any meridian of longitude
Each meridian of constant longitude is a semicircle that joins the Earth's north and south poles. They stay put.
They are both imaginary lines on the Earth's surface. To say that they are both circles... an answer you might have been expecting ... would be a wholly inappropriate statement, because a meridian of longitude is only a semicircle.
Yes. Almost exactly. The equator is a full circle around the Earth, but a meridian of longitude connects the north and south poles, so it's a semicircle. The only reason a meridian isn't exactly half the length of the equator is that the Earth's polar diameter is not exactly the same as its equatorial diameter. The Earth is slightly 'shorter' than it is 'wide', which is also occasionally true of some people you see walking around.
you find a location with latitude and longitude. longitude is east and West.
