Latitude is a circle drawn on a map that runs perpendicular to the Equator, often known as a parallel. Concerning maps, latitudes are measured from north to south. Their names derive from the angle that forms a line that connects the Earth’s latitude to the Equator, and the other way around. To know where you are concerning the Equator, you need to know your latitude and longitude. The northern latitudes are used to pinpoint the location in the Northern Hemisphere. On the other hand, sites in the Southern Hemisphere are located at southern latitudes, which stands for the south.
Definition of Latitude
The north-south location of a place on the globe is shown by the latitude, which runs east-west across a map. 0 degrees is the Equator, and 90 degrees is the poles, where the lines of latitude intersect. As a result, the closer a location is to the South or the North Pole, the greater its latitude value. The Northern Hemisphere encompasses the area north of the Equator, whereas the Southern Hemisphere encompasses the region south of the Equator.
Definition of Longitude
Longitude lines, often known as meridians, are invisible lines that split the globe. Even though they run north-south from pole to pole, they only measure distances in any direction. There are three ways to measure longitude: degrees, minutes, and seconds. The Equator, where longitude lines are the widest apart, is where they meet, even though latitude lines have consistently been evenly spaced.
To begin, what exactly is the Equator?
A large circle that circles the Earth and is perpendicular to its axis, passing through all points on its surface equally distance from the polar geographic regions on either side. The hypothetical line on the planet’s surface from which latitude is calculated is the terrestrial Equator, which separates the planet’s northern and southern hemispheres. Although, the difference between latitude and longitude lies in its equator measurements.
Parallels of latitude
Imaginary circles that run perpendicular to the Equator are referred to as parallels of latitudes. Even though these circles have different centers, all of them are located on the axis of the Earth, which connects them.
Meridians of longitude
Meridians of longitudes are all of the hypothetical circles perpendicular to the Equator, and they are all of the fictitious circles perpendicular to the Equator. There is a joint center to all of these circles, which is the center of this planet.
Different time zones exist across the world
There are 24 distinct time zones on the planet due to its yearly rotation around its axis. The prime meridian at Greenwich, often known as Greenwich Mean Time, serves as the beginning point for all of these time zones. According to theory, an extra hour can be gained or lost for every 15 degrees east or west of Greenwich. On the other hand, time zones do not cross the center of nations in reality. Many time zones exist in large nations with thousands of kilometers between them, such as the United States or Russia.
The Earth’s Heat Zones
For at least one day each year, the midday sun lies directly above all latitudes between the Tropics of Cancer and Capricorn. As a result, this region is known as the Torrid Zone since it gets the most heat.
On any latitude other than the Tropics of Cancer and Capricorn, the midday sun never shines directly above throughout the daytime. Sun’s rays continued to decrease in angle as they got closer to the poles. In the Northern Hemisphere, the locations between the Tropic of Cancer and the Arctic Circle have mild temperatures, while those between the Tropic of Capricorn and the Antarctic Circle have cold ones. As a result, these regions are referred to as Temperate Zones.
Northern and Southern Hemisphere regions that lie between these two lines of latitude are very frigid. The Sun doesn’t rise very high in the sky here. Since its rays are constantly angled downward, they produce less heat. These are known as Frigid Zones because of their frigid temperatures.
International Date Line
Located between the South and North Poles, the International Date Line is a demarcation line that divides the calendar year into two distinct periods. It makes its way across the Pacific, often following a 180-degree longitude line but diverting around a few territories and island groupings. If you go from east to west on the dateline, you lose one day or 24 hours. If you go from west to east, you gain one day or 24 hours.
Conclusion
Moreover, using the Equator as a reference point, we may calculate distance using the longitude and latitude lines. Latitudes assist us in determining the distance between any two points concerning the Equator, which is based on the degree of latitude at each location. The coordinates of longitude and latitude assist us in determining the location of any point on the planet. In the absence of longitude and latitude, we would be unable to locate the positions of continents and other areas on the planet.
