If mercury had a heavy atmosphere would there be more or fewer craters on its surface why?
There would be fewer. This is not because, as is widely believed, the atmosphere acts as a shield. While an atmosphere will cause smaller objects to break up, it will not hinder the larger objects that leave craters that are plainly visible from space. However, action from an atmosphere can erode craters and bury them under sediment.
What else can I help you with?
How do you use crater counts to determine the age of surfaces?
The more craters, the older the surface. If a surface is young, there will be fewer craters.
Why are more craters present on the moons surface than on earths?
The moon has more visible craters on its surface compared to Earth because it lacks an atmosphere to protect it from impacting objects. Earth's atmosphere burns up most small asteroids and meteoroids before they can reach the surface, resulting in fewer visible impact craters. Additionally, the moon's lack of geological activity means that its craters remain preserved over time.
Do all planets have craters in them?
No, not all planets have craters. Craters are often found on solid bodies with little to no atmosphere, like the Moon and Mercury. Planets with active geology or thick atmospheres, like Earth and Venus, may have fewer visible craters due to ongoing processes that can erase them.
Why does earth have fewer impact craters than the moon?
The earth has atmosphere and liquid water, whereas Mercury has neither. Their presence works against the appearance of impact craters in at least two ways: 1). The vast majority of material objects on a course to strike the earth burn up in the atmosphere and never reach the surface. Those that are large enough to survive the entry are reduced in size, mass, and speed before impact. 2). The marks left by impacts that do occur become worn down or "weathered" by the effects of both the atmosphere and the water on earth.
Does the moon have more craters than earth?
Yes, the moon has more craters than Earth. This is because the moon lacks an atmosphere to protect its surface from impacting rocks and debris, whereas Earth's atmosphere helps to burn up most objects before they reach the surface.
Why do you think earths surface has fewer craters than the surface than moon does?
Basically, the atmosphere protects the earth to a great degree and the geological process always going on in and on the earth cover and change many crater sites.
What statement best explains why the moon has more craters than earth?
The moon has more craters than Earth primarily because it lacks a significant atmosphere, which means there is no weathering or erosion to diminish the visibility of impact sites. Additionally, the moon has no active geological processes, like plate tectonics or volcanic activity, that could reshape its surface and erase craters over time. In contrast, Earth's atmosphere, water, and geological activity continuously alter its surface, leading to fewer visible craters.
Does the planet Venus' have craters?
Venus has about 1,000 young craters, the biggest of which is Crater Mead, about 170 mile across. Oddly, there is no evidence on Venus of old craters like we see on the moon, Earth, and Mars. Somehow these old craters were smoothed over on Venus . . . by lava flow?? By high winds??
Why are there more and larger creaters on the surface of the moon than the earth?
Erosion. The earth has suffered its share of impacts, but the eroding effects of wind and water have weathered away all but the biggest or most recent craters. The moon has no atmosphere or water so the impacts there are preserved.
Why does the moon have more crators than the earth?
because earth has an atmosphere which makes asteroids burn up before they hit the ground but the moon has no atmosphere so it can't stop asteroids. also, the moon shields the earth from some asteroids.
Why do you not see evidence of heavy meteoroid bombardment on the moon?
The lack of a significant atmosphere on the moon means that meteoroids don't burn up the way they do in Earth's atmosphere, resulting in fewer visible impact craters being created. Additionally, the moon's surface is constantly being resurfaced by volcanic activity and micrometeorite impacts, which erases evidence of earlier impacts over time.
Will a planet with active volcanoes have more or fewer craters than a planet without active volcanoes?
A planet with active volcanoes will have fewer craters, as older craters will tend to be buried by lava and ash.
