There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western.Students look at lines of latitude and longitude on United States and world maps, discuss why these lines are helpful, and identify landmarks with similar latitude and longitude. Longitude is the measurement east or west of the prime meridian.Encyclopedic entry. Therefore, the standard time for each country is usually taken as the time of the central meridian that passes through it. Dunn, Margery G. (Editor). The time kept at any place is denoted with reference to time at prime meridian (GMT or UT). Standard time is the synchronization of clocks within a geographical area or region to a single time standard, rather than using solar time or a locally chosen meridian (longitude) to establish a local mean time standard.

Any circle drawn around the Earth divides it into two equal halves called hemispheres.

India has a vast longitudinal extent. It runs through the center of the country. East of this line is one day earlier than west.

All meridian east of prime meridian is called east longitude and west is called west longitude. Since many meridians pass through it, it is important to adopt the local time of one central meridian of a country as the standard time for the country. Caryl-Sue, National Geographic Society The significance of standard meridian of India is that Standard meridian is used as the standard time for whole country.

Longitude of prime meridian is 0. According to the International accepted convention, the Standard Meridian of a country must be either a multiple of 7.5 or 15 or it has to pass through some important city.

They chose the meridian passing through the Royal Observatory in Greenwich, England. Finally, at an international convention called by U.S. President Chester Arthur in 1884, representatives from 25 countries agreed to pick a single, standard meridian. Nancy Wynne Longitude is the measurement east or west of the prime meridian.Encyclopedic entry.

This is known as the (1829-1886) 21st president of the United States (1881-1885).formal meeting, usually with representatives from different regions or parties.time standard based on atomic time that is coordinated with rotational timethe cycles of day and nightby the introduction of leap seconds at certain intervals.

Generally, standard time agrees with the local mean time at some meridian that passes through the region, often near the center of the region.

The concept was adopted in the late 19th century in an attempt to end the confusion that was caused by each community’s use of its own solar time.

Thus, we need a standard meridian for the country.

Since many meridians pass through it, it is important to adopt the local time of one central meridian of a country as the standard time for the country.

The prime meridian is arbitrary, meaning it could be chosen to be anywhere.The prime meridian and the International Date Line create a circle that divides the Earth into the eastern and western hemispheres. There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western.Students look at lines of latitude and longitude on United States and world maps, discuss why these lines are helpful, and identify landmarks with similar latitude and longitude.Encyclopedic entry. Thus, we need a standard meridian for the country. The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around the Earth. Please log in again!
