The reason is that as Earth travels round the Sun in 12 months, the stars that are visible at midnight each night shift slowly by about 1 degree every 24 hours so that a complete circle round the sky is completed once a year.
In the opposite direction is the Sun, and the Sun moves across the background of stars also competing a circle every year. In the summer the Sun is approximately lined up with Orion so that the stars of Orion can't be seen because of the glare from the Sun. Actually, Orion is visible in the summer sky, to the east just before sunrise in the Northern Hemisphere.
From the viewpoint of the Earth, all the constellations 'revolve' around Polaris (the North star. As the Earth orbits the sun, its relative position to the constellations changes - and they appear to move across the night-sky.

The stars comprising Cassiopeia are in the same positions (with minute shifts unnoticeable without advanced telescopes and measuring equipment) now as they have been for thousands of years- If someone decides to redraw the borders they can do that whenever they want but it will not affect the position of the stars.
Seasons changing throughout the year is an example of a predictable change. This cycle occurs regularly and follows a set pattern based on the Earth's position in relation to the sun.
Mercury changes position the most with respect to the sun. It has the shortest orbital period of any planet in our solar system, so it completes its journey around the sun faster than any other planet. This causes it to appear to change position relative to the sun more frequently.
It is evidence that the earth orbits around the sun.
Constellation change position during the night due to the earth's multiple motions, such as the wobble and rotations around the sun.

On a daily basis, the rotation of the Earth. On a seasonal basis, the motion of the Earth around the sun. Over the long term ... they're all independently moving around the center of the galaxy.
The Big Dipper appears to rotate around the North Star throughout the night due to Earth's rotation. Its position also changes throughout the year as Earth moves in its orbit, causing the constellation to rise and set at different times. These changes make the Big Dipper appear to shift in the sky, but its overall shape remains relatively constant.
This is a result of the earth's orbiting the sun. We are looking at the constellation from a different angle as the weeks progress.
The position of Orion seems to change through the sky because stars moved just like planets. But, if you sand there and just stare at it all night you cannot sense its motion. You could probably see it over a few days. The movement of stars is so hard to detect from earthi because they are so far away from us
Shadows change because the position and angle of light sources change throughout the day. As the sun moves across the sky, shadows shift in direction, length, and intensity. Additionally, factors like cloud cover and the position of objects can also affect how shadows appear.
As the Earth goes around the sun, it changes its position relative to the stars in those constellations. At times, some stars won't be visible as they will be behind the sun. This change in perspective isn't enough to make it appear as if they stars have taken a radically new position. They still seem to be just where they always have been. That's why the stars of each constellation stay in the shape of the constellation and instead it seems as though the whole constellation moves. Really, it's just us that are moving.
Yes, the position of the Big Dipper will change over two hours as the Earth rotates. The Big Dipper will appear to move across the night sky due to the Earth's rotation, so its position will shift throughout the night.
Only if you look at it at the same time every night. If you look at it 4 minutes earlier each night, then it doesn't change position at all.
Type your answer here... Because the Earth is rotating on its axis. As the world turns throughout the day, the Sun "appears" to change position from East to West. But actually, it is Earth that is rotating. It it is like driving in a car. When you see a sign coming up, it looks like it is getting closer and then it goes by you. The sign was not moving. You were in a car that was moving.
