GEOLOGY

Detailed explanation-1: -A large hole left by the collapse of a volcanic mountain is called a crater.

Detailed explanation-2: -A caldera is a large depression formed when a volcano erupts and collapses. During a volcanic eruption, magma present in the magma chamber underneath the volcano is expelled, often forcefully.

Detailed explanation-3: -Calderas are collapse features that form during large-volume volcanic eruptions when the underlying magma chamber is partially emptied and the ground above it subsides into it.

Detailed explanation-4: -The Yellowstone Caldera, located in Yellowstone National Park in the U.S. state of Wyoming, is the result of the Yellowstone Supervolcano. This enormous volcano complex last erupted about 640, 000 years ago. The Yellowstone Caldera is more than 72 kilometers (45 miles) long.

Detailed explanation-5: -Caldera: In some volcanoes, the summit of the volcano blows up during a violent explosion resulting in the formation of a large depression called a Caldera. Some calderas may have been formed by the collapse of the summit portion. Calderas are occupied by large lakes. The lake in the caldera is called the crater lake.
