InfoKekinian.com – Latitudes are a network of lines drawn around the earth horizontally, parallel to the equator. The latitude function plays an important role in navigation and mapping.
Lines of latitude are also known as parallels because these lines are always parallel to one another.
Each line of latitude has a different degree value, ranging from 0° at the equator to 90° at the north or south pole.
Since ancient times, humans have used latitude to determine the position of a place on Earth, whether on land or at sea.
Latitude is also the basis for determining time zones around the world, where every 15 degrees difference between two adjacent latitudes represents one hour of time difference.
In this article, we will discuss more about the meaning and measurement of latitude, the function of latitude, its important role in determining global climate patterns, and the various types of latitudes that exist on Earth.
In addition, we will also discuss how latitude affects time zones and their important role in global navigation.
Definition of Latitude
Latitudes are horizontal lines drawn over the surface of the Earth. These lines are drawn parallel to the equator and serve to divide the Earth into regions.
Each latitude has a different degree value and this value increases the further you are from the equator.
Latitude measurements are made using degrees which are divided into 360 parts, where each part represents 1 degree.
The equator is a line of latitude that has a value of 0° and is located midway between the North Pole and the South Pole.
Meanwhile, at the North and South Poles there are latitudes called 90° North Latitude and 90° South Latitude.
Here are some latitude functions:
1. Determining Position on Earth
The function of the first latitude is used to determine the position on earth, both horizontally and vertically.
In geographic coordinates, latitude indicates the position north or south of the equator.
By knowing the latitude of a place, we can determine the relative position of that place to the equator.
2. Determining Climate and Weather
Function latitude the second is that it affects the climate and weather somewhere. The closer a place is to the equator, the hotter the climate.
Conversely, the farther from the equator, the colder the climate. In addition, latitude also affects the amount of rainfall in a place.
3. Determining Time
The next latitude function is also used to determine the time somewhere. In coordinate time, latitude indicates the different time zones for each place on earth.
By knowing the latitude of a place, we can determine the time difference with other places on earth.
The Important Role of Latitudes
One important role of latitude is in determining global climate patterns. Latitudes help in dividing the Earth into regions that have different climatic characteristics.
This is due to differences in the amount of sunlight received by each region, which is influenced by the degree of latitude where the region is located.
Latitude also plays an important role in navigation and mapping. In navigation, latitude is used to determine the position of ships or aircraft at sea or in the air. Meanwhile, in mapping, latitude is used to determine the coordinates of a place on Earth.
There are several types of latitude that are important to know, namely:
- Equator (0°)
- Tropic of Cancer (23.5° N)
- Tropic of Capricorn (23.5° S)
- Arctic Circle (66.5° N)
- Antarctic Circle (66.5° S)
Each type of latitude has different characteristics and roles. The equator is the latitude that divides the Earth into the Northern and Southern hemispheres.
The Tropics of Cancer and Capricorn are the latitudes that mark the sun's farthest point from the equator during summer.
Meanwhile, the Arctic and Antarctic Circles are latitudes that mark the farthest point from the sun during winter.
The Effect of Latitude on Time Zones
As previously mentioned, latitude is also the basis for determining time zones around the world.
Every 15 degrees difference between two adjacent latitudes represents one hour of time difference. Therefore, there are 24 time zones around the world.
The time zone is set based on the latitude passing through Greenwich, England with a value of degrees 0°. This latitude is known as the Greenwich Meridian.
Areas west of the Greenwich Meridian have an earlier time zone than areas east of the Greenwich Meridian.
For example, Indonesia has three time zones, namely West Indonesia Time (WIB) which is west of the Greenwich Meridian with a value of 7.5 degrees, Central Indonesia Time (WITA) which is between WIB and East Indonesia Time (WIT), and Eastern Indonesia Time (WIT) which is east of the Greenwich Meridian with a value of 9 degrees.
The Important Role of Latitudes in Global Navigation
Latitude also plays an important role in global navigation. Latitude is used as a reference in determining the position of an object or place on Earth.
In marine navigation, latitude is used as a reference in determining the latitude of the ship, namely the position of the ship to the north or south of the equator.
Meanwhile, in air navigation, latitude is used as a reference in determining the latitude or position of an aircraft north or south of the equator.
Latitude is also used in the GPS (Global Positioning System) system which is used to determine the position of an object or place on Earth.
GPS works by sending signals from satellites orbiting around the Earth.
This signal is received by the GPS receiver which then calculates the position of the object or place based on the information from the signal, including information about latitude.
The Future of Latitudes
In the future, role latitude will be increasingly important in global navigation, especially in the face of increasingly sophisticated technological developments.
Latitude will continue to be a reference in determining the position of an object or place on Earth, both on land and at sea and in the air.
However, there is also the potential for negative impacts on global navigation caused by global climate change.
Global climate change can affect climate characteristics in certain regions which will have an impact on global navigation.
Therefore, the role of latitudes in dividing the Earth into regions with different climatic characteristics will become increasingly important in facing future challenges.
Climate Division Based on Latitude
Climate is the average weather conditions in an area over a long period of time. Latitude affects climate because latitude affects the amount of sunlight an area receives.
In general, the closer an area is to the equator, the higher the temperature, while the farther from the equator, the lower the temperature.
Based on latitude, the Earth's region is divided into three climate zones, namely the tropical zone, the temperate zone, and the cold zone.
The tropical zone lies between the Equator and the Tropic of Cancer to the north and the Tropic of Capricorn to the south.
The tropical region has a hot and humid climate all year round and affects most of Southeast Asia, Africa, Central America, and South America.
The temperate zone is located between the Tropic of Cancer and the Arctic Circle to the north and the Tropic of Capricorn and the Antarctic Circle to the south.
This region has a more moderate climate and clear winters. Some countries that are in the moderate zone are the United States, Canada, Japan, Korea, and several countries in Europe.
The cold zone is located in the Arctic Circle to the north and the Antarctic Circle to the south. This region has very low temperatures and very long winters.
Some countries that are in the cold zone are Russia, Norway, Iceland, Greenland, and Antarctica.
Territorial division based on climate zones is very important in human life because climate greatly influences the pattern of life and human activities in the region.
By understanding the division of land based on latitude and climate zones, we can make better decisions in dealing with climate-related challenges such as natural disasters and global climate change.
Example of Using Latitude
Here are some examples of using latitude to determine a location on earth:
1. Determining Geographical Position
Latitude is used to determine the geographical position of a place on earth.
For example, Jakarta is located at latitude 6 degrees 12′ LU, which means that Jakarta is located in the northern hemisphere and 6 degrees 12 minutes from the equator.
2. Determining Climate and Weather
Latitude also affects the climate and weather in a place. For example, the tropics are located between latitudes 23.5 degrees North Latitude and 23.5 degrees South Latitude.
The tropics have a hot and humid climate all year round because they are close to the equator.
3. Determine the Time Zone
Latitude is also used to determine the time zone of a place on earth.
For example, Indonesia has three different time zones, namely WIB (Western Indonesian Time), WITA (Central Indonesian Time), and WIT (Eastern Indonesian Time).
Latitude 120 degrees East (East Longitude) is used as a reference to separate the time zones.
