14) Another term for a volcanic mudflow is a 15) Describe a pyroclastic flow.

Volcanic mudflows, often called lahars, are incredibly dangerous and can occur when volcanic activity melts ice or heavy rainfall mixes with loose volcanic debris. These flows can travel swiftly down river valleys, carrying with them boulders, trees, and anything else in their path, posing a serious threat to communities located near volcanoes. A pyroclastic flow is a fast-moving current of hot gas and volcanic matter—typically exceeding 1,000 degrees Celsius (1,832 degrees Fahrenheit)—that rushes down the slopes of a volcano during an explosive eruption. These flows can travel at speeds of over 700 km/h (about 435 mph), making them one of the deadliest volcanic hazards; they can obliterate everything in their path due to their intense heat and speed.
