Question

Quizplus · Accepted Answer

Pyroclastic flows are extremely hot, fast-moving currents of gas and volcanic matter that have been known to travel as fast as 450 miles per hour. They are made up of a mixture of superheated gases and ash, and can reach temperatures of 1,830°F. The greatest danger comes from being incinerated by the hot gas and entrained magma, making option B the correct answer. While being smothered by hot gases and ash or buried in ash are also possible dangers, they are not as immediate or severe as being incinerated. The final option stating that pyroclastic flows move slowly and can be avoided is entirely incorrect, as they are some of the fastest-moving and most deadly natural phenomena on Earth.
