Answer :
The statement is true; half of the Earth is always lit by the Sun, while the Moon's visible lit portion changes regularly, creating the lunar phases. The Moon's phases occur as it orbits Earth, showing differing amounts of its sunlit half depending on the angle viewed from Earth.
The statement, 'Half of the earth is always lit, but the amount of the moon lit changes throughout the month', is true. This phenomenon is a result of the Moon's phases that occur due to its orbit around the Earth. To understand this, let's picture a scenario where the left part of the moon was lit. As the Moon continues its orbit, we observe the lit part decreasing until the new moon phase, where the entire Moon appears shaded. This sequence reverses as the process starts with a partially lit right side of the moon, increasing until it becomes a full moon. The changes in the lit portion of the Moon are not due to Earth's shadow but are the result of the Moon's own shadow as it revolves around the Earth, with one hemisphere always facing the Sun and being illuminated. The variance in how much of this illuminated part we see from Earth is what causes the phases of the Moon.
In the classroom experiment using a ball to represent the Moon, students could see that regardless of the Moon's position around the Earth, there is always half of the moon being lit by the Sun. However, from our perspective on Earth, we do not always see this fully lit portion. This reflects the concept that the lit shape of the Moon changes in a regular way, from crescent to half to full and so on, over the course of about 29.5 days.
That is True. And did you know we only ever see one side of the moon?
