How Many Time Zones Are There on Earth?

Answer

The earth rotates every 24 hours which is why we have 24 hours in a day. We also have 24 time zones, each time zone stands for one hour. There are 360 degrees in a circle so it is 360 degrees around the earth. If we chopped the earth into hunks of 24, since there are 24 hours in a day, we would end up with each chunk being 15 degrees. Each time zone is 15 degrees wide at the equator. Time zones help us tell time. Humans designed time zones to help tell time. The rotation of the earth tells us if it is day or night. We decided to have time zones to make it easier.The rotation of the earth has an effect on how many time zones we have.
