The Earth in Context: A Guide to the Solar System tells a tale of
scientific discovery, with two interwoven strands - one tracing the
development of understanding the Earth's geological history, and the
other placing this in the context of processes at work on the other
planets of the solar system. Although planetology is assigned half of
the text, the primary focus of the book is the Earth. It is discussed in
two parts, the first summing up our knowledge of the Earth as it is
today and the other considering it as it was long ago.
