Which meridian lies opposite on globe?
The International Date Line is an imaginary line on the surface of the Earth that sits mostly on the 180º line of longitude in the middle of the Pacific Ocean. The International Date Line lies on the opposite side of the world to the Prime Meridian (The Prime Meridian passes through Greenwich in London.
Why Greenwich is the prime meridian?
There were two main reasons for the choice. The first was the fact that the USA had already chosen Greenwich as the basis for its own national time zone system. The second was that in the late 19th century, 72% of the world’s commerce depended on sea-charts which used Greenwich as the Prime Meridian.

Where is the exact place on Earth?
To help us locate places on the earth’s surface, we use a coordinate system. This coordinate system is like placing a giant grid over the earth. This grid has lines extending from east to west called lines of latitude and lines extending from north to south called lines of longitude.
What are 3 facts about meridians?

Null Island
Null Island is the point on the Earth’s surface at zero degrees latitude and zero degrees longitude ( 0°N 0°E), i.e., where the prime meridian and the equator intersect. Null Island is located in international waters in the Atlantic Ocean, roughly 600 km off the coast of West Africa, in the Gulf of Guinea.

antipode
Geography. The antipode of any place on the Earth is the place that is diametrically opposite it, so a line drawn from the one to the other passes through the centre of Earth and forms a true diameter. For example, the antipodes of New Zealand’s lower North Island lie in Spain.

How do you explain the prime meridian to a child?
The prime meridian is the imaginary line that divides Earth into two equal parts: the Eastern Hemisphere and the Western Hemisphere. The prime meridian is also used as the basis for the world’s time zones. The prime meridian appears on maps and globes. It is the starting point for the measuring system called longitude.
What is the difference between Greenwich Meridian and prime meridian?
Greenwich meridian, also called prime meridian, an imaginary line, last established in 1851, that was used to indicate 0° longitude. It passes through Greenwich, a borough of London, and terminates at the North and South poles. Because it indicated 0° longitude, it was also known as the prime meridian.
