Mysteries of Earth:

Let’s know about heaven, our home, the place where our loved ones live: Earth.

Earth is our planet that is full of secrets. Let’s know about its secrets: Earth has four layers. The inner most layer is filled with solid iron, then comes liquid iron, then rocks and magma, and then more rocks.

One more secret is that, the liquid iron on earth produces a magnetic field that keeps our atmosphere in place.

How did our dear planet form?

Once upon a time there was only one tiny ball. But then fundamental forces: gravity, electromagnetism, and strong and weak nuclear forces pulled it apart. Scientists still don’t know how these forces worked. Then the universe began to expand slowly. Atoms formed and the universe cooled down. Then atoms combined and formed hydrogen and helium. Then clouds of hydrogen and helium combined and formed Earth.

How did we come to Earth?

All life on Earth started from water. Many microorganisms started living and reproducing in water. After some years they combined and formed fishes and other ocean organisms. These organisms started laying eggs on land to protect them from predators. Then these new born organisms adapted the land environment and changed into other organisms like us.

Summary:

Dust and gasses formed Our Earth then life began on Earth and here we are now.
