The parallels themselves are oriented in the east-west direction. They're parallel to one another, as well as to Earth's equator.
What "latitude" denotes, however, is how far north or south of the equator you are. If you're located at 1° N, you're about 69 miles north of the equator. If you're at 89° N, you're about 69 miles from the North Pole. I said "about 69 miles" there because it's not exactly 69.000 miles, AND because it varies a tiny bit, due to Earth bulging out a tiny bit at the equator (because it's spinning at 1000 MPH). But don't let anyone tell you Earth is oval, because this bulge is something that we can measure. To look at it, no one would know it wasn't a perfect sphere.

How do lines of latitude run in relation to the equator?
Lines of latitude circle the earth, parallel to the equator.
Are the lengths of latitudes and longitudes equal give reasons?
The parallel of zero° latitude is a circle (called the 'equator')that's roughly 24,900 miles long.The parallel of 15° latitude is a circle that's roughly 24,000 miles long.The parallel of 30° latitude is a circle that's roughly 21,500 miles long.The parallel of 45° latitude is a circle that's roughly 17,600 miles long.The parallel of 60° latitude is a circle that's roughly 12,400 miles long.The parallel of 65° latitude is a circle that's roughly 10,500 miles long.The parallel of 70° latitude is a circle that's roughly 8,500 miles long.The parallel of 75° latitude is a circle that's roughly 6,400 miles long.The parallel of 80° latitude is a circle that's roughly 4,300 miles long.The parallel of 85° latitude is a circle that's roughly 2,170 miles long.The parallel of 87° latitude is a circle that's roughly 1,300 miles long.The parallel of 88° latitude is a circle that's roughly 870 miles long.The parallel of 89° latitude is a circle that's roughly 430 miles long.There is no 'parallel' of 90° latitude. It's a single point (the north or south pole),and has no length at all.
What is 49 parallel?
It is a circle of latitude that forms most of the US/Canada border.
What is the parallel latitude that circumscribes the polar tundra zone Tropic of Cancer Arctic Circle or Antarctic Circle?
The parallel latitude that circumscribes the polar tundra zone is the Arctic Circle in the Northern Hemisphere and the Antarctic Circle in the Southern Hemisphere. These latitudes mark the boundaries of the tundra biome, characterized by cold temperatures and a lack of trees due to permafrost.
How does eQuator form a great circle?
eQuator forms a great circle because it is a circle created by the intersection of a sphere and a plane that passes through the center of the sphere. The equator of the Earth, for example, is a great circle because it divides the Earth into two equal halves. The shortest path between any two points on a great circle is along the circle itself.
