Serious environmental problems. :)
Answer: is constant
Explanation:
In order to analyze the velocity of the stars within a galaxy, the <u>galaxy rotation curves</u> (developed by the American astronomer Vera Rubin) are used. These graphs are elaborated as a scatter diagram in which the orbital velocity of the stars present in a galaxy is represented on the Y axis and the distance of these stars to the center of the galaxy on the X axis.
Thanks to this diagram, it has been possible to observe a characteristic behavior in the rotation speed of the stars (and gas) present in the galaxies, which differs from the rules of the orbital movement of the planetary systems postulated by Newton and Kepler.
This means that in these galaxy rotation curves it has been observed that the rotation speed of stars and gas is "constant", regardless of the distance to the center of the galaxy. This discrepancy and these results were then used to demonstrate the existence of dark matter in the universe.

Answer:
The movement of continents has affected weather patterns by creating mountain ranges and changing the location of the continents.
Explanation:
The movement of continents, or rather the movement of tectonic plates, has had, has, and will continue to have a huge impact on the weather patterns on Earth. One of the things that are among the most influential is the creation of mountain ranges and the changing locations of the continents.
The creation of mountain ranges alters the movement of air masses, meaning that it is a process that influences the amount of precipitation, as well as temperature distribution in the areas where they are found. The changing locations of continents are even more influential. This determines the size of oceans and seas and because of that the ocean currents as well. If there is more landmass around the poles then the climate will be colder and drier on a global level and the sea levels will be lower, but if landmass is lacking around the poles then the global climate will be warmer, wetter, and the sea levels will be higher.
