Why are impact structures more common on the surface of Mars than on the surfaces of Venus Earth and Jupiter?

Earth has wind, and water, and tectonic plates. This causes impact craters to be destroyed relatively quickly, over the course of hundreds of thousands of years.
Jupiter is a gas giant, and has no crust. Since there's nothing for the meteor to crash into, there's no impact crater at all!
As for Venus, it actually does have a large number of impact craters, they just can't be seen easily underneath the thick atmosphere. However, Venus does have some volcanic activity which damages the craters. This process is so slow that it takes about 500 million years to destroy them all.
Mars, on the other hand, has no processes that destroy craters other than a very thin atmosphere with a little bit of wind. Therefore, the craters there last far longer. In addition, Mars is nearer to the asteroid belt, and is more likely to attract meteors from there than Earth and Venus.

Which galilean satellite has active volcanos?
Io is the innermost of the four large moons (Galilean moons) of Jupiter. Its closeness to Jupiter means that its surface is in a constant state of flex, the gravity from Jupiter distorts its surface, generating heat and flaws in the surface of the moon. This means that volcanoes are a common occurrence on Io.
What are Jupiter and Pluto?
Jupiter and Pluto are planets.
What are the most common elements present on ther planet Jupiter?
The most common elements present on Jupiter are molecular hydrogen (89.8%) and helium (10.2%).
Does homologous mean that structures are similar due to having common ancestry?
homologous structures- same structure/different functions in common ancestors analogous structures-same functions/differnt structures not in common ancestors vestigial-show evolutionary history/structures that arent used anymore (i.e. human appendix/human tailbone)
Is surface a common noun?
Yes, surface is a common noun.
What surface feature do Jupiter and the sun have in common?
They are both gaseous, they both have spots, and they both have fierce surface "winds".

What characteristics do the giants have in common?
The first four outer planets-Jupiter, Saturn, Uranus, and Neptune-are much larger and more massive than Earth, and they do not have solid surfaces.
What do peak roof and convertible top and airplane wings have in common when air moves faster across their top surfaces?
Peaked roofs, convertible tops, and airplane wings have in common when air moves faster across their top surfaces is that air is made to flow faster over the wing's top surface than under its lower surface
What are Jupiter and Pluto?

What type of surfaces radiate heat?
Metal is a main surface of heat with examples being tin, aluminum, zinc or any other common conductor.
The two common forms of friction between two sliding surfaces presented in this course are?
Friction refers to the resistance that one surface or object encounters when moving over another. The two common forms of friction between two sliding surfaces are static friction and rolling friction.
Structures that share a common ancestory or a similar because they are modified versions of structures from a common ancestor are?
Homologous structures.
