Question

You can usually tell the difference between a caldera and crater by studying _____.

Answer 1

A crater is the top of a volcano's central vent and is funnel shaped. A caldera is a magma chamber that supplies materials to the volcano and eventually collapses when there's nothing more to supply.

Answer 2

A caldera is a large, usually circular depression at the summit of a volcano formed when magma is withdrawn or erupted from a shallow underground magma reservoir. The removal of large volumes of magma may result in loss of structural support for the overlying rock, thereby leading to collapse of the ground and formation of a large depression. Craters are smaller, circular depressions created primarily by explosive excavation of rock during eruptions.
