Longitude and time zones
I can identify the Prime Meridian and understand time zones.
Lesson details
Key learning points
- Time zones to the east of the Prime Meridian are ‘UTC (or GMT) plus’; time zones to the west are ‘minus UTC (or GMT)'.
- Webcams are a useful source of information about what is happening in places which are in different time zones.
- Earth is divided into 24 standard meridians, at intervals of 15˚, which are the basis for delineating 24 time zones.
- Time zones are measured from the Prime Meridian at 0˚ longitude, where the time is Universal Co-ordinated Time (UTC).
Common misconception
UTC and GMT are the same.
UTC is a time standard - an agreement to synchronise the worlds timings centres to this standard time. GMT is a time zone.
