Both the equator and prime meridian are halfway points across the Earth. The equator splits the Earth's Northern and Southern Hemispheres horizontally (latitude). The prime meridian splits the Earth's Eastern and Western Hemispheres vertically (longitude).
You can define any point on the surface of the Earth by measuring degrees, minutes of arc and seconds, north or south of the equator and degrees, minutes and seconds east or west of the Prime Meridian. The equator is the zero mark for latitude; the prime meridian (which passes through the Royal Observatory in Greenwich, England) is the zero point for longitude.
it runs vertical to the equator. It, like the equator, is located at 0 degrees.( it is just like the equator, but it runs vertical right in the center) .. it's origin point is recognized as the Royal Observatory in Greenwich (London) England - it runs south from the there through Europe western Africa.
Allof the lines are calle longitude. Bit the middle one would be the Prime Meridian, as the Equator is the middle like for lattitude.
The Prime Meridian passes through France, so France is on both sides of it.Even if the Prime Meridian does not pass through a country, like the USA for example,the Earth is spherical (shaped like a ball), so you can leave the Prime Meridian inany direction you want to, and wind up anywhere you want to.
Lines of latitude are imaginery lines that run around the earth parallel to the equator and tell you how many degrees north or south of the equator you are. The equator being zero degrees, the North Pole being 90 degrees North Latitude, the South Pole being 90 degrees South Latitude. Lines of longitude are imaginery lines that run from the north pole to the south pole and tell you how many degrees east or west of the Prime Meridian you are. The Prime Meridian is based on Greenwich, England. An easy way to rember is that the latitude lines are like the steps on a ladder, and the longitude lines are very long.
The Earth is roughly spherical (shaped like a ball), so you can start out in either direction from the Prime Meridian and eventually be in China ... that was sort of the whole idea behind Columbus' voyage. But you'll still have a shorter trip if you head out toward the east.
Because it's not based on any physical characteristic of the Earth ... like the Equator is ... but instead, was made up by people and could have been placed anywhere.
East of the Prime Meridian is the Eastern Hemisphere, which includes continents like Europe, Africa, and Asia. West of the Prime Meridian is the Western Hemisphere, which includes continents like North and South America.
The location at 0 degrees latitude and 0 degrees longitude, where the equator and the Prime Meridian intersect, is nearest to the continent of Africa. Specifically, it is situated in the Gulf of Guinea, off the coast of West Africa, and is relatively close to countries like Ghana and Gabon. This point is often referred to as "Null Island," although it is not an island in the traditional sense.
You left off the last word in your question ... the verb. It was most likely going to besomething like "cross", and the answer to the question thus formed is "Africa".
The Prime Meridian passes through England. Turkey is at least 1000 miles east of it, maybe more like 2000-3000.
Like every other meridian, the Prime one only joins the poles,and forms a semi-circle.
