GEOLOGY

Detailed explanation-1: -A caldera is a depression created after a volcano releases the majority of the contents of its magma chamber in an explosive eruption. Without any structural support below, the land around the erupting volcanic vent or vents collapses inwardly, creating the bowl-shaped caldera.

Detailed explanation-2: -The crater is the bowl shaped opening located at the top of the volcano. The crater is also the steep sided walls made of hardened lava that surround the main vent.

Detailed explanation-3: -Vent. Vent-The opening or place at Earth’s surface through which magma, rock fragments, and/or volcanic gases are emitted.

Detailed explanation-4: -A caldera is a depression created after a volcano partially collapses after releasing the majority of its magma chamber in an explosive eruption.

Detailed explanation-5: -A crater is a bowl-shaped depression, or hollowed-out area, produced by the impact of a meteorite, volcanic activity, or an explosion.
