Standard Time and Its Necessity Now for each city or a place to keep individual time based on its longitudinal position would complicate matters, especially in cases of medium to big countries. Since for each degree change in longitude, there is a time difference of four minutes, people travelling from one part to other part […]

Latitude and longitude form Earth’s coordinate system for precise location mapping. Latitudes are horizontal circles (0° to 90° N/S) measuring distance from the Equator. Longitudes are vertical semicircles (0° to 180° E/W) measuring distance from the Prime Meridian at Greenwich. Key parallels include Equator (0°), Tropic of Cancer (23½°N), Tropic of Capricorn (23½°S), Arctic Circle (66½°N), and Antarctic Circle (66½°S). Every 15° longitude equals one hour time difference, making them essential for navigation, climate zones, and timekeeping worldwide.

The Earth is spherical in shape; it is an established fact, backed by several pieces of evidence. The equatorial circumference of the Earth is 24,897 miles, while its polar circumference is less than 83 miles than that of the equatorial circumference. This shows the Earth is not a perfect sphere. The Earth is flattened at

Unlike traditional comets, these bodies lack the bright tails and icy nuclei commonly associated with their bright counterparts, making them resemble asteroids. Their elusive nature has intrigued scientists and led to significant discoveries over recent years. Discovery and
