Use the drop-down menus to answer each question. Which scale has 12 levels of intensity? Which scale is most useful for earthqua

Answer:

The positions of the stars and constellations shift each month.

Explanation:

It's important to note that the Earth is in constant motion as it orbits the sun; as a result, certain stars that were previously visible from some locations on Earth may no longer be seen later.

This is why NASA releases a new Star Finder each month to track the movements and changing placements of stars and constellations.
