Often, waterfalls form as streams flow from soft rock to hard rock. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls
Answer:
B. Geocentric solar system
Explanation:
The scientific community is the one that accepts or dismisses theories. Some theories are accepted, and that is because there are enough evidence that support them, while some theories are dismissed as they have been proven over time that they are not correct.
One of the theories that is outdated and has been dismissed by the scientific community is the theory of the geocentric solar system. This theory has been in place and widely accepted for a very long time, pretty much two millenniums.
This theory was basically suggesting that the Earth is the center of the solar system. The Sun, Moon, all the other planets that were known, as well as the stars, were all orbiting around the Earth. This has been proven as wrong (except that the Moon is orbiting around Earth), and that the theory is far away from the truth, so naturally once there were enough evidence it was dismissed.
