The Formation and Evolution of Early Earth

The video discusses the early conditions of Earth, which was a hot molten mass. Over time, Earth cooled, leading to the formation of continents through processes like cooling, melting, and sedimentation. Initially, Earth lacked continents, oceans, and a developed atmosphere. Some of the oldest rocks, over 3.5 billion years old, are found in places like the Grand Canyon and the Adirondack Mountains.
