How Was the Top and Bottom of the Earth Determined If There Was No Direction in Space?

maps part of our lives and important tools that enable us to understand the Earth. How these maps were formed and of the North Pole Have you ever wondered why it is always shown above? After all, our Earth, a blue and round planet, is an endless void with neither bottom nor top. in the universe swimming. Then how can we assume that the Earth has a bottom and a top, that is, a north and a south?

The earth has a shape very close to round. But our maps show the world as flat. surface tries to squeeze it. In order to do this, many different mapping techniques developed and various methods were used to create world maps. On these maps, the countries of continents their size has changed. But one thing has remained constant: the North Pole is always up! If there is no concept of upside down in space, why are world maps still designed this way?

The main purpose of always having the same superior and inferior on world maps and globes is to set some reference points that will help people orient themselves.

Compass needles which is always the direction in which it is aligned, and Magnetic North The direction in which the so-called region is located is called north. Especially this region Reference point One of the reasons why it was chosen as the .

If the Earth has no fixed bottom or top, then what is Magnetic North and how come compasses always point in that direction?

Magnetic North is not the same thing as the North Pole, which is located at the top of the Earth. magnetic north, of the world part of into a magnetic field given name. world one magnet It is like a magnetic field, and there is always a magnetic field in one direction.

in a big world metals such as iron and nickel There is a hot and molten part formed and inside this molten part there is a rotating moving part. a liquid substance there is, in the name of this part “outer core“We say. magnetic fields creates. You can think of these magnetic fields as a bubble that surrounds the Earth. We call a part of this bubble magnetic north.

So why does such a magnetic field occur? Actually, the exact reason for this is unknown, but scientists have found that liquid substance relates to the interaction. This swirling liquid electrically charged particles The movement of particles can create a magnetic field.

Therefore, the directions shown on World maps are determined by Magnetic North.

Since the outer core, where Magnetic North is located, is a movable structure, Magnetic North is not always 100% in the same place and slightly displaced. For this reason, small deviations may occur in our compasses.

What we know today on maps Northern Hemisphere above, Southern Hemisphere One of the reasons why it is at the bottom is that these maps were found by people living in this sphere, and we interpret the Earth mostly from the framework drawn and conceptualized by these countries and in terms produced by them.

Easily in areas that catch our eye at first glance continents of Europe and North America we’ll see. However, these regions Southern HemisphereIt is not more central to the Earth than a country in . Nor are the Southern Hemisphere countries inferior or less important to the physical reality of Earth as a planet.

It is important to remember that maps are just a tool to show directions. The terms lower and upper have no real meaning here.

anywhere in the world when you stand You are not above or below the Earth.

For example, there is no difference between Turkey’s standing like this and the situation we are used to “for space”.

Therefore, for the purpose of showing direction, we use direction names, coordinates and many symbols and signs are tools that provide standardization for people to understand and use, rather than a geographical reality.
