Time Zones

The World in Spatial Terms7.3.1 Formulate a broad understanding of the location of countries of Africa, Asia and the Southwest Pacific7.3.2 Formulate a broad understanding of the location of capital cities in Africa, Asia and the Southwest Pacific using latitude and longitude on maps and with locational technology such as Global Positioning Systems and Geographic Information Systems.

How to Calculate Distance and Time in Time Zones

There are 24 standard time zones in the world

For each 1 hour of time, you travel 15 degrees of longitude:

There are 360 degrees in a circle-divided by 15 degrees for each hour traveled= 24 standard time zones

East to West / West to EastWhen traveling from the east to west you

subtract 1 hour for each time zone

When traveling from west to east you add 1 hour for each time zone

Time zones are counted from the Prime Meridian which runs through

Greenwich, England

The International Dateline

The International Dateline is the place where the days change. It follows closely to the 180 degree meridian.

Sorry---- this isn’t a place to get dates from people in foreign countries!!!

Why doesn’t the International Dateline run through any land?

The Earth Spinning on its Axis

• The earth is spinning at about 1038 miles per hour at the equator, and about 0 at the poles. It would be somewhere around 700 mph in Indianapolis!

The earth travels through space at about 67,062 miles per hour
