Are lines of longitude also called meridians?
yesYes.
The length of a degree of longitude is the same at any latitude true or false?
False.
True or false is the points east of the prime meridian are located between 0 degree and 180 degrees east longitude?
Yes, all points east and west of the Prime Meridian are both between 0 and 180 degrees longitude because there are a total of 360 degrees of longitude on a globe divided into 180 degrees on each of the eastern and western hemispheres.
Is it false that the Panama Canal is located on a longitude of approximately 80 degrees W?
No, it is true. The Panama Canal is located at approximately 80 degrees west longitude.
Is it true that the lines of latitude called meridians never touch?
Not quite. Lines of latitude are called parallels, and they never touch each other. The meridians are lines of longitude, and all of them converge at the poles.
Are lines of longitude also called meridians?
yesYes.
The length of a degree of longitude is the same at any latitude true or false?
False.
Which is true about lines of longitude?
Every meridian of constant longitude is nominally a semi-circle, equal in length to all other meridians, and joining the Earth's north and south poles.
True or false is the points east of the prime meridian are located between 0 degree and 180 degrees east longitude?
Yes, all points east and west of the Prime Meridian are both between 0 and 180 degrees longitude because there are a total of 360 degrees of longitude on a globe divided into 180 degrees on each of the eastern and western hemispheres.
What is a map projection where the lines of longitude are parallel called?
That's true of the Mercator projection, among others.
Is it false that the Panama Canal is located on a longitude of approximately 80 degrees W?
No, it is true. The Panama Canal is located at approximately 80 degrees west longitude.
Where do the meridians meet?
The meridians meet at the poles, which are the points on Earth's surface where the lines of longitude converge. At the North Pole, all lines of longitude meet, and the same is true for the South Pole.
What direction must the ship be sailing along a meridian?
To sail along a meridian, one must sail true north or true south. Meridians of longitude run N/S.
Is it true that the main line of longitude is called the greenwich meridian?
You might say that. The thing that makes it the "main" one is the fact that by international agreement, it's the meridian that's accepted as zero longitude. So whenever the longitude of a place is stated, you always know that the number means an angle measured from the "Greenwich Meridian".
Why airplanes fly on longitude?
There's really no such thing as flying "on longitude". Do you mean that they stay on the same line of longitude when they're flying ? That would only be true as long as an airplane is flying exactly due north or due south. Any other time, it's flying through plenty of different longitudes.
Is it true that the lines of latitude called meridians never touch?
Not quite. Lines of latitude are called parallels, and they never touch each other. The meridians are lines of longitude, and all of them converge at the poles.
Are all points in Canada north or south latitude and eastor west longitude?
Every point in Canada has north latitude and west longitude. The same is true of the USA, except for part of Alaska's Aleutian chain, which crosses into the eastern hemisphere.
