First of all, let’s start by remembering one more fact; The earth is not flat, you can even see it with your own eyes. However, our earth is not round either, as we have learned since our early school years, the earth is an ellipse flattened from the poles and bulging out from the equator. This cute shape makes it revolve around both itself and the sun. follows a slightly sloping trajectory detected. This is what scientists call axial tilt.

Axis tilt is not something that only concerns astronomers, it directly affects our life on this planet because this tilt gives rise to seasons and this allows us to survive. In other words, Leyla, turning our summer into winter and our winter into summer, is actually a tilted axis. Bride what is axial tilt, what are the results, who found it? Let’s take a closer look at this kind of detail and see some of the effects this has on our planet.

What is axial tilt, who discovered it? Consequences of axial tilt:

What is axis tilt?

Earth’s rotation around the sun the angle between the axis of rotation and the orbital axis, called axial tilt. The axial tilt of our Earth is exactly 23.439281 degrees. However, this degree has changed over the years.

Measuring axial tilt will surprise many people because, as we know, space has no direction. When calculating axial tilt Fixed rotation trajectory with Earth quator line is aligned. The slope resulting from the alignment is accepted as the axle slope.

Who discovered axial tilt?

Hold on tight, we’re going back a long way. Since mankind has had the curiosity to explore space and the desire to understand the movements of the Earth, since the day it existed. The Earth’s axial slope was first discovered around 1100 BC. It has been measured in China and India. A Greek philosopher named Piteas made a very effective measurement around 350 BC.

The axial slope measured by Baghdad astronomers in 830 by the Caliph al-Mamun was used in the Arab world for many years. The first person to draw one of the real readings was the Muslim scholar Ibn al-Shatir, who lived in the 14th century. The most accurate and modern observation of axial tilt is: It was performed in 1584 by the Danish astronomer Tycho Brahe.

Consequences of axial tilt:

• Formation of the seasons
• Day and night times
• Sunbathe
• Seasonal changes and temperature changes
• climate zones

Of course none of us feel a slight dizziness because of gravity, but much more importantly, we live, the seasons. The biggest impact of axial tilt, which has many implications for astronomers, is the seasons, which are seen and felt by all. Especially since we are a country that lives all four seasons to the fullest, we know the axial tilt best.

Due to this inclined rotation of our world, the South and North Poles experience six months of day and night, respectively. Summer begins on the side of our Earth that faces the sun, The weather is getting warmer, the sunshine duration is increasing and we see the sun much higher. On the other hand, the opposite happens and the winter months begin.

Day and night duration, sunbathing, seasonal changes, temperature changes and all related All climatic zones are the result of axial tilt. In other words, as much as we talk about sunrise, sunset, hour, season and similar concepts, these are all the result of axial tilt.

The axle tilt changes:

While our Earth’s axial tilt is mostly constant, it changes in certain cycles. The biggest reason for this is: that our planet moves like a spinning top. In other words, the earth does not always rotate in a definite and fixed orbit, the tilt of the axis also changes when it is shaken with an irregular motion called nutation during rotation.

If we examine it in the geological time cycle, it has already existed for a period of 42 thousand years. The axial tilt has been determined to vary between 22 and 24.5 degrees. When we think about this process, we see many terrible droughts and ice ages. So even a few degrees of axial tilt can change a lot.

This axial tilt change process that takes thousands of years is actually smaller, It consists of cycles of approximately 18.6 years. It turns out that conditions such as daytime and nighttime duration, seasonal norms and sunshine duration change with each cycle. Even if there are no major changes, it is possible to say that in a few thousand years everything will be completely reversed.

What would happen if there was no axial tilt?

You may think that even if the axis wasn’t angled, these things wouldn’t happen, no, they wouldn’t. The sun’s rays would always come right, Yearly temperature differences would remain constant, seasons would not occur because the temperature was constant, there would be no poles, day and night would always be equal, and as a result of all this, life as we know it today might never occur.

It is much more important than we think that the slope of the axis creates the seasons that allow us to maintain our existing life. because Even small changes in regional We know it has the power to destroy the vitality of that region. And if we consider that it differs worldwide, the chances of not starting a life are quite high.

It gives the seasons, our night, our day and the climates. What is the axial tilt of the Earth, what are the consequences, what would it be without? We answered curious questions like, and talked about what you need to know about this seemingly simple yet essential ramp for all of us.
