Explaining the Concept of Solar Time. Most large countries that span a range of longitudes (e.g., USA, Canada, Russia) have multiple time zones. This ensures that civil time isn’t too far from the local solar time.

WebLatitude and Longitude lines are a grid map system too. But instead of being straight lines on a flat surface, Lat/Long lines encircle the Earth, either as horizontal circles or vertical half circles. Horizontal mapping lines on Earth are lines of latitude.
