Earth's evolution spans 4.6 billion years, from a swirling cloud of dust and gas to a dynamic planet with continents, oceans, and life, shaped by impacts, volcanism, plate tectonics, and the emergence of biological processes like photosynthesis, constantly changing its surface and atmosphere. Early molten stages cooled, forming a crust, oceans, and an early atmosphere, allowing single-celled life to appear around 4 billion years ago, which then transformed the planet, eventually leading to diverse ecosystems and shifting continents like Pangaea, with ongoing geological and climatic changes continuing today.
