The five major parallels of latitudes from north to south are called: Arctic Circle, Tropic of Cancer, Equator, Tropic of Capricorn, and the Antarctic Circle. On a maps where the orientation of the map is either due north or due south, latitude appears as horizontal lines.
Similarly, can you have parallel curves?
As for parallel lines, a normal line to a curve is also normal to its parallels. When parallel curves are constructed they will have cusps when the distance from the curve matches the radius of curvature. These are the points where the curve touches the evolute.
How many tangents can a circle have?
Exactly 0 tangents can be drawn through a circle. A tangent intersects a circle in only one point so it does not actually enter the area of the circle. An infinite number of tangents to a given circle can be drawn since their is no limit to the points a tangent could intersect.
How many parallels are there in the world?
Everything north of the equator is known as the Northern Hemisphere and everything south of the equator is known as the Southern Hemisphere. Lines of latitude are called parallels and in total there are 180 degrees of latitude. The distance between each degree of latitude is about 69 miles (110 kilometers).
Which is the longest parallel?
The equator is the circle that is equidistant from the North Pole and South Pole. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere. Of the parallels or circles of latitude, it is the longest, and the only ‘great circle’ (a circle on the surface of the Earth, centered on Earth’s center).
Are all spheres circles?
Such a circle can be formed as the intersection of a sphere and a plane, or of two spheres. A circle on a sphere whose plane passes through the center of the sphere is called a great circle; otherwise it is a small circle.
Which is the largest latitude?
Longitude is in the range -180 and +180 specifying coordinates west and east of the Prime Meridian, respectively. For reference, the Equator has a latitude of 0°, the North pole has a latitude of 90° north (written 90° N or +90°), and the South pole has a latitude of -90°.
What are the five major lines of latitude?
The five major circles of latitude are, from north to south:
The Arctic Circle (66°N)
The Tropic of Cancer (23° N)
The Equator (0° latitude)
The Tropic of Capricorn (23°S)
The Antarctic Circle (66°S)
Which is the longest latitude and why?
On a globe of the Earth, lines of latitude are circles of different size. The longest is the equator, whose latitude is zero, while at the poles–at latitudes 90° north and 90° south (or -90°) the circles shrink to a point.
What are the most important lines of latitude and longitude?
The most important line of latitude is the equator, which runs horizontally around the fattest part of the earth. The most important longitude line is the Prime Meridian which runs vertically and goes through Greenwich, England.
What are some examples of latitude?
An example would be the equator, which is at zero degrees of latitude. Other important parallels include the Tropic of Cancer (at 23.4 degrees North), the Tropic of Capricorn (at 23.4 degrees South), the Arctic Circle (at 66.5 at degrees North), and the Antarctic Circle (at 66.5 degrees South).
What degree of latitude is the Arctic Circle?
The Arctic Circle is the parallel of latitude that runs 66° 33´ 39″ (or 66.56083°) north of the Equator and is one of the five major circles of latitude that mark maps of the Earth. Everything north of this circle is known as the Arctic, and the zone just to the south of this circle is the Northern Temperate Zone.
How many degrees of latitude are there in total?
The primary unit in which longitude and latitude are given is degrees (°). There are 360° of longitude (180° E ↔ 180° W) and 180° of latitude (90° N ↔ 90° S). Each degree can be broken into 60 minutes (‘). Each minute can be divided into 60 seconds (”).
What parallel is located at 23.5 degrees south?
Tropics of Cancer and Capricorn: Located at 23.5 degrees North and 23.5 degrees South of the Equator, this area of Planet Earth (between those two lines) is known as the “Tropics,” and is indicated with a lighter blue color on the above globe.
What is the line of latitude at 23.5 degrees north?
The Tropic of Cancer is the circle marking the latitude 23.5 degrees north, where the sun is directly overhead at noon on June 21, the beginning of summer in the northern hemisphere.
What is the difference between longitude and latitude?
Any point on the Equator’s circle is of latitude 0°, the top north is 90° North, the top south is 90° South. Circles parallels to the Equator are of the same latitude. Longitude: it is the West/East value of a point on Earth. Longitudes are lines going from south pole to north pole.
What is the area between the Tropic of Cancer and the Arctic Circle?
The area between these circles and the poles constitute the Frigid Zones, or we might say the region of perpetual winter. Between the Arctic Circle and the Tropic of Cancer is the North Temperate Zone, and its southern companion, the South Temperate Zone lies between the Tropic of Capricorn and the Antarctic Circle.
What is the other name given to the 0 degree meridian?
The meridian through Greenwich (inside Greenwich Park), England, called the Prime Meridian, was set at zero degrees of longitude, while other meridians were defined by the angle at the center of the earth between where it and the prime meridian cross the equator.
What is the degree for the prime meridian?
area of the Earth east of the prime meridian and west of the International Date Line. imaginary line around the Earth, another planet, or star running east-west, 0 degrees latitude. line of longitude at roughly 180 degrees.
Which is latitude?
Latitude. Lines of latitude measure north-south position between the poles. The equator is defined as 0 degrees, the North Pole is 90 degrees north, and the South Pole is 90 degrees south. Lines of latitude are all parallel to each other, thus they are often referred to as parallels.
How many degrees difference is there between each parallel and meridian on the globe?
Do the lines of longitude measure the distance north and south, or east and west, on a globe? east and west. How many degrees difference is there between each parallel and meridian shown on the globes? 15 degrees.
What is the name of the main line of latitude?
Important lines of latitude:
the equator (0°)
the Tropic of Cancer (23.5° north)
the Tropic of Capricorn (23.5° south)
the Arctic circle (66.5° north)
the Antarctic circle (66.5° south)
the North Pole (90° north)
the South Pole (90° south)
Which is the Prime Meridian?
A prime meridian is a meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its antimeridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides the sphere, e.g., Earth, into two hemispheres.
What is another name for a line of latitude?
Parallels are another name for lines of latitude. You will see that these lines do not converge, or come together, anywhere on the globe. We call these parallels because they are always an equal distance apart. The first parallel is the equator.
