However, to draw this conclusion we have to assume that the rate of cratering has been the same in the past as it is now.And there are now good reasons for thinking that it might have been quite intense in the past, in which case the craters do not indicate an old age at all (see below).Being ancient, the C-14 content has long since decayed away and that makes it useful in "zeroing" laboratory instruments. Hovind would take the trouble to do a little reading from something other than creationist publications he would not make such an outrageous statement.It's just one of the tricks that have been used to make the work a little more precise. I believe he has confused the use of index fossils with evolution.One creationist editor, who is more mellow than his unfortunate statement suggests, phrased the argument thus: Unfortunately the geologists date the rocks as the paleontologists tell them to. That passage might have come out of one of Henry Morris' books, except that Morris usually avoids crude slander. Hovind is not aware of the fact that by 1815 the broad outlines of the geologic column from Paleozoic times onward had been worked out by people who were mostly geologists.
The term geophysics sometimes refers only to the geological applications: Earth's shape; its gravitational and magnetic fields; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation.
There is perhaps no greater attack on science than Young Earth creationism (YEC).
This article collects evidences that place a lower limit on the age of the Universe beyond the 6,000 to 10,000 years asserted by most Young Earth creationists (YECs) and the literalist Ussher chronology.
Geophysics is a highly interdisciplinary subject, and geophysicists contribute to every area of the Earth sciences.
To provide a clearer idea of what constitutes geophysics, this section describes phenomena that are studied in physics and how they relate to the Earth and its surroundings.
The first magnetic compasses were made from lodestones, while more modern magnetic compasses played an important role in the history of navigation. Isaac Newton applied his theory of mechanics to the tides and the precession of the equinox; and instruments were developed to measure the Earth's shape, density and gravity field, as well as the components of the water cycle.
