Earth's equator. Correct world map
For most of us equator- this is nothing more than a symbolic line drawn on a map and denoting zero geographic latitude. However, there are lucky ones who managed to see this very line drawn along the ground. The real center of the world is in an Ecuadorian city Mitta del Mundo(translated from Spanish literally as “the middle of the world”), here it is literally a stone’s throw from the northern hemisphere to the southern.
The very name of the Republic of Ecuador translated from Spanish means “equator,” so the consonance is not accidental. The city of Quito, the capital of Ecuador, is indeed located on the equator, and the yellow line itself is in the “city” of Mitta del Mundo (it is located 15 km from Quito). Mitta del Mundo is actually more of a tourist center; no one lives here, but there are plenty of things to do for travelers.
The symbolic yellow line appeared in Mitta del Mundo after the French geodetic expedition of Charles Marie de La Condamine in 1736. This enthusiastic scientist explored Ecuador for 10 years, trying to find evidence that our planet is not perfectly flat, and at the same time to find the equator. And he succeeded, he found a point in the sky where the sun was at its zenith.
In 1936, on the occasion of the 200th anniversary of the expedition, the first monument in honor of the French Academy of Sciences appeared in Ecuador. And in 1979, Mitta del Mundo was turned into a tourist complex; the famous 30-meter tower topped with a globe was installed here, which does not cast a shadow on the days of the spring and autumn solstice. Along the alley leading to the monument, you can see busts of all members of the expedition.
In addition to the tower, there are other attractions in Mitta del Mundo: a church in which newlyweds can get married while in different hemispheres, and an ethnographic museum, the exhibitions of which are dedicated to the peoples inhabiting Ecuador. About one and a half million tourists come to Mitta del Mundo every year. Despite the fact that the latest GPS studies have proven that the equator is actually located 240 meters north of the indicated yellow line, the Ecuadorian authorities decided not to move the monument, and, apparently, satisfied tourists are not too upset by this discrepancy.

No. The equator passes through 13 countries of the world. Its length is approximately 40 thousand kilometers.
The equator passes through: Sao Tome and Principe, Gabon, Republic of the Congo, Democratic Republic of the Congo, Uganda, Kenya, Somalia, Maldives - maritime zone only, Indonesia,
Kiribati is an exclusive economic zone only,
USA - exclusive economic zone of Baker Island (US Minor Outlying Islands), Ecuador, Colombia, Brazil.
Equator is a conventional line that divides the globe into the Northern and Southern Hemispheres. Latitude at the equator is 0 and it is from here that the counting of geographic latitudes begins. The equator crosses three continents, such as Africa, Asia and South America. Moreover, it goes through three oceans: Atlantic, Indian and Pacific.
Along the equator there are lucky countries that have the warmest equatorial climate on the planet. Thirteen countries cross the equator: Ecuador and Colombia, Gabon and Congo, Brazil and Uganda, Kenya and Somalia, the Democratic Republic of Congo and Indonesia, the islands of Sao Tome and Principe, Kiribati and the Maldives. But Europe is the most distant part of the Eurasian continent from the equator.
The equator crosses not 20 countries of the world, but 13, so our answer to the question is No.
There is no correct answer, and according to Wikipedia, the equator passes through 14 countries. And these countries are located on the border of the hemispheres, and the equator accordingly divides these hemispheres into the southern and northern hemispheres.
To accurately answer how many countries the equator line crosses, and in my understanding this line should cross land, you can use a satellite map, which gives the most accurate geographic coordinates.
Let's start with Africa.
The island state of Sao Tome and Principe intersects the equator in the northern part of the island of Rolas
On the African continent the line passes through 6 countries (country names are underlined in red)
The Maldives is not suitable as the equator passes between the islands along the Laccadive Sea
The equator crosses Indonesia
Let's go even further to the right across the Pacific Ocean.
And here the equator does not pass through Kiribati, and the two islands - Jarvis and Baker, which informally belong to the United States, are located in different hemispheres.
In South America, the equator passes through three countries
In total, the equator crosses 11 countries by land.
The answer can be obtained by turning to the Internet or opening a Google map and walking along the entire length of the equator yourself. The second path is much more interesting; you can get acquainted with the geography of this latitude and learn about the existence of states that you have never heard of before. On your way you can come across islands, but their political affiliation is not indicated on the map. In any case, the answer will be negative - NO. The number of countries is significantly less than 20.
To answer this task, we need to take a look at the world map and count the number of countries whose territory is crossed by this imaginary line. It turns out that these countries are the only ones 13 , and that’s if you count the US-controlled Baker Islands, but not 20. So The answer here is NO.
It is believed that this conventional line divides our planet into the Southern Hemisphere and the Northern Hemisphere. This line crosses 13 countries, such as: Indonesia, Somalia, Brazil, Maldives, Ecuador, Gabon, Congo, Colombia and others. Therefore the correct answer is: no.
On Level 330 games in Odnoklassniki Yes or no, the correct answer is - NO.
The statement that the equator passes through 20 countries of the world is not true.
The equator passes through 13 countries of the world.
Need to remember.
The number of countries through which the equator passes is not at all difficult to calculate, and this has been done for a long time. There were thirteen of them. Here you can just take a quick glance at the world map and it will be clear that there will be less than 20 such countries. The answer is NO.
Twenty is a lot; the equator doesn’t have that much length. Now, if the countries were very small, then yes, but otherwise - NO, it does not pass through so many states.
There are only thirteen countries on his way.
No. Here is the list:
The equator is an imaginary circular line that encircles the entire globe and passes through the center of the Earth.
