The Moon’s craters last longer mainly because its surface lacks the wind, flowing water, weather, and vegetation that wear down and bury landforms on Earth. Earth’s moving crust and resurfacing by volcanoes and sediment also erase impact evidence. The Moon still changes, but its ancient impact record is far less thoroughly erased.
What makes a crater last?
A crater forms when an impact excavates and deforms the ground. Afterward, erosion and later geological activity can soften its rim, fill its basin, bury it, or replace the crust beneath it. The Moon has far fewer of these erasing processes than Earth, so many lunar craters remain recognizable for billions of years. NASA describes the lunar record as preserved over that span, not as a guarantee that every crater survives unchanged (NASA Science: Why Study Moon Craters?).

Earth’s weather wears down and covers craters
Wind and water erode crater rims and move material into depressions. Vegetation and other surface processes can further obscure the shape. Sediment may bury a crater, while weathering gradually makes its boundaries harder to distinguish. These changes happen slowly by human standards, but rapidly on geological timescales. NASA notes that wind, water, and vegetation erase terrestrial crater evidence (NASA Earth Observatory: Fresh Craters on the Moon and Earth).

Earth recycles and resurfaces its crust
Plate tectonics moves and recycles Earth’s crust, eventually destroying even very large impact structures, with few exceptions. Volcanic activity can cover older terrain with new rock, and sedimentary deposits can bury it. The Moon has no Earth-like system of plate tectonic recycling, so its ancient surface is not continually replaced in the same way.

Why does Earth have fewer visible craters?
Preservation is only part of the answer. Earth’s atmosphere filters incoming objects before they can make a crater: many small objects break up during atmospheric entry, and objects that do reach the surface may be disrupted during impact. That is different from erosion after a crater forms. The atmosphere mainly changes which impactors make it to the ground; weathering, burial, tectonics, and resurfacing alter or erase the resulting structures (NASA Earth Observatory).
Earth is not uncratered. Impact structures exist, but many have been degraded, buried, or destroyed by geological change, making the surviving record much less obvious than the Moon’s. NASA summarizes the contrast: “On Earth, impact evidence is mostly obscured by processes like erosion, plate tectonics, and recent volcanic activity” (NASA Science).

How Earth and the Moon compare
| Factor | Earth | Moon |
|---|---|---|
| Atmospheric entry | The atmosphere breaks up many incoming objects before they reach the surface; some surviving impactors are disrupted during impact. | There is essentially no atmosphere to filter incoming impactors in the same way. |
| Wind and flowing water | Erode crater rims and move material that can fill or obscure craters. | No liquid water or wind to drive comparable surface erosion. |
| Vegetation and weathering | Can obscure crater features and alter the surface. | No vegetation or Earth-like weather system. |
| Crustal recycling | Plate tectonics eventually destroys most impact structures. | No Earth-like plate tectonic recycling. |
| Volcanic and sedimentary resurfacing | Volcanism and sediment can cover or bury impact structures. | Local geological change and later impacts still modify the surface, but not through Earth’s same ongoing resurfacing system. |
Are lunar craters perfectly preserved?
No. The Moon’s craters can be altered by later impacts, which excavate new craters and scatter ejecta over older terrain, as well as by other localized geological activity. A crater’s condition depends on its size, age, location, and what has happened nearby. The lunar surface preserves a much more legible impact history than Earth’s, but it is not frozen in time (NASA Science: Moon Craters).

Scientists use crater abundance and condition to interpret the relative ages and impact histories of planetary surfaces. In general, a surface with more accumulated craters has been exposed to impacts longer than a less-cratered surface, though researchers must account for later impacts and resurfacing that can remove or modify older features. The Moon’s comparatively well-preserved record makes it especially useful for studying the history of impacts across the Solar System (NASA Science: Why Study Moon Craters?; NASA Science: Moon Craters).
