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.

Why is the distance on a map showing 1 degree of longitude smaller than 1 degree of latitude yet both represent the same angle?
The lines of latitude represent degrees of arc being 111 kilometers per degree on the Earths surface. (111111.111 meters). That is how the meter was defined. Lines of longutude have this size on the equator but the lines converge at the poles where the distance between them becomes zero. So on maps, you will see that the distance of lines of latitude are always the same but those of longitude are smaller as distance increases away fro the equator.
How many feet are in one degree of latitude at 43 degrees longitude?
Every degree of latitude is the same size, regardless of its longitude. That size is about 69.11 miles, or 364,900 feet.
Do Lines of Longitude run parallel to each other?
Latitude lines run parallel to the Equator while longitudinal lines (also called meridians) run north-south. The latitude angle ranges from 0 degrees at the Equator to 90 degrees at either the north or south pole.
Are all the lines of latitude the same length?
no they are notThe lines of latitude run East/West. Each line forms a circle around the earth. The equator is at latitude zero degrees, and it encircles the earth. As we travel further and further North the earth, being a globe shape, gets narrower and narrower the further North we go. So all the circles get smaller and smaller as we move from the equator to the North. The lines of latitude are parallel to each other.Montreal, in Canada, is about 45o latitude, that is, halfway between the equator and the North pole, so a horizontal circle at that point would be smaller than the circle of latitude at the equator.At 80o North, the circle of latitude at that angle from the equator is just a small circle around the North pole. At 890 degrees North it is nearly at the North pole and the circle is very small. The North pole itself is at a latitude (angle) of 900, and there is no circle at all! It's smaller than a dot!The lines of longitude run from the North pole to the South pole. All the lines run from the top of the earth to the bottom of the earth. The lines converge at the poles, and are widest at the equator. Unlike the lines of latitude, all lines of longitude are the same length.For more information, see 'Related Links' below.
Do scientists use lines of latitude to describe the distance north or south of the equator?
Yes, and not only scientists. Cartographers and anyone who needs to know about locating things on the globe, or who needs to know location for navigation, communications systems, etc uses latitude and longitude.

How does a cartographer lessen distortions in size and shape by curving lines of longitude?
when you curve the lines of longitude it's more accurate because the globe is curved so it lessens the distortions.

Why does the distance between two consecutive latitude remain the same?
Visualize this: Cut the earth in half, and look into one half as if you are looking at a circular target. At the center is the center of the earth. Imagine a line from the center straight up to 12 o'clock and another line from center to 3 o'clock, forming a right angle. At three o'clock you have zero degrees as measured from the center; this is the equator. The individual degrees upward toward the pole at 90 degrees will define arcs on earth's surface of equal distances. These are degrees of latitude. Lines of longitude are farthest apart at the equator, and they all converge at the poles. So the angular size of any degree will be at its largest at the equator, and will be zero at the poles.
What is half-pitch in vlsi technology?
Pitch size is the sum of the (line width) and (space width) between 2 lines in a repeating pattern of lines to be printed on a wafer or something. half-pitch is the half of pitch size. Check double/multiple patterning for more.

Why does Greenland appear to be larger on a mercator projection than it does on a Robinson project?
The world is round, but maps are done on flat surfaces. To compensate for this, countries further from the equator get stretched. Greenland appears to be as big as all of Africa on a map like that, where in fact it is only about the size of the Democratic Republic of Congo. Alaska looks about half the size of the lower 48 states, but in reality it is much smaller. Watch for the lines of latitude and longitude to give a better idea of how big countries are in relation to each other.
Is the Greenland's size relative to the US greatly exaggerated on On Mercator projection?
Yes, it is! Since the Mercator tends to spread the meridians apart near the poles, any landmass to the North (or South) will look disproportionally large, compared to landmasses nearer the equator. Just look at a globe. You will see how the meridians (lines of longitude)converge at the North pole. Look at a Mercator projection. You will see those lines spread out so they are the same spacing as nearer the equator. That's how the Mercator makes Greenland look so HUGE, compared to the US... -Bob
What is the exact size of Mars?
Mars is considered to be the second smallest planet in the solar system. The angular diameter is between 3.5 to 25.1.

What did the French use to determine how long a meter would be?
The meter used the size of the Earth as a measurement. It is 1â„10,000,000 part of one half of a a meridian. A meridian is a measurement of longitude.
