A caldera.
Wiki User
∙ 11y ago
When a magma chamber partially empties, the remaining magma can solidify and form igneous rocks. This can result in the formation of a volcanic neck, which is a vertical column of solidified magma that remains after the surrounding rock has eroded away. Alternatively, if the magma is expelled through volcanic eruptions, it can form volcanic deposits such as lava flows and pyroclastic materials.

A circular depression that forms when a magma chamber empties and causes the ground to sink?
A circular depression that forms when a magma chamber empties is called a caldera. It is a large volcanic crater made from the collapse of a volcano's mouth.
What is a large semicircular depression that forms when the magma chamber below a volcano partially empties and causes the ground above to sink?
It is a subsidence caldera. Also known as a non-explosive caldera.
What is the difference between magma and magma chamber?
Magma is molten or partially molten rock beneath the earth's surface. A magma chamber is a space, often beneath a volcano, where magma collects.
What do you call the part inside a volcano where magma collects in a pocket?
Lava collects inside a Magma Chamber. "When an erupting volcano empties a shallow-level magma chamber, the edifice of the volcano may collapse into the voided reservoir, thus forming a steep, bowl-shaped depression called a caldera" (Quoted from How Volcanoes Work at http:/wwwzperiodzgeologyzperiodzsdsuzperiodzedu/how_volcanoes_work/Calderaszperiodzhtml)
Mass rock formed when a volcano's magma chamber empties and collapses?
Scientist say the sill and dike help detemine this
What is a large hole in the magma chamber when it empties and collapses?
Caldera
Formed when magma chamber empties and its roof collapses?
Its called a "caldera".

What kind of feature will it form if the the magma chamber empties beneath a composite volcano and then collapses?
It falls down

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.

Is this correct pyroclastic flows from composite cone volcanoes are known as calderas?
No. They are simply called pyroclastic flows. A caldera is a depression formed in the ground when a volcano, usually a composite volcano, collapses as the magma chamber partially empties during an especially violent eruption.
