Geologic time shown in a diagram called a geological clock, showing the relative lengths of the eons of Earth's history and noting major events The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale , a system of chronological measurement based on the study of the planet's rock ...
The history of geology is concerned with the development of the natural science of geology. Geology is the scientific study of the origin, history, and structure of the Earth . [ 1 ]
Historical geology or palaeogeology is a discipline that uses the principles and methods of geology to reconstruct the geological history of Earth. [1] Historical geology examines the vastness of geologic time, measured in billions of years, and investigates changes in the Earth , gradual and sudden, over this deep time .
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 ...
Sir Charles Lyell first published his famous book, Principles of Geology, [6] in 1830. This book, which influenced the thought of Charles Darwin, successfully promoted the doctrine of uniformitarianism. This theory states that slow geological processes have occurred throughout the Earth's history and are still occurring
1830 – Sir Charles Lyell publishes book, Principles of Geology, which describes the world as being several hundred million years old; 1837 – Louis Agassiz begins his glaciation studies which eventually demonstrate that the Earth has had at least one ice age; 1841 – August Breithaupt, Vollstandiges Handbuch der Mineralogie
the geological history of the Earth itself; genres of history, such as Geographical history – the influence of geographical factors on human history, History of geodesy – development of the discipline concerned mainly with the Earth's overall shape, orientation in space, and gravitational field), History of geography – changes in human ...
The geological time scale encompasses the history of the Earth. [13] It is bracketed at the earliest by the dates of the first Solar System material at 4.567 Ga [14] (or 4.567 billion years ago) and the formation of the Earth at 4.54 Ga [15] [16] (4.54 billion years), which is the beginning of the Hadean eon – a division of geological time.
