Old craters tend to have smoother edges and floors due to erosion and infilling over time. They may also have been partially erased or modified by tectonic or volcanic activity, making them less distinct. Studying the surrounding geological features and conducting dating methods on the crater materials can also provide clues to their age.

How do you determine old craters from new craters?
Old craters typically have more erosion, with smoother edges and a shallower depth compared to new craters. New craters have sharp, well-defined edges with steep walls and a more prominent central peak. Additionally, the presence or absence of overlapping craters can also help distinguish between old and new craters.
Why are craters important to space?
Depends on which kind of craters you are thinking about. Craters aren't important as such. But impact craters tell us that not all things in space stays nicely in their expected positions. Some drift around and occasionally collide with planets, causing impact crates and other damage. Volcanic craters tells us that the planet has some seismic activity.

Why have very old craters on the moon not be erased as similar craters on earth have been?
Unlike Earth, the moon does not have air, water, glaciers, or plate tectonics to erase craters. The only forces that significantly alter the moon's surfaces are impacts that form new craters.
Does the planet Venus' have craters?
Yes, the planet Venus has craters on its surface, although they are not as common as on other planets like the Moon or Mars. The dense atmosphere and volcanic activity on Venus have erased many of the smaller craters over time.
What is younger on the moon the maria or the craters?
The maria (large, dark, flat plains formed by ancient volcanic activity) on the moon are younger than the craters (impact sites from asteroids or meteoroids). The maria are estimated to be around 3 billion years old, while many of the craters are thought to be upwards of 4 billion years old.

When did Mercury get craters?
Each crater on Mercury was left behind by an asteroid or comet that collided with it. Many of the craters are nearly as old as the planet itself, as collisions were far more common when the solar system was young. Other craters may only be a few million years old.
Why have old craters on the moon not been erased as similar craters on earth have been?
The moon has no atmosphere, liquid water, or plate tectonics and little volcanic activity or bury, erode, and southwester destroy impact craters.
What did the moon look like on 12712?
old, dusty and full of craters

How would you tell that a planet or a moon had no atmosphere just by looking at the surface?
If there are lots of craters, it means there is no significant atmosphere. The reason is that any craters will be eroded eventually, by the presence of an atmosphere.
How does the number of craters on Phobos and Deimos suggest that these moons are very old?
Phobos and Deimos are the two moons of Mars. They are small and shaped irregularly. The surfaces are scarred by many large impact craters. This is why the moons are extremely old.

What is visible on the moon?
There are several lunar features that are visible to the naked eye, and more are visible with even a very small telescope.The craters are probably the most obvious; circular impact craters caused by the collision of some very large asteroids or comets have created circular mountain ranges that are hundreds of miles in diameter. There are craters in craters, craters ON craters, and chains of craters. Because the Moon lacks an atmosphere, there are no erosive forces to break down and hide the craters (as there is here on Earth) and so the only thing wearing away the old craters are ..... new craters!Lunar craters are usually named for astronomers and scientists.The other major features of the Moon are the maria, or seas. Originally believed to be oceans and seas of water by classical observers, we now believe that they were made by lava flows.
Where have meteorites crashed and left craters?
There are hundreds. Probably the most obvious is the Barringer Meteor Crater in Winslow, Arizona, USA, but there are craters all over. Many of them are so old and so enormous that we didn't realize they were ancient craters until we saw satellite photos of them.
