How is a caldera formed?
A caldera is formed when a volcano erupts violently, causing the emptying of the magma chamber below. The ground above the now-empty magma chamber collapses, creating a large bowl-shaped depression. This depression is further shaped by erosion and subsequent volcanic activity, resulting in a caldera.
Very large crater resulting from the collapse of it's walls?
This type of geological feature is known as a caldera, formed when the magma chamber beneath a volcano empties, causing the volcano to collapse inward. Calderas can be several kilometers in diameter and are often characterized by steep walls and a flat floor. Examples of calderas include Yellowstone in the United States and Santorini in Greece.
WHAT IS THE NAME OF A VOLCANO THAT LOOKS LIKE A LARGE DEPRESSION IN THE GROUND?
A volcano that appears as a large depression in the ground is called a caldera. Calderas form when a volcano erupts and the magma chamber beneath it empties, causing the ground above to collapse. One well-known example of a caldera is the Yellowstone Caldera in the United States.
Did Mount Vesuvius form in a caldera?
No, Mount Vesuvius is a composite volcano and its latest eruption was in 1944. Some sources say that in that eruption, Mt. Vesuvius collapsed in a caldera, but it didn't. FYI: A caldera is a volcano that had an extremely explosive eruption that emptied the magma chamber, causing the volcano to collapse in on itself. An example of a caldera is Crater Lake in Oregon.
What is a large circular depression formed at the top of a volcano called?
Caldera.

What forms when a larger volcano collapses it on itself?
It forms a 'caldera'.

When a volcano collapses into itself at its top it forms a?
When a volcano collapses into itself at its top, it forms a large crater called a caldera. Calderas are formed when the magma chamber of a volcano empties during an eruption, causing the summit to collapse inward.
Is Mount st Helen a crater or caldera?
Mount St. Helens is considered a stratovolcano, not a crater or caldera. It erupted in 1980, causing the top of the mountain to collapse and create a horseshoe-shaped crater.
A basin shaped volcanic depression?
A caldera.
What causes a caldera volcano?
A caldera is a depression formed by an extremely large, explosive volcanic eruption. The largest eruptions drain huge amounts of magma from underground, causing the ground above to collapse into the space left behind.
What are the three steps that most occur in the formation of a caldera?
magma chamber beneath the volcano begins to empty due to an eruption or collapse pressure from the volcanic chamber decreases, causing the overlying rock to collapse into the chamber the collapse creates a large depression in the ground known as a caldera.
Is a caldera another name for a magma chamber?
No. A magma chamber is the area under a volcano where molten rock is stored. A caldera is a depression in the ground formed during an exceptionally violent volcanic eruption. A caldera forms when a volcano drains a large volume of magma from the magma chamber, causing the volcano to collapse into the space left behind.
