Give three importances of the International Date Line
Answers
Answer:
The International Date Line (IDL) is an imaginary line of demarcation on the surface of Earth that runs from the North Pole to the South Pole and demarcates the change of one calendar day to the next. It passes through the middle of the Pacific Ocean, roughly following the 180° line of longitude but deviating to pass around some territories and island groups.In order to enable us to calculate the distance between one place to another, a number of circles are drawn round the globe. Every circle is divided in to 360 degrees and each degree is approximately 69.5 miles. Lines of latitude and longitude enable us to measure distances on the map, or to find the position of any place on the map.
Latitude is distance, measured in degrees, north or south of the equator. Longitude is the distance, measured in degrees, east or west of a given Meridian. Meridian s or mid-day lines are lines drawn on the map from the North Pole to the South Pole, and all places on any of these lines have the mid-day at the same time. The prime Meridian passes through Greenwich, which is it is considered as the standard.
the world spins in a circle and every time it spins in a complete circle it becomes a new day. the international dateline is where we start measuring and when the world goes all the way around and back to that line, it is a new day.
