Why does the sunset appear to move?
why is phase not a good way to classify matter?
Alex, the earth is rotating, so — in relation to this — the the sun appears to be setting.
I don't know if this is what you are looking for, but I hope it helps. Thanks for asking.
First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where is more likely to be overlooked.
Since this is not my area of expertise, I searched Google under the key words "classify matter phase" to get these possible sources:

It seems like the same matter (e.g., water) can exist in all three phases, depending on the temperature. Use your <Find> to search for "phase" within the above sites.
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
The sunset appears to move because of an optical illusion known as the "Earth's Rotation". The Earth spins on its axis, completing one full rotation every 24 hours. As the Earth rotates, different parts of the planet are exposed to the Sun's light, creating the perception of the Sun moving across the sky.
To understand why the sunset appears to move, we need to understand the concept of "apparent motion". Apparent motion refers to the perceived movement of an object due to the relative motion between the observer and the object.
In the case of the sunset, when the Sun is close to the horizon, the Earth's rotation causes the Sun to gradually disappear from view. As the Earth rotates, the observer on the surface moves away from the direct sunlight, causing the Sun to appear lower in the sky until it eventually sets below the horizon. This gradual descent of the Sun creates the perception of its movement across the sky and the phenomenon we know as the sunset.
It's important to note that the Sun does not actually move, but rather, it is our movement as Earth's inhabitants that gives the illusion of the Sun's motion. The Earth's rotation is also responsible for the sunrise, as it brings the Sun back into view in the morning.
So, the apparent movement of the sunset is an optical illusion caused by the Earth's rotation, and understanding this concept helps us appreciate the dynamics of our solar system.
