Test: Map Lines - UPSC MCQ

Map Lines are lines connecting points on a map that share a common geographical or atmospheric property. Lines of the same latitude run parallel to the Equator, while lines of the same longitude run from pole to pole.

Isobars are lines on a weather map connecting places with equal atmospheric pressure. They help in identifying areas of high and low pressure systems.

The International Date Line is mostly situated along the 180 degrees longitude. It is the line that separates two consecutive calendar days.

The Prime Meridian, representing 0 degrees longitude, passes through Greenwich, London, United Kingdom.

The Antarctic Circle is a map line located at approximately 66.5 degrees South latitude, marking the region around the South Pole where for at least one day a year, there is continuous darkness or continuous daylight.

The Equator is the line of 0 degrees latitude, dividing the Earth into the Northern and Southern Hemispheres.

An Agonic line is a map line that connects points with zero magnetic declination, indicating the direction of true north.

The Antarctic Circle is the map line at approximately 66.5 degrees South latitude, marking the region around the Antarctic where for at least one day a year, there is continuous darkness or continuous daylight.

The Orthodrome is a great circle on the Earth's surface passing through two given points, representing the shortest distance between those points.
