How did the earth form?

Hint: In this question we have to see the formation of earth. For this we will have to go about 4.5 million years ago because the age of earth is around 4.5 million years. Now we will see in the below explanation how earth was formed and what it has on its surface.

Complete answer:
Earth was formed around 4.5 million years ago when it was settled into its current form. Swirling gas and dust were pulled in to form earth by gravity. By this process the earth was formed. Earth has its central core and solid crust.
As we all know that earth is a terrestrial planet. Earth has mountains, rivers, valleys, plains and so many more things. Earth has its atmosphere around it. The atmosphere of earth is made up of nitrogen mostly and it has oxygen also for humans and animals to breathe. The atmosphere of earth protects us from coming meteoroids because it breaks them before they hit the earth.
Result- Hence, from the above explanation we can clearly understand the formation of earth and how it looks like now.

Note: Earth is the only planet that we know so far which has life. Earth was formed by the pull of gravity. As we have come to know about swirling gas and dust in the above explanation. Now, we will understand what is swirling gas and dust. As we know that swirling means to move in a twisting pattern. So, swirling gases are those which move in a twisting pattern. Dust is made of fine particles of solid matter. These come from various sources such as volcanic eruption, soil lifted by the wind and pollution.
