Yes, Prime Meridian is an imaginary circle..
The 180th meridian or antimeridian is the meridian which is 180° east or west of the Prime Meridian with which it forms a great circle.
The 180th meridian or antimeridian is the meridian which is 180° east or west of the Prime Meridian with which it forms a great circle.
The Prime Meridian and the meridian of 180° longitude combine to form a great circle on the Earth. Each of them alone is a semi-circle.
The Prime Meridian is complete exactly as it appears on maps and globes. It forms a half-circle, and it isn't missing anything. When joined with the Prime Meridian, the 180-degree meridian of longitude forms a complete great circle.
Like every other meridian, the Prime one only joins the poles,and forms a semi-circle.
180th Meridian
The International Date Line combined with the Prime Meridian makes a complete circle around the Earth. The Prime Meridian is at 0 degrees longitude, and the International Date Line is opposite it at 180 degrees longitude.
This imaginary circle is called the prime meridian. it is an imaginary line that circles the globe vertically and is typically measured as beginning in Greenwich, England.
The Norwegian sea.
The Prime Meridian and the meridian of 180° longitude combine to forma great circle on the Earth. Each of them alone is a semi-circle.Every parallel of latitude also circles the Earth completely, but among those,only the equator is a great circle.
Both. It runs from Pole to Pole. Every meridian of longitude on Earth crosses the Antarctic Circle,the Arctic Circle, and every other parallel of latitude on Earth.Yes to both.The prime meridian is a line of longitude and therefore passes through both the Arctic and Antarctic circles, which are lines of lattitude.
Every meridian of longitude is a semi-circle that joins the north and south poles.
