Not the Civil War -- World War Two. Although more American died in the Civil War, more Americans were killed in WW2. It's a pedantic technicality perhaps, but the Civil War was America's deadliest war, World War II its bloodiest.
The San Andreas Fault is the transform boundary between the North American Plate and the Pacific Plate. During the 1906 San Francisco earthquake the northern section of the San Andreas Fault slipped northward along the fault from San Juan Bautista to Cape Mendocino, a total of 296 miles (477km).
Transform Boundaries. Transform boundaries occur where ANY TWO PLATES are SLIDING ALONGSIDE EACH OTHER. They are not moving toward or away, but rather sliding past each other. A famous transform boundary exists in California, where the Pacific Plate is sliding past the North American plate. In between the two sliding plates at a transform boundary is a FAULT, or crack in the crust between two plates.
