Our planet consists of layers under earth. They are Crust, Upper Mantle, Lower Mantle, Outer Core, and Inner Core.
I would like to talk now about the crust. The crust has land and water. the land is divided by continents. They are: Asia, Europe, Africa, North America, South America, Oceania, and Antarctica. All of them have countries except Antarctica.
Most of the countries known and famous are U.S, U.K, Australia, China, Russia, New Zealand, and Canada. There are lots more than I just said. There are 195 countries!!!
