Physical science, the systematic study of the inorganic world, as distinct from the study of the organic world, which is the province of biological science.Physical science is ordinarily thought of as consisting of four broad areas: astronomy, physics, chemistry, and the Earth sciences.29 voted in favour (88% of votes cast); 4 voted against; no abstentions 60%) agreement by the AWG and its parent bodies (successively the SQS and ICS) and ratification by the Executive Committee of the International Union of Geological Sciences.The success of any such proposal is not guaranteed.

The evidence for the Anthropocene is examined in detail, ranging from chemical signals arising from pollution, to physical changes to the landscape associated with urbanisation and biological changes associated with species invasion and extinctions.
Each of these is in turn divided into fields and subfields.
This article discusses the historical development—with due attention to the scope, principal concerns, and methods—of the first three of these areas.
The scale, manner and rate of global environmental change is placed within the context of planetary processes and deep geological time, allowing the reader to appreciate the scale of human-driven change to the Earth system, and compare the global transition taking place today with major transitions in Earth history.
Key aspects of the geological background are explained, providing an authoritative review of the Anthropocene for graduate students and academic researchers across a broad range of scientific, social science and humanities disciplines.
