While persisting on the North Pole, you can ideally recognize the whole circle of the globe. This is why it begins at zero and finishes at longitudes.
Each meridian measures one arcdegree of longitude. The distance around the Earth measures degrees. The meridian that runs through Greenwich, England, is internationally accepted as the line of 0 degrees longitude, or prime meridian. The antimeridian is halfway around the world, at degrees. The time of a place depends on the longitude that passes through it. Therefore, the standard time for each country is usually taken as the time of the central meridian that passes through it.
Thus, we need a standard meridian for the country. The local time stated or mentioned at this meridian is considered as the standard time for the whole country. Was this answer helpful? Standard meridian is useful for a country because it shows and fixes a particular time for the country. A country may have many longitudes in between and there is a time gap of 4 minutes between each longitude.

Moreover, the Equator divides the Earth into Northern hemisphere and Southern hemisphere. As you can see from the above image, Earth is widest at its Equator. In fact, the distance around the Earth at the Equator, i. Moreover, at the Equator, the day and night have the same length around the year. Unlike the countries around the Northern and Southern hemisphere, countries around the Equator do not experience four seasons.
Equatorial regions regions near the Equator typically have two seasons: dry season and wet season. In addition to that, their climate is very humid. Some of the most extensive rainforests in the world are in equatorial regions: the Amazon rainforest, the Congo rainforest of Central Africa, the Harpan rainforest, the Daintree Rainforest, etc.
On the other hand, what is on the western side of your house will become part of the western hemisphere. However, in the current world scenario, the line of longitude that passes through Greenwich London is taken as the central longitudinal reference point. To know more: What is Prime Meridian? Out of all the lines of longitudes, the Greenwich Prime Meridian line is the most important one. Just to let you know, in total, there are lines of longitudes. The Greenwich meridian line is the most important line of longitude because:.

Hey man, If you have come this far, do give us feedback in the comment section. It would make my day. I am a mechanical engineer by profession. Just because of my love for fundamental physics, I switched my career, and therefore I did my postgraduate degree in physics.
Right now I am a loner as ever and a Physics blogger too. My sole future goal is to do a Ph. Because in my view, every aspect of physics comes within the range of cosmology. And I love traveling, especially the Sole one.
