bodies in the solar System. Considering that the Mercury and Venus are the planets considered closest to the sun, two planets have received also the strongest attraction of the gravitational pull. In this case, the materials of the planets are more intact that could prevent to be eroded.In relation to the terrestrial size, it is correlated to the gravity such that the bigger the planet or the heavenly body, the greater of its gravitational pull. The Mercury, Venus, and Moon, which are relatively small bodies in Solar System, it has lesser gravity pull than the Earth. However, with the influence of the Earths gravity to the Moon, it prevents the moon from its orbiting and other erosional activity in the said satellite. Mercury and Venus, as it was mentioned before, both planets have been affected by the gravitational force of the Sun. The fall heavenly bodies, such as meteor and asteroids, that also causes erosion in planets would be avoided by attraction of gravity pull of the Sun. Instead of contact with Mercury or Venus, it would be then collided with the Sun. In this case, there would be lesser erosional activity.ReferenceJuly 1, 2007July 1, 2007
