Why can’t we see the far side of the moon?
The simple answer is that the moon rotates around its axis in the same time that it takes to revolve around the earth. This phenomenon is called Tidal Locking. Take a piece of stone, tie it to a string and put a colored sticker on one side. Preferably on the side of the string that you are holding. Spin it around yourself. The sticker will always face you. That is almost what is happening in the case of the moon except that it is also rotating around its axis.
How is the dark side of the moon different from the front side?
The two sides of the moon have some stark differences. For starters, the side facing Earth has darker spots. These dark spots are basaltic plains formed due to the rapid cooling of volcanoes. Yes, about 3-4 billion years ago, the moon used to witness volcanic eruptions. These darker areas are called Lunar Maria. Whereas, the far side of the moon has more craters, more towering mountains, and almost no basaltic plains.
