Question

Quizplus · Accepted Answer

Explosive or voluminous eruptions can cause the walls of the volcano's magma chamber to collapse inward, producing a broad depression known as a caldera. A crater is a depression at the summit of a volcano, often produced by smaller explosions or collapse events. A lahar is a type of volcanic mudflow caused by the mixing of volcanic debris with water. A fissure is a crack or opening in the Earth's surface, often associated with volcanic activity but not a type of depression or collapse feature produced by eruptions.
