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 moon have many craters left?
Crater numbers on the moon can only get bigger cause there is no wind, rain, or volcanic activity to erase the craters. Landslides are rare too.
Why do craters last a million years on the moon?
They last much longer than that. Some of the moon's craters are billions of years old. They last so long because there is nothing to erase them. Earth has wind, water glaciers, volcanoes, and tectonic plates to bury, erode, and erase craters. The moon has none of these processes. Some refer to the moon as geologically dead.
Why does earth have so few visible craters?
Earth is a 'living' planet; its surface is always being changed by the processes of erosion and geological action. Those craters that still remain are either too big to be noticed specifically as craters without the right perspective or, as noted in the question, so few in number that they are a major rarity.
What is the difference between backspace and delete key?
The delete key removes the character above or to the right of the cursor. The backspace removes the character to the left of the cursor.
How do you get your cursor normal?
When you get your computer your cursor should be normal but if its not its not right. [Ej Chapman wrote this answer.]
WHAT keys move the curser left and right?
The arrow keys on the keyboard typically move the cursor left and right. Pressing the left arrow key moves the cursor left, while pressing the right arrow key moves the cursor right.
When typing a documentto remove a character on the right of the cursor you would?
Press the Delete key to remove a character on the right of the cursor.
Why don't the craters on the moon weather away as they do on earth?
The answer is actually embedded in the question. The craters of the moon do not "weather" away because the Moon has no weather! To have weather requires an atmosphere and the Moon has none. There is also no free flowing water. Without tectonic and volcanic activity to erase craters as occurs on Earth, craters can persist for up to hundreds of millions of years.
Why don't craters erode on the moon?
They do, but extremely slowly. There is no atmosphere or liquid water on the Moon, meaning no wind, rivers, 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, and have many smaller craters within them.
Why have very old craters on the moon not been erased as similar craters on earth have been?
Many places on the moon suffer from a shortage of the things that erase craters on the earth, including air, wind, water, rain, storms, lightning, mud, burrowing animals, tides, roots of growing plants, earthworms, etc.
How can you erase a creation on Aviary?
Ok found it... go to "your creations," then on the right there's an option to erase
