Our telescopes show the moon to be a very mountainous world, with several great mountain ranges and an immense number of mountains in the form of a ring or craters. There are no oceans or lakes. If there were patches of water on the moon we should at times get strong reflections from them, making them appear intensely bright just as we do when we see the sun low over the sea.
The moon. in common with other planets and satellites of the dem, does not shine any it because it reflections the light ot its own. We see sun and the moon cease light the sun that on il. Blou out the phases. any time half to rom a shows If of shine. It is because of this that the moon darkness. we are facing its surface is sunlight, the other half is in are facing toward the su in we side we say it is full moon; if The dark side we say it is new moon The moon is therefore a dry world. If there were water on the moon we should expect to see clouds, but no cloud ever appears over its surface. Not only is the moon a world without water, it is also a world without any atmosphere at all; there is breeze: no sound to break the silence; no air: no no water; no life, either animal life or plant life.
The moon is much smaller than the earth, having a diameter of about 2000 miles. It weighs very much less than the earth: actually its weight is about one-eightieth of that of the earth he moon's gravitational pull is herefore not very great The first landing on the moon on July 21, 1969 proved that conditions on the moon are extremely unpleasant. During the long lunar day, which is bout 14 times of ours, the sun strikes down from a cloudless equal to sky. At noon the temperature is well above the boiling point of water of course, it would not be possible for human beings to survive in such great heat. As soon as noon has passed the temperature begins to fall for there is no water vapor to act as a blanket to prevent the heat from escaping, Toward evening the fall of temperature is very rapid and by sunset it is freezing hard It had been believed until the landing on the moon that if we had been able to be on the moon, we would have been soon shot by a shooting star. Scientists and astronomers used to believe that a great number of fragments or shooting stars fell to the surface of the moon almost all the time, Now we know, having seen the landing on the moon through television, that an astronaut can walk for some time on the surface of the moon safely from such fragments
