Detailed explanation-1: -Lines of longitude, also called meridians, are imaginary lines that divide the Earth. They run north to south from pole to pole, but they measure the distance east or west. The prime meridian, which runs through Greenwich, England, has a longitude of 0 degrees.

Detailed explanation-2: -Longitude is measured by imaginary lines that run around Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arc degree of longitude. The distance around Earth measures 360 degrees.

Detailed explanation-3: -The line of longitude where the degree is zero is known as the Prime Meridian. Passing through the Royal Observatory, Greenwich, England, it is also known as the Greenwich Meridian and divides Earth into two equal halves known as the Eastern Hemisphere and the Western Hemisphere.

Detailed explanation-4: -Latitudes are horizontal lines that measure distance north or south of the equator. Longitudes are vertical lines that measure east or west of the meridian in Greenwich, England.

Detailed explanation-5: -India is a vast country. Lying entirely in the Northern hemisphere (Figure 1.1) the main land extends between latitudes 8°4’N and 37°6’N and longitudes 68°7’E and 97°25’E.
