31. What’s the time? Imaginary lines run from the North Pole to the South Pole. These are called lines of longitude. They help us to pinpoint locations on the Earth’s surface as well as to determine the time at any given place on Earth. Imaginary lines run from the North Pole to the South Pole. These are called lines of longitude. They help us to pinpoint locations on the Earth’s surface as well as to determine the time at any given place on Earth. The Greenwich Meridian is found at 0˚ longitude. There are lines 180˚ east and west of the Greenwich Meridian. The Greenwich Meridian is found at 0˚ longitude. There are lines 180˚ east and west of the Greenwich Meridian. 31

32. The time is determined by adding one hour to the time at the Greenwich if you move east and subtracting one hour to the time at the Greenwich if you move west. Eg. 5 o’clock in the afternoon in Cape Town and 12 0’clock midnight in Perth. 32
