Which of the following general statements about volcanoes and volcanism is false? Pyroclastic fall deposits may cover vast regions if the eruption is large enough. Pyroclastic flows are formed from extremely hot, rapidly moving lava. Volcanic ash consists of tiny particles of rock and shards of glass. Lahars tend to follow river valleys and can extend tens of kilometers away from their volcanic source. Because cinder cones are structurally weak, lava flows may emerge laterally from the base of the volcanic cone.
