The Earth in Context: A Guide to the Solar System (Springer-Praxis Series in Astronomy and Space Sciences) (Springer Praxis Books) - Softcover

Inhaltsangabe

Awareness of the environment was stimulated by the 'Earthrise' pictures taken by the first Apollo crew to orbit the Moon. By sending spacecraft to other planets we've gained insights into the early history of our own planet. Comparative planetology is a science that has been facilitated by the Space Age. Comparative planetology highlights both similarities and differences. Processes tend to manifest themselves in different ways. Usually the term 'vulcanism' conveys an impression of red hot lava erupting from a fissure, or streaming down the flank of a volcano. This may have been the case on Venus and Mars, but on some of the Moons of Jupiter and Saturn the lava is cryogenic fluid. There are geysers of sulphurous gases on Jupiter's moon Io and at the far edge of the solar system on Neptune's moon Triton, there are Nitrogen geysers. Our concept of vulcanism has been broadened by comparative planetology. 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.
