The moon is our nearest neighbor in space. The moon is a lifeless place. It has no air or water. Its surface is covered with rocks and dust. There are tall mountains and flat plains on the moon. There are also large round ditches called craters. Some of the craters are hundreds kilometers wide. Many of them have been made by large rocks fallings on the surface of the moon. If you look at the moon on full moon night, you can see light and dark areas. The dark areas are plains and the light ones are mountains. Craters of moon can be easily seen with a telescope.
Those of you who live in cities near the sea such as Karachi will know that tides are. A tide is a regular rise and fall of water in a sea or oceans. It occurs approximately every 12 hours. During high tide the water level rises. During low tide it goes down. Tides occur mainly because of the gravity of the moon. The gravity of the sun also affects the tides. Burt since the sun is very far off, it has very little effect.
