Then the water comes back together where the droplet hits and there is a brief peak where the droplet was. The same thing has happened on the surface of the moon to create these peaks. There are also mountian ranges on the moon that are not peaks of craters. Craters can then be subclassified into rayed or non-rayed. Rayed craters are caused when something strikes the surface of the moon at an angle so that the rock and dust that used to be where the crater is gets thrown in all directions.
Rayed craters look like there are streaks around it.
Some of these craters have the rays all around them and some only have them on one side. Any time you are not looking at a full moon or a new moon, you will have an area on the lunar surface called the terminator . This is the line of sunrise on the moon where the illuminated part of the moon meets the shadowed part. This is an interesting area to look at through a telescope because the shadows are long here and the features really stand out. Notice that south is at the top of the map and east is to the left.
