What is the large circular depression at the top of a volcano that forms when the roof of the magma chamber collapses?
The large circular depression at the top of a volcano that forms when the roof of the magma chamber collapses is called a caldera. Calderas can be huge in size and are formed during explosive volcanic eruptions or when the magma chamber empties and the summit collapses into the void left behind.
A caldera is a depression in a volcanic mountain A caldera may form when?
The mountain collapses into an emptied magma chamber
When a cone collapses into the magma chamber what is the depression called?
When a cone collapses into the magma chamber, the resulting depression is called a caldera. Calderas form due to the collapse of the ground following a volcanic eruption when the magma chamber is emptied. This can create a large, basin-like structure that may eventually fill with water or become the site of new volcanic activity.
Mass rock formed when a volcano's magma chamber empties and collapses?
A mass rock is formed when a volcano's magma chamber empties and the overlying rock collapses into the empty chamber. This creates a steep-walled depression or caldera at the volcano's summit. It is a common feature of collapsed volcanoes.
What happens to create a caladera?
A caldera is formed when a volcano collapses into the emptied magma chamber below after a major eruption, leaving a large, basin-shaped depression. This collapse can be triggered by the withdrawal of magma during an eruption or by the weight of material above the magma chamber becoming unstable.

Does a caldera form when a magma chamber's roof collapses?
yes, I think so. because, very large volume of magma is ejected and then magma chamber can't support the volcano above it. then the volcano begins to sink into the earth.magma chamber empties and a new collapsed depression occurs.
How is a caldera different from a dike?
A caldera is a circular depression formed when a subterranean magma chamber collapses because it has emptied.. A dike is a vertical sheet of magma with a great lateral extent.

What is a large hole in the magma chamber when it empties and collapses?

When the roof of a magma chamber collapses?
When the roof of a magma chamber collapses, it can lead to the formation of a caldera, which is a large depression resulting from the ground sinking after the magma is expelled during a volcanic eruption. This collapse occurs when the magma is significantly depleted, causing the overlying rock to lose support and fall inward. The event can also trigger secondary volcanic activity, including the emergence of new vents and the release of gases. Such collapses can dramatically alter the landscape and affect local ecosystems.
Why does a caldera happen?
the roof of the magma chamber collapses forming caldera
What forms when the top or side of a volcano collapses into the magma chamber?
