Respuesta :
The answer to this question would be: A.The moon both rotates on its axis and revolves around Earth every 28 days.
The moon rotates and revolves in the same rate of 28 days. That means the side that we can see from earth would be same all around the year. That also goes to the side which we can't see, and that side is called "dark side of the moon" because we can't see it.
The moon rotates and revolves in the same rate of 28 days. That means the side that we can see from earth would be same all around the year. That also goes to the side which we can't see, and that side is called "dark side of the moon" because we can't see it.
The rate of rotation and revolution of the moon remains the same in every 28 days. This means that the side one can see from the Earth would always remain the same throughout the year. Therefore, the side which not visible by us is called the 'dark side of the moon'.
Further Explanation:
The only natural satellite that revolves around the Earth is the moon. The moon shines as it reflects light coming from the Sun. The portion of the moon visible to us keep on changing in the cycle that repeats every 28 days or a month. This is due to the positions of the Earth, Moon, and Sun relative to each other. When the moon moves around the Earth, its side facing towards the Sun is always enlightened similar to the illumination of the daylight side of the Earth by the Sun. When seeing from the Earth, a dark new moon starts with a visible light part of the Moon which grows to form a silver curve to half-moon which finally grows into a full moon. This is followed by a decrease in illumination which causes the moon to become thinner to invisible in the sky. This brings back the new moon cycle again.
A new moon is achieved when the moon’s orbit moves the moon between the Sun and the Earth. As we see from the Earth, the surface of the moon appears darker as the side which is illuminating is facing the opposite. As moon orbits in a counter-clockwise manner, the illuminated part of the moon becomes more and more visible and finally reaches a full moon stage. This stage results when the position of Earth is in between the Sun and the Moon.
The rotation of the moon occurs on its own axis and it also experiences dark and daylight cycles. Every 28 days, the spinning of the moon occurs on its axis. The moon's revolution time around the Earth is the same as its rotation period. This implies that the time required by the moon to revolve around the Earth and also to turn on its axis is the same. Therefore, one will always observe the same side of the moon. The other side which we never are called the far-side or the dark side of the moon.
