The American Smelt averages 10inches in length, most species are Marine, and the feeding habits are destructive and sometimes cannibalistic.
Answer:
a) there was no evidence to support it
Explanation:
Wegener noticed while looking at the maps that some parts of the continents, especially South America and Africa, seem to match up perfectly. This led him to think that maybe the continents in the past were actually connected, but because of some force they moved apart. He went out public with his hypothesis, but it was largely rejected, and he was laughed at and ridiculed, as the scientists thought that there's no force that can move the continents. Wegener didn't stop there, and he continued to look for clues, and finally managed to find some clues at the topography of the Atlantic Ocean. He noticed that the mid-ocean ridge is the highest, but as you move away from it, the sea mounds are becoming flatter and lower, thus a sign of erosion, and he actually turned out to be right.
After reviewing the graph you posted above, there is one radioactive isotope that has a half life that is approximate to the same as the estimated time of the origin of Earth.
The radioactive isotope is called Uranium 238. You can also write this out as U-238 or uranium/u. Any of these are acceptable for the answer.
