They also helped　　15）build the vast network of canals and railroads that crisscrossed the continent and linked important trade centers essential to industrial growth. Factories also offered a reprieve from the backbreaking work and financial unpredictability associated with farming.

Much of our information about climate in the more recent periods of geologic history es from the fossil record, because we have a reasonably good understanding of the types of environment in which many fossil organisms flourished. The scarce fossils　　5) of the Proterozoic, mostly singlecelled bacteria, provide little evidence in this regard. However, the rocks themselves do include the earliest evidence for glaciation, probably a global ice age.　　The inference that some types of sedimentary rocks are the result of glacial activity is based on the principle of uniformitarianism, which posits that natural processes now　　10) at work on and within the Earth operated in the same manner in the distant past. The deposits associated with presentday glaciers have been well studied, and some of their characteristics are quite distinctive.
