Because the area on Earth that's inside the tip of the moon's shadow is usually only a couple of hundred miles wide at most, and it's moving along the Earth's surface at thousands of miles an hour, and only the people who happen to be inside that little area see the total solar eclipse.
Over a substantial period of time, the numbers of solar and lunar eclipses are equal. For example, during the 100 years of the 20th Century, there were 128 solar eclipses, and 129 lunar ones.
The difference is that during a lunar eclipse, everybody on the night side of Earth can see it, but during a solar one, you have to be in just the right place on the day side.
Another way to look at it: A lunar eclipse happens on the Moon, and anybody who can see the Moon can see the eclipse. But a solar eclipse happens on the Earth, and in order to see it, you have to be where the eclipse is.
The solar eclipse may only be able to be seen in one area, and that is totally normal. Traveling at such a fast speed not many would be able to. So, the velocity and speed it is going at does have a play in this matter ⇒ :)
The Rules of Protein Structure. The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
they compare fossils to other fossils to see if skeleton changes are observed in a species over time it indicates that there is genetic change going on within the species
I just did this BTW. The correct answer is A.) Nuclear fusion is the correct answer. Nuclear fission is what we use today in nuclear power plants, a great deal of radioactive waste, the other are by products of this process. Nuclear fusion releases a great deal of energy with a little radioactivity, but the problem is ignition temperatures; but maybe someday.
