Why don't the craters on the moon eventually erode away?
They do, but very slowly. There is no atmosphere or liquid water on the Moon, meaning no wind, waves, or blowing dust to erode the craters. There is also no volcanic activity or tectonic action to erase them as on Earth. Many more craters have been obliterated by subsequent impacts than by slowly crumbling away. Some craters are hundreds of millions of years old.
Why can you still see craters on the moon even though they were formed by ancient meteor collisions?
You can still see craters on the moon because there is no atmosphere to erode them away like on Earth. Since the moon lacks geological processes like weathering and plate tectonics, impacts from meteoroids have not been erased over time.
Why do craters last for millions of years on the moon?
Craters last for millions of years on the Moon because there is no atmosphere to erode them. On Earth, weathering processes like wind and water can slowly wear away craters, but on the Moon, the lack of atmosphere means that craters remain relatively unchanged for long periods of time. Additionally, the Moon's surface experiences very slow geological processes, further preserving these features.
What are the processes that erase impact craters on the Earth over time?
Some processes that erase impact craters on Earth over time include erosion by wind, water, and ice, as well as geological processes like tectonic activity and volcanic activity. Weathering can also gradually wear down the edges of craters, and sedimentation can slowly fill them in. Additionally, the Earth's crust is constantly shifting and recycling, which can also contribute to the disappearance of impact craters.
Why aren't impact craters eroded in the moon?
Impact craters on the Moon are not eroded as quickly as on Earth because the Moon lacks an atmosphere and active geological processes. Without wind, water, or vegetation to wear down the craters, they can remain well-preserved for millions of years. Additionally, the lack of tectonic activity means there are no plate movements to alter the landscape.
What is the process on earth that has wiped away evidence of impact craters?
Erosion is responsible for the gradual wearing away of the evidence of impact craters. Wind is able to carry small particles that can slowly chafe and wear away the jagged and steep slopes, while water likewise can carry soil away. Both of these processes smooth the edges of an impact crater. Given enough time, the crater's edges could be sanded down by erosion to the point that a crater looks no different from any other valley.

How do craters change over time?
Craters can change over time due to factors such as erosion, weathering, impacts from other celestial bodies, and tectonic activity. Erosion can wear down the edges of the crater, weathering can alter its appearance, impacts can create new craters or modify existing ones, and tectonic activity can cause the land to shift, changing the crater's shape.

Does erosion wear away rock and makes them square?
No. Although the movement of rocks may assist in their reduction in size, the weathering that occurs will tend to produce rounded edges.
How you inflate impala tires 2007?
Go on the high side, they wear the edges real bad. Go on the high side, they wear the edges real bad.
Why do diamonds have no wear to facet edges?
Diamond is the hardest natural mineral known. Wear could show on the edges if the diamond rubbed against another diamond.
Why do some planets have more meteorite craters than others?
The planets with more craters are the ones with less geologic activity. Geologic activity such as erosion, plate tectonics, and volcanic eruptions will wear down, bury, or otherwise destroy impact craters. If there is no geologic activity, then there is nothing to disturb the craters other than later impacts from comets and asteroids.
Which parts wear away first in shoes?
The parts of shoes that typically wear away first are the soles, particularly the heel and toe areas. This wear occurs due to the constant friction and pressure they experience during walking or running. Additionally, the outer edges of the sole may also show signs of wear, especially for those who pronate or supinate while walking. The upper material can also wear out, but it generally lasts longer than the soles.
Why do you have to wear spacesuits?
No oxygen in space. We need oxygen.
