Did the earth always look as it does today?

 No,since its origin about 4.8billion years ago, our planet has undergone a lot of changes. The initial ball of fire 🔥cooled down and the surface slowly turned solid. Today, we know that the earth's crust is divided into several plates, which move continuously. Entire continents have been displaced and mountains, islands, and new seas have been formed or have disappeared. Even the floor and the fauna have evolved over time. Many species become extinct and new ones have discovered. This development of the earth over billions of years is known as the history of the earth.
