ANSWER THE 4 QUESTIONS FOR BRAINLIEST AND 10 POINTS

1. The sun's position changes,because the Earth turns on its axis,which causes the sunlight to hit at different angles. This  means that after a period of time,the sun no longer shines on one side. It will be dark/night on one side and light/day on the other side.

2.Shadows change,because the angle that the light hits us is different overtime.

3.The flagpole will look the same from when it started at the exact time.

4.Overtime our shadows become small and you may not be able to see it. That is mostly for small objects.You can see the but for small and certain angles.
