Detailed explanation-1: -Lines of latitude, also called parallels, are imaginary lines that divide the Earth. They run east to west, but measure your distance north or south.

Detailed explanation-2: -The spinning of the earth on its axis from west to east provides two natural points of reference, i.e. North and South Poles. They form the basis for the geographical grid. A network of intersecting lines is drawn for the purpose of fixing the locations of different features.

Detailed explanation-3: -All latitudes are angular distances measured towards the pole from equator. All longitudes do not join poles. All parallels and Meridians are imaginary lines. Latitudes are used to determine the time of a place.

Detailed explanation-4: -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.

Detailed explanation-5: -Longitude is the measurement east or west of the prime meridian. 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.
