“According to pioneering microbiologist Lynn Margulis, "fully 10 percent of our own dry body weight consists of bacteria, some of which, although they are not a congenital part of our bodies, we can't live without." In fact, a healthy human body has more bacterial cells than animal cells (bacterial cells are far smaller). Our own bodies are in some ways microcosms of the biosphere as a whole.”
Marcia Bjornerud, Reading the Rocks: The Autobiography of the Earth

“With each integer on the Richter scale, there is a tenfold increase in the number of earthquakes that occur annually. On average, there is one magnitude 8 event, ten magnitude 7 events, a hundred magnitude 6 events, and so on, each year. If we consider this from an energy standpoint, the smaller earthquakes account for a significant fraction of the total seismic energy released each year. The one million magnitude 2 events (which are too small to be felt except instrumentally) collectively release as much energy as does one magnitude 6 earthquake. Although the larger events are certainly more devastating from a human perspective, they are geologically no more important than the myriad less newsworthy small ones.”
Marcia Bjornerud, Reading the Rocks: The Autobiography of the Earth

“Little by little, over more than two centuries, the local stories told by rocks in all parts of the world have been stitched together into a great global tapestry - the geologic timescale. This "map" of Deep Time represents one of the great intellectual achievements of humanity, arduously constructed by stratigraphers, paleontologists, geochemists, and geochronologists from many cultures and faiths. It is still a work in progress to which details are constantly being added and finer and finer calibrations being made.”
