How much do you know about your home? The home that is big enough to be a comfortable place for everyone in the world. Yes, how much do you know about our planet Earth? How old is it?

Our planet is the only place in the solar system that provides the living environment. The air, water, lands and other wonderful things in it have made it unique among other planets.

According to scientists our planet is 4.5 billion years old and so far has been changed in different ways and has become the place that we are living now. It is good to know some facts about our beautiful planet.

This layer of air shields us from the harmful radiations that come from the sun. There are thousands and thousands of interesting things on Earth to know about that cannot be brought here.
