"HOUSE SPARROW"

The sparrow is a small bird. Like other birds, these birds have a great contribution not only in human life but also in the balance of nature. This bird contributes to many things in nature in its own way.

In fact, in summer, they are more visible around human settlements. And during the rainy season, their habitat is mostly in the forest. But if you want to observe sparrows, then summer and winter are very good seasons. If you look at the number of sparrows, it seems to be decreasing from the cities. And the sparrows are still very good in the small villages around the cities, the lands adjoining the villages, or the farms. And even today this part is very rich for observation.

In cities nowadays where concrete forests are growing in large numbers, large numbers of houses are growing, sparrows have almost disappeared from there. The sparrow does not need very large trees for habitat. The sparrow's habitat is the shrubs, acacias and scrub forests. And this is where they live. What happens is that all these are broken in the summer, so somewhere we are unknowingly inflicting wounds on their habitat. So we feel that their number is decreasing.

The way in which the number of tigers has come down drastically has made us realize the importance of tigers today. Therefore, efforts are being made everywhere to save the tigers. And their reserve forests have also been created all over the world and they are being conserved very well. But in the case of sparrows, we do not have such awareness. It is equally true that sparrow is contributing as much as we can to maintaining the balance of this environment.

If the environment is saved, the sparrow can definitely survive. 

"TOP 10 AMAZING FACTS ABOUT THE EARTH"

You would not know 10 things related to the earth. Earth, our earth, our home, our only address in this entire universe. We humans are trying to unravel the secrets of this earth. But no one knows how many secrets this blue house is hiding in its womb.

Hello friends and welcome to my blog Value of Nature. And today we are going to tell you 10 such things related to the earth, which you have never heard of before. So let's know about them.

1. A day wasn't always of 24 hours-  
   

         The day was not always 24 hours. Now I will ask you how many hours are there in a day, then you will say that there are 24 hours. This is a simple question, but friends were not always so. About 70 million years ago, there used to be only 21 hours and 56 minutes in a day. In fact, due to the gravity of the moon, sun and other planets, there is a lot of change in the orbit of the earth due to the tides coming in the sea. And every 100 years, the time of one day works out to 1.4 milliseconds. Due to the natural objections that occur on Earth, the time of day also changes. The 2011 earthquake in Japan reduced the time of 1 day by about 1.4 milliseconds.

       2. Increasing Heat- 

          

           The heat is constantly increasing on the earth. Scientists believe that after 100 million years from today, our sun will be 10% brighter and warmer than today. After 400 million years, the heat will increase so much that the sea water will turn into steam. After 450 million years, the Earth will turn into a big desert like Mars. And the sun must have taken such a terrible form that Mercury, Venus and our moon would have ended.

        3. Earth is not perfect sphere- 

             

            Since childhood we have been taught that the Earth is round, but you might not know that the Earth is not completely round. It is a little flat on its pole. Or you can say that there is a little bit more round in the middle. Actually, the Earth rotates on its orbit towards the equator at such a speed that the Earth has come. Like a ball hit hard. Do you know Mount Everest is the highest mountain on earth. Because the height of the mountains is measured from the surface of the sea. If we measure its height from the womb of the earth, then Mount Chimborazo is the highest mountain on the earth.

        4. Longest mountain range- 

             Do you know what is the longest mountain range in the world? The answer from most of you will be the Andes Mountain Range but this is not the case. Actually only 10% of the world's longest mountain range is visible to us. And the rest is in the depths of the sea. We know it as Mid Ocean Ridge System. According to a survey conducted in 1950, its length is 80,000 k.m. And it is 20 times longer than the Andes mountain range.

        5. Geo- Magnetic Reversal- 

             As you may know that the Earth's pole also acts like a magnet. Scientists believe that the Earth keeps turning its magnetic directions. And this will also happen in the coming times. But there is nothing to worry, because it will not have any effect on us. But all the compasses of the world will be disturbed. But whale and dolphin fish will have more trouble because they find their way only with the help of these magnetic waves.

        6. Uneven Gravity- 

            Many of you must understand that gravity is the same everywhere on earth. Let me tell you that there is no such thing at all. Canada's Hudson Bay is one such example. The gravity here is much less than other places of the earth. It is believed that there is not enough mass between the womb and the surface of the earth. Due to which the gravity here is less. In 2009, the gravity of different places of the Earth was measured using a satellite sent to space. In which this place was learned. By the way, this is not the only place on earth. Rather, such irregularities of gravity have been found in many places.

        7. Pangea- 

            Today there are 6 continents on the Earth. But about 300 million years ago, all these continents were the same. Meaning was a piece of land on earth. Which we knew by the name of Pangea. At that time it was spread over 1/3 part of the earth. Later, about 1.65 million years ago, due to the movement in the Earth's tectonic plates, all the continents gradually separated. According to geologists, after 2.5 million years from now, all the continents will be reunited once. And the Pangea will be formed once again.

        8. Hidden Ocean- 

             Scientists have talked about being a hidden sea about 660 km below the ground. It is believed that this sea has 3 times more water than all the seas on the surface of the earth. This water is not liquid. Is in the form of a large blue rock. Which is named Ringwoodite. Some scientists also believe that the sea which exists on the surface of the earth today. They were also like this inside the ground before. But they came to the surface due to geographical activities.

        9. Earth Was Violet- 

             Earth was purple at first. Now you will say that this is happening more now. Darwin says that we were monkeys. And now the Earth has also turned purple. But if some astronomical biologists believe it is completely true. In fact, instead of chlorophyll, the early jive found on earth used to make food with the help of sun rays using a chemical of purple color. This chemical is named retinal. The color of our planet was also purple for this reason. But later the plants which grew on the earth used chlorophyll to make their food. Green chlorophyll can absorb more sunlight than purple chlorophyll. And so it proved more effective.

        10. How Life Started On Earth ? 

             There are millions of livestock of millions of species on earth. But the most intelligent of them, that is, we humans could not yet ascertain from where we came to this earth. Some scientists believe that all the living organisms of the Earth are made up of molecules that were present on Earth at that time. These ANU or Molecules could repeat themselves. Like there is DNA. But these molecules were made on earth or came from a planet far away in the universe. It is not even clear yet. By the way, most scientists claim that these molecules were made with the creation of the Earth. And we are not aliens.
