How the Earth Was Made is a documentary television series produced by Pioneer Productions for the History Channel.It began as a two-hour special exploring the geological history of Earth, airing on December 16, 2007.
The geological time scale (GTS), as defined by international convention, [3] depicts the large spans of time from the beginning of the Earth to the present, and its divisions chronicle some definitive events of Earth history. Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar ...
Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left over from the formation of the Sun, which also created the rest of the Solar System. Initially, Earth was molten due to extreme volcanism and frequent collisions with other bodies.
Amasia Supercontinent: Earth's Geologic Past Shapes Our Understanding Of Future Before it split into the continents we know today, Earth was home to just a single landmass, or "supercontinent ...
Earth's atmosphere and oceans were formed by volcanic activity and outgassing. [43] Water vapor from these sources condensed into the oceans, augmented by water and ice from asteroids, protoplanets, and comets. [44] Sufficient water to fill the oceans may have been on Earth since it formed. [45]
According to evidence from radiometric dating and other sources, Earth formed about 4.54 billion years ago. [7] [8] [9] The current dominant theory of planet formation suggests that planets such as Earth form in about 50 to 100 million years but more recently proposed alternative processes and timescales have stimulated ongoing debate in the planetary science community.
