Question
Earth formed from interstellar dust and debris in a process called accretion. During accretion, the gravitational compression of the emerging mass elevated the temperature, and with additional heat supplied by the decay of radioactive elements, the proto-Earth became a hot molten mass that stratified according to density. As a result, Earth has a core rich in iron and nickel and a crust made up of silicon, magnesium, and iron.

Over time, the molten Earth began to cool and solidify, forming a solid outer crust. The process of cooling also caused the heavier elements like iron and nickel to sink towards the center, creating the Earth's core. This process is known as differentiation.
As the Earth continued to cool, its surface began to solidify into rocky plates, which eventually formed the continents and oceans we see today. The movement of these plates, powered by the heat generated from the Earth's core, created the dynamic processes of plate tectonics, which continue to shape the Earth's surface.
The Earth's atmosphere also developed during this time, as gases released from volcanic activity formed a primitive atmosphere composed mainly of carbon dioxide, water vapor, and nitrogen. As the Earth cooled further, water vapor began to condense and form the oceans, while plants and other life forms began to evolve and produce oxygen through photosynthesis.
Today, Earth is a dynamic and ever-changing planet, with a diverse and complex system of geology, atmosphere, and life. Its formation and evolution are a testament to the natural processes that have shaped our planet over billions of years.