The equator line is perpendicular to the axis of rotation of our planet and is located at an equal distance from both poles.
Equator: what is it and why is it needed?
So, the equator is an imaginary line. Why did serious scientists need to imagine some lines outlining the Earth? Then, the equator, like meridians, parallels and other dividers of the planet, which exist only in the imagination and on paper, make it possible to make calculations, navigate in the sea, on land and in the air, determine the location of various objects, etc.
The equator divides the Earth into the Northern and Southern Hemispheres and serves as the origin of geographic latitude: the latitude of the equator is 0 degrees. It helps to navigate the planet's climate zones. The equatorial part of the Earth receives the largest amount of sunlight. Accordingly, the further the territories are located from the equatorial line and the closer they are to the poles, the less sun they receive.
The equatorial region is an eternal summer, where the air is always hot and very humid due to constant evaporation. At the equator, day is always equal to night. The sun is at its zenith - it shines vertically downwards - only at the equator and only twice a year (on those days on which the equinoxes occur in most geographic zones of the Earth).
The equator passes through 14 countries. Cities located directly on the line: Macapa (Brazil), Quito (Ecuador), Nakuru and Kisumu (Kenya), Pontinac (Kalimanta island, Indonesia), Mbandaka (Republic of the Congo), Kampala (capital of Uganda).
Equator length
The equator is the longest parallel to the Earth. Its length is 40.075 km. The first who was able to approximately calculate the extent of the equator was Eratosthenes, an ancient Greek astronomer and mathematician. To do this, he measured the time during which the sun's rays reached the bottom of a deep well. This helped him calculate the length of the radius of the Earth and, accordingly, the equator thanks to the formula for circumference.
It should be noted that the Earth is not a perfect circle, so its radius differs slightly in different parts. For example, the radius at the equator is 6378.25 km, and the radius at the poles is 6356.86 km. Therefore, to solve problems of calculating the length of the equator, the radius is taken equal to 6371 km.
The length of the equator is one of the key metric characteristics of our planet. It is used for calculations not only in geography and geodesy, but in astronomy and astrology.
He established that the Earth has the shape of a ball, and he became interested in the very size of the celestial body. It should be noted that the Earth is not a sphere. It has the shape of an ellipse, i.e. a ball flattened at the poles. The equator is a line that can theoretically be drawn around. It currently crosses territory 14.
For ancient scientists, finding the length of the equator was not an easy task. For the first time, the Greek mathematician and astronomer Eratosthenes was able to determine the circumference of a celestial body. It was he who found the length of the earth's radius and calculated the length of an imaginary line. The scientist was able to achieve this result by measuring the time it took for the sun's rays to reach the bottom of the well. Of course, as a result of such studies, Eratosthenes calculated the approximate length of the radius of the Earth, and therefore the equator.
To calculate the Earth's equator, you need to know the radius of the planet. As already noted, the Earth is flattened at the poles, so its radius is not the same. It was found that the equatorial radius is 6378 km 245 meters, and the polar radius is 6356 km 863 meters. The amount of compression of the Earth at the poles is insignificant, therefore, when solving some problems, the radius is taken equal to 6371 km.
So, in order to find the length of the equator, you need to use the formula for the circumference of a circle: L=2?R, where R is the radius of the circle. Equator length = 2x3.1416x6378.245 = 40,076 km. For approximate calculations, the length of the equator is taken to be 40,000 km. All other planes that are parallel to the equatorial plane are called parallels. They are significantly shorter than the equator and serve to determine geographic latitude. At the equator, latitude is zero. The length of the equator is one of the main characteristics of any planet. It is constantly used in calculations by astronomers and astrologers.

This question plagued members of the French Academy of Sciences at the end of the 18th century. After all, on March 19, 1791, a new metric system of measures was introduced. A meter was theoretically equal to one ten-millionth of a quarter of the length of the earth's meridian. But the length of the meridian itself has not yet been measured in practice. They decided to measure using the triangulation method.
Triangulation method
Using the triangulation method, we planned between Dunkirk and Barcelona. This distance is nine and a half degrees of the arc of the meridian. A degree is one hundred and eightieth of the length of the meridian. The work was entrusted to Cesar François Cassini, Andrien Marie Legendre and Pierre Méchain.
Triangulation involved marking the route along a network of highly visible landmarks: towers, peaks, church spiers, etc. The dots represented a series of connected triangles. Knowing all the angles formed by two adjacent triangles and the lengths in at least one of the triangles, you can use trigonometry to determine the lengths of all sides in both triangles.
The method had already been successfully used in 1718 by Jean Cassini, father of Caesar François, between Dunkirk and Collioure.
During their work, surveyors had to endure a lot and overcome many difficulties. Due to the difficult political situation in the country during the Great French Revolution, they were repeatedly arrested, damaged and geodetic equipment destroyed. As a result, measurements were completed only in 1799, three years later than planned.
Space triangulation
With millimeter accuracy, the length of the meridian was established in the second half using space triangulation. The essence of this method is simple.
Several objects on the earth's surface are simultaneously observed from a satellite. Their coordinates are reduced to a single system. Triangulation points located on different continents are connected.
In this way, the distances between the continents were determined with a high degree of accuracy. Previously they were known only approximately. After all, it is not possible to apply classical triangulation methods on the water surface.
In addition, using the method of cosmic triangulation, the shape of our planet was clarified. It turned out that it was somewhat deviated from spherical and slightly pear-shaped. The “pear” is slightly elongated to the north and slightly flattened to the south.
And the surface of the world's oceans, to one degree or another, copies the outlines of the ocean floor. Protrusions and depressions have been found on the surfaces of seas and oceans.
