Unlike the parallels of latitude, which are defined by the rotational axis of the Earth (the poles being 90° and the Equator 0°), the Prime Meridian is arbitrary. By international convention, the modern Prime Meridian is one passing through Greenwich, London, United Kingdom, known as the International Meridian or Greenwich Meridian. Historically, various meridians have been used, including four different ones through Greenwich. Heading south from the North Pole, the Prime Meridian first passes through the United Kingdom (the most northerly land on the meridian is the shore (53°45′34″N) southeast of the Sand-le-Mere caravan park east of Kingston upon Hull, England). It then passes through France, Spain, Algeria, Mali, Burkina Faso, Togo, and Ghana, and then through Queen Maud Land to the South Pole. The Prime Meridian and the opposite 180th meridian (at 180° longitude), which the International Date Line generally follows, form a great circle that divides the Earth into the Eastern and Western Hemispheres.

What is used to locate places on earth's surface?
A Map, in one one of these different types of projections: Mercator, Gnomonic, and Polyconic. Mercator - Shows the whole world except for the poles. Gnomonic - A circle projection showing, most often, the poles but sometimes other small places of the earth. Polyconic - Made as if a cone of paper had been wrapped around the earth, often used for places in the middle latitudes, such as the United States.
What are the two kinds of location?
Absolute location refers to the precise coordinates of a place on Earth's surface, usually using latitude and longitude. Relative location, on the other hand, describes the position of a place in relation to other landmarks or geographic features.
What 4 types of earth spheres?
The Earth is split into four imaginary hemispheres. The Northern Hemisphere, and the Southern Hemisphere are split by the Equator (zero latitude). The Western Hemisphere and the Eastern Hemisphere are split by the Prime Meridian (zero longitude).
What is the meaning of geocentric?
Having reference to the earth as center; in relation to or seen from the earth, -- usually opposed to heliocentric, as seen from the sun; as, the geocentric longitude or latitude of a planet., Having reference to the center of the earth.
What is the affect of latitude n longitude of earth on gravity?
Your weight at the north or south pole would be ever so slightly greater than it is at the equator, because the Earth is slightly fatter around the equator than it is around the poles, so if you're standing on the equator, you're slightly farther from the Earth's center of mass than you are if you're standing on one of the poles. Other than that, your location on the surface of the Earth has no effect at all on the forces of gravity that attract you and the Earth toward each other.
What is greenwich 0 degree called?
0 degrees longitude, which runs through Greenwich is called the "prime meridian."
A sentence with the word prime meridian?
The prime meridian is the zero degree vertical longitude line on the globe of the Earth. An example sentence would be: She used to live close to the prime meridian.
What time is it at greenwich at longitude 74 degree west?
If you tell us the time at either Greenwich or at 74° west, then we can tell you the time at the other point. They do track together, but both of them keep changing.
Is greenwich meridian a line of longitude?
Yes. Every "meridian" is an imaginary line on the Earth that joins the north and south poles and has the same longitude at every point on it. The Greenwich meridian is the one that passes through the Royal Observatory in England. It's defined as zero longitude, and all other longitudes on Earth are numbered starting at that one.
What line of longitude is the basis of all other longitude measurements?
Zero degrees longitude, sometimes called the Greenwich Meridian after the observatory in Greenwich England where the system of latitude and longitude was worked out. The happy accident is that the 180 degree meridian, the International Date Line, is situated in the ocean where it causes relatively little trouble for major land masses.
What are the 2 major line of longitude?
The major longitude is the Greenwich meridian. The other is the line of longitude on the opposite side of the earth - more or less the International Date Line. Except that it is not a straight pole-to-pole line.
What is found 0 degree longitude?
The Prime Meridian is found at 0 degrees longitude. Additionally, this is the longitude line that goes through Greenwich, England which marks the base time zone GMT or UTC that other time zones are relative to.
Is the greenwich median a line of longitude?
Yes, the Greenwich Meridian is a line of longitude that runs from the North Pole to the South Pole, passing through the Royal Observatory in Greenwich, England. It is defined as 0 degrees longitude and serves as the prime meridian from which all other longitudes are measured.
What is the name of the imaginary vertical line that circles the earth and is found at zero degrees longitude?
the Prime Meridian or Greenwich Meridian and runs through Greenwich England ________________________________ You're probably thinking of the Prime Meridian, but the Prime Meridian doesn't circle the Earth; it only covers half of the Earth. The other half of the circle is the "anti-meridian" at longitude 180 degrees. (East or west? Both, and neither.)
Is the Greenwich meridian at lonitude of 0?
Yes, it does. In fact, the Prime Meridian - the zero mark for longitude - is defined as the logitude of the Royal Observatory in Greenwich, England.
Londons borough of green which lies at 0 degrees longitude is known by what other name?
The London borough of Greenwich, located at 0 degrees longitude, is also known as the "Royal Borough of Greenwich." It is famous for landmarks such as the Greenwich Meridian Line and the Royal Observatory.
What is the prime meredian?
The Prime Meridian is an imaginary line betyween the north and south poles that crosses the Royal observatory at Greenwich, just outside of London. By international agreement, that meridian is defined as zero longitude, from which all longitudes on Earth are measured.
