Is most of the surface covered by rocks?

What is the surface of the moon covered with?
Most of the surface of the Moon is covered by fine dust created by meteor impacts and by heating of the crustal rocks in the near-vacuum. The lack of water on the Moon prevents this dust from being bound into sedimentary rocks. The depth of the dust does not seem to be very great in any location examined, and averages a few centimeters at most.Regolith
How does the moon get smooth?
Most of the surface of the Moon isn't smooth at all, because of the rocks, hard soil, and many craters that dot the surface.
Why are there rocks on the moon that are older that any rocks on earth?
There is no geologic activity or weathering on the moon to break rocks down, so most of the rocks on the moon are nearly as old as the moon itself. Earth is geologically active and has processes that will destroy and recycle rocks. None of the rocks that made up Earth's original surface are still intact.

What country has the most caves?
Russia has the most caves. It has 19% of its total area covered by carbonate rocks at the surface, which are the primary constituents of caves.
How does erosion occur on the moon?
The moon doesn't have soil like the kind found on Earth. Most of the moon's surface is covered with what is called regolith. This is a combination of fine dust and debris from rocks that was produced when meteors hit the moon.
Were rock samples brought back from the moon during the Apollo space program older than rocks found on earth?
The rocks on the Moon were on the lunar surface many millions of years ago, because the Moon (with no air or water) has almost no erosion and no chemical processes taking place. It also has no volcanic or tectonic activity, which constantly changes most of the Earth's surface. In effect, although it is pummeled incessantly by meteors, the Moon is a vacuum-sealed container for its surface rocks, which on the Earth would have disappeared long ago.
What is the surface of Mercury?
mostly rock and iron!!!!The surface of Mercury is most similar to the surface of the moon. Both are about the same age (very roughly) and both are covered with impact craters.
What rocks are formed belows Earth's surface?
Most sedimentary rocks, most metamorphic rocks, and intrusive igneous rocks.
The surface of mercury is similar to the surface of what?
Mercury's surface is barren, arid, waterless and airless. Being so close to the Sun it is subjected to the full intensity of the Sun's light, ultra-violet and infra-red radiation, as well as blasts of high-speed particles thrown out by solar flares. The surface is heavily cratered from meteoric impacts, and there is also evidence of ancient lava flows in the distant past.
What rock type are most common at earths surface?
Sedimentary Rocks. 75% of rocks exposed to the surface are sedimentary. Basalt is the most common type of rock and it is igneous.
