Earth was formed 4.6 billion years ago from the same nebula cloud of gas and dust that formed the Sun and other planets. Earth back then was very different from Earth now, and it would have been impossible for life to exist on it. The Earth is still changing even today. It has a molten layer, which causes volcanoes to occasionally erupt, and the crust of the planet is constantly moving, sliding over, under, and sideways against itself. Let's look at how the Earth may have become like the planet it is now.
With erupting volcanoes and a constantly moving crust, the Earth is changing even today.
You live here. This is our solar system, in one of the arms of the Milky Way galaxy. When the universe began, around 10 billion years ago, Earth wasn't around. Neither was our solar system. Our solar system, theMilky Way, was formed in a perfectly ordinary place in the universe in the normal way. Solar systems and the planets within them form from the spinning disks of matter. Slowly, the grains of matter come together to form clumps, then boulders, and eventually balls big enough to have their own gravity coalesce. At this point, these clumped matter are calledplanetesimals, which just means a small, irregular-shaped body formed by colliding matter.
Eventually, the planetesimals grew larger by colliding and combining with other bodies of matter. As the planetesimals grew larger, their gravity was greater, and they collected even more matter. Some of the planetesimals began to orbit the main star, our Sun. When they do this, they are considered to be a planet, an astronomical object that orbits a star and does not shine with its own light. Earth formed this way about 4.6 billion years ago and was mostly done in about 10-20 million years, although it still continues to change to this day.

HERE IS UR ANSWER
Starting 6600 million years ago, the stages involve the formation of the core, the formation of the mantle, the formation of oceanic-type crust, the formation of ancient platforms, and consolidation (the present stage) after which there will presumably be no more earthquakes or volcanic activity.
