    History of Earth

    Overview of Earth's history

    For more detail of the geological history of Earth, see Geological history of Earth.

    For more detail of the biological history of Earth, see History of life.

    The natural history of Earth concerns the development of planetEarth from its formation to the present day.[1][2] Nearly all branches of natural science have contributed to understanding of the main events of Earth's past, characterized by constant geological change and biological evolution.

    The geological time scale (GTS), as defined by international convention,[3] depicts the large spans of time from the beginning of 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 nebula.[4][5][6] Volcanic outgassing probably created the primordial atmosphere and the
