That would probably impact negatively because just with us people living on land we pollute the bodies of water near us ... so if we started living on water that wouldn't make it any better
Answer:
perimeter/drainage divide
Explanation:
The drainage basin of a stream represent an area of land from which the water is flowing toward the stream. This area has its own natural boundaries, which are usually highlands that alleviate themselves from the three sides relative to the stream which is located in the lowest part of the area.
The boundaries are represented with highland usually, as mentioned, running along ridges, mountains or hills. The water that falls into the naturally enclosed area all flows down toward a single stream directly, or to several streams, and than into the largest, central stream in the drainage basin.
Some of the drainage basins are very small, only occupying few square km, while some are enormous are larger that the majority of the countries in the world.
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.
