What is on Mars surface?
On Mars there is a lot of volcanoes (which are the biggest ones in our solar system) also there are alot of canyons which were caused by fault zones. There are also polar ice caps where the little water that is there is frozen.
How old are the moons craters?
The number of craters on the moon are too many to count. Approximately 300,000 craters with diameters of 1 km or more are visible from ground based telescopes. High-definition photographs from lunar probes reveal millions of craters. Extreme closeups show countless microscopic craters.
How do mountains or craters on the surfaces of the earth and the moon compare with each other?
The biggest difference is the craters on the moon erode at a much slower rate. Here on earth, it takes a few thousand years for a crater to fill in and become not much more than a valley. On the moon, the craters last until ejecta from newer craters fills the holes of the older craters. The mountains of the earth are covered with snow and below the timberline lie trees. There is no snow or trees on the moon. The mountains on the moon look a lot sharper and the rocks stand out because they're not covered in dust. The lunar mountains look much rounder and the entire surface of the moon is covered in a very thin layer of dust.
How much of the entire moon's surface is illuminated by the sun at first quarter?
At any time, half of the entire Moon's surface is illuminated.
Does the moon have a rocky surface?
Yes, exclusively. The entire surface of the Moon is rock in one form or another.
Does Uranus have any impact cratering on it?
No way to tell as the entire planet is shrouded in clouds. But, having said that, many of its moons (e.g., Titania and Oberon) have impact craters. So it's not a far reach to believe that Uranus itself would have impact craters in its rocky central core.
What caused the features of the moon?
Some of the mountains on the Moon appear to be natural formations. Unlike Earth, where wind and rain erode mountains and hillsides, the vacuum of the Moon keeps every feature pristine. The only things that affects the Lunar surface are meteors. Millions of meteor impact craters speckle the entire face of the Moon. Craters on craters IN craters; probably 3.5 billion years worth of lunar impact craters has made the Moon what we see today.

Why are there more craters on mercury than on venus earth and mars?
The earth has a atmosphere that protects us and most meteorites burn before they are able to make contact with the ground, and Mercury has no atmosphere like this and therefore has more craters. Earth's surface is subject to weathering. Erosion obliterates surface features rather quickly, leveling entire mountains in as little as a hundred million years. In addition, sea floor spreading and subduction draws the sea floor beneath plate margins, eradicating any evidence of asteroid or cometary impacts there. We have a few big craters scattered here and there, but very few recognizable ones more than a hundred million years old. Mercury, in contrast, is geologically stable. It has no atmosphere, and thus no rain. Few earthquakes or faults appear to trouble its surface. Any impact over the last four billion years remains on its surface, at least until another impact lays over the top of it.

How many words does the entire Wikipedia have?
4.2 billion
Is there just over 10 billion people who live in Greece?
There's only seven billion on the entire planet!
Does Saturn have hurricanes and craters?
Saturn experiences massive cyclones. Its huge hurricane-like storms that are bigger than Earth. Saturn seems to store up energy for a long time, then let it loose resulting in these violent, huge storms.
How much of the entire moon's surface is illuminated by the sun at first quarter?
At any time, half of the entire Moon's surface is illuminated.
How many surface of a sphere has?
A sphere has just the one entire surface area.
Thin out layer of earth that coversits entire surface?
There is a thin layer of ozone that covers entire surface. It is called ozone layer and protect us too.
