"Evolution of Earth: 7 Ancient to Modern Transformations"
The Earth has undergone significant changes from ancient to modern times, including the transformation of its atmosphere from hydrogen/helium to nitrogen/oxygen, the development of plate tectonics, the lengthening of its day due to tidal forces, the outspiraling of the Moon to its current distance, a decline in crater-causing impacts, the emergence and transformation of life, and the increasing solar luminosity, which will eventually lead to the boiling away of Earth's oceans in 1-2 billion years.
