When we see a region of a planet that is not as heavily cratered as other regions we conclude that?

It was protected from meteoric bombardment by some other body, or that it had undergone volcanic activity and was covered with a newer surface than elsewhere, or that there were fluids which smoothed out the craters.

How are planets near other stars found?
There are several ways, the most popular are: 1) Just like a star affects the motion of a planet so does the planet affect the motion of the star, but only in small degree. Astronomers look at stars and see if they have a periodic shift in their movement and conclude that a planet is causing it. 2) If the orbit of a planet is "edge on", then it will eclipse the star and cause a periodic reduction of its light by up to 2%.
Why is the earth an oblate spheroid?
It's an oblate spheroid because of inertial forces. The planet spins on it's axis. This motion causes the regions closer to the equator to bulge outwards resulting in the current shape of the Earth (and many other planets).
Which planet has the longest seasons?
Pluto must be a likely answer. We know it does show signs of changes on its surface over time. Its eccentric orbit is as important a factor as its axial tilt. Pluto's axial tilt is extreme, similar to that of Uranus. So, for long periods of Pluto's orbit, one of the polar regions is (roughly) facing the Sun and the other will be in darkness.
Is the moon a terrestrial planet?
No. The moon is not a planet; it is a moon. If it had its own orbit around the sun it would be considered a terrestrial planet.
Which planet would orbit around the sun the slowest?
Neptune. (Pluto is no longer considered a planet, but, rather, a dwarf planet.)
What is the heavily cratered planet closest to the sun?
that's planet mercury
Which planet is the most heavily cratered of the terrerstrial planets?
Mercury.
What planet has a heavily cratered surface like our moon?
mercury
Which inner planet has a surface covered with craters?
Mercury is the most heavily cratered of the inner planets.
What planet is similar to the moon?
Mercury looks like the Moon: it is heavily cratered with regions of smooth plains, has no natural satellites and no substantial atmosphere. However, unlike the moon, it has a large iron core.
What inner planet has a surface with craters?
All four inner planets have craters. Mercury is the most heavily cratered.
What is the most cratered planet?
Mercury is the most cratered planet in the solar system.
Which moon orbits farthest from its planet?
The moon that orbits farthest from its planet is Calisto. Calisto is also the most heavily cratered object in the entire solar system.
Which planet is heavily cratered earth or mercury?
The most terrestrial planet in our Solar System is Mercury as evidenced by Mariner 10 satellite that flew by Mercury 3 times during 1974 and 1975. A new satellite, Messenger, was launched in 2004 and will be orbiting Mercury next year.
Which planet has a cratered surface similar to Earths moon?
The planet Mercury has the most similar cratered surface compared to the moon.
Does Mercury have landforms?
Mercury has no atmosphere, and its surface is heavily cratered much like Earth's moon. It is estimated that the planet has been geologically dormant for a few billion years.
Is planet Mercury smooth?
Without an atmosphere to protect it from meteor impacts, the planet Mercury is heavily cratered. This includes the basin Caloris, which is a 1500-km wide impact crater with associated lava flows and crustal splitting.
