because on one side so many astrodes have hit that side so of the moons crust have eventually over time has eroded away. than on the other side because it hasn't been hit as often.
Right now scientists do not know why the Earth-facing side of the moon has thicker crust. One proposal is that Earth may have once had two moons that collided at relatively low speeds. The geologically different regions on the moon would then have originated from two separate moons.
Thicker. The side of the moon facing Earth has a thicker crust compared to the side facing away, known as the lunar farside. This difference is due to the asymmetry in the thickness of the Moon's crust caused by the cooling of the lunar magma ocean.
The pull of Earth's gravity during the moon's formation caused the crust on the far side of the moon to become thicker than the crust on the near side. On the near side, the lunar crust is about 60 km thick. On the far side, the lunar crust is up to 100 km thick.
Photo surveys seem to indicate that the hidden "far side" of the Moon has a thicker crust and more mountains. We're not sure why the far side is so different from the visible near side, but it is.
According to my Honors Earth Science high school textbook (McDougal Littell: Earth Science by Nancy E. Spaulding and Samuel N. Namowitz), the far side of the moon's crust, at about 150 kilometers, is approximately 85 kilometer's thicker than its near side, at 65 kilometers thick.
The moon's crust averages between 31 and 37 miles in thickness. The crust on the far side is a bit thicker than the near side.

I dont know go ask someone else
The Moon's crust on the near side is thinner and smoother with large plains called maria, formed from ancient lava flows. The far side has a thicker crust with more craters and mountains, as it has been shielded from volcanic activity due to tidal locking.
While the earth rotates, the moon revolves around it. While the moon rotates it has different phases. Improvement : I think this question is about the fact that the Moon's crust seems to be thicker on the "far side". This may be why there's much less sign of volcanic activity on the far side.
left side
The Moon's near side has more Maria (dark, smooth plains) than the far side because the lunar crust is thinner on the near side, allowing for more volcanic activity in the past. This resulted in more volcanic eruptions and lava flows creating the Maria that we see today. The far side of the Moon has a thicker crust, which limited the amount of volcanic activity.
The Moon's crust may be thicker on the far side. So there was less volcanic activity. So there is less lava to cover up craters. Lava flows form the "maria" which are much more in evidence on the side facing Earth.
