1. A. Earth rotates on its axis

2. If the earth were closer to the sun, the temperature would be much higher.

Explanation:

As the night passes we can see that there is a certain movement of the stars. Regarding the bear, we can see that it appears in different positions in different perspectives. This happens due to the rotation of the earth in relation to its own axis. The smaller bear is too far from the earth for the proper movement it represents to be perceived, so it is the movement of the earth that provides the displacement sensation of the small bear.

If the earth were closer to the xol, we would see a big change in its temperature. The land would become much hotter, and it may even be impossible to keep bodies of water and living beings on its surface.
