Floetz Rocks
in geology, a name applied by Werner and his followers to the Secondary rocks of Germany, because they were supposed to occur most frequently in flat, horizontal beds.
FLOODS are caused by excessive rains, giving rise to an overflow of the rivers; by the bursting of the banks of rivers, lakes, and reservoirs; by the sudden melting of ice and snow; and by irruptions of the sea, produced by high tides, wind storms driving the sea water inland, earthquakes, volcanic outbreaks, and the bursting of sea banks. The felling of forest trees throughout extensive tracts of mountainous country also tends to make the rivers which have their origin there swell rapidly after a heavy rainfall (see FORESTRY); good and complete drainage of land has the same tendency.
