Longitude and timezones
Today in class we talked about longitude and timezones. Longitude is a ngular distance on the earth's surface, measured east or west from the Prime Meridian at Greenwich, England. The prime meridian has a degrees of 0 degrees. Also, we talked about the timezones such as if it were 7:00 am here in bel air it would be 7:00 in china because of the 12 hour difference. The lines of longitude run in a north- south direction and they are the farthest apart from the equator and meet at north poles. They are also known as meridians. I also learned that Eratosthenes made the first world map in 195 BCE.
