Question

Quizplus · Accepted Answer

A depression resulting from explosive volcanism or collapse of the magma chamber is called a caldera. A basin is a low-lying area of land surrounded by higher ground, while a crater is a bowl-shaped depression at the top of a volcano. A sinkhole is a depression in the ground caused by the collapse of a surface layer, and a lahar is a volcanic mudflow. Of these options, caldera is the best choice to describe a large depression resulting from explosive volcanism or collapse of the magma chamber.
