Question.
Why do we see only one side of the moon always?
( Chapter 1: The Earth in the Solar System, Class 6- The Earth: Our Habitat ( GEOGRAPHY), SOCIAL SCIENCE)
Answer.
Moon is only one satellite of our earth. The diameter of the moon is one-fourth of Earth. The phenomenon of always seeing only one side of the Moon from Earth is known as "tidal locking" or "synchronous rotation." It occurs because the Moon's rotation period (the time it takes to complete one rotation on its axis) is nearly equal to its orbital period (the time it takes to orbit Earth).
About Synchronous Rotation:
The Moon takes about 27.3 days to orbit Earth, and it takes roughly the same amount of time to complete one full rotation on its axis. As a result, the same side of the Moon always faces the Earth. This synchronous rotation is due to gravitational interactions between the Earth and the Moon.
In this state, one hemisphere of the Moon is permanently facing the Earth (the near side), while the other hemisphere (the far side) remains hidden from our view. The other side of the moon is called the dark side of the moon because it hides from Earth.
In summary, the phenomenon of seeing only one side of the Moon always is a result of the Moon's synchronous rotation, caused by gravitational interactions and tidal forces between the Earth and the Moon.
