Despite the fact that there are almost no inaccessible places left on our planet, it still hides many more secrets than we can imagine. Some of them are being studied by scientists, but many have such an incomprehensible essence that it becomes problematic to give a full answer to the question of what they are.
THE MAIN MYSTERY OF OUR PLANET IS THE WORLD OCEAN.
This “earthly cosmos” for modern man represents a sphere that is only slightly less mysterious than for people in ancient times.
Despite all the achievements of technological progress, the waters of the Earth are currently studied by no more than 5%, which means that people are still very far from having the right to consider themselves masters of the planet. In such a situation, it is impossible to exclude, among other things, the existence of many sea monsters that still remain characters of myths and legends.
As strange as it may sound, there are places on planet Earth where the forces of gravity differ from the general norm. For example, on the territory of Hudson Bay, they are slightly smaller than in other parts of the planet, and this allows you to perform various works here with less energy costs. Such an anomaly occurs due to the fact that there are no land areas in the bay, and a large amount of magma has accumulated on its bottom under tectonic plates. Studies of Hudson Bay are constantly taking place, but scientists still cannot answer the question why such a phenomenon is not observed throughout the ocean.
Everyone knows that the duration of the day on Earth is about 24 hours. However, this was not always the case: according to science, millions of years ago, the Earth’s day lasted only 22 hours. It turns out that every year our planet slows down its rotation a little, and after some time, even for a very long time, the dream of all workaholics will come true: 25 hours will fit in a day. Scientists explain this phenomenon by the influence of several factors. Most often you can hear about the influence on the planet of its satellite – the Moon, the attraction of which is able to slow down the speed of rotation of the Earth a little. But this is not the only theory. Some believe that the slowdown is due to the activity of the Earth’s core: constantly producing a large amount of heat, it gradually depletes its energy reserves, which contributes to a decrease in speed.
The theory of the “purple Earth” claims that in ancient times all the plants on the planet had a purple hue instead of the usual green. There is not enough evidence for this theory, but many experiments admit the possibility that purple plants existed on Earth before green plants, which was facilitated by the uniqueness of the atmosphere and a fairly large ozone layer, the thickness of which has significantly decreased these days.
