When the top of a volcanic mountain collapses it forms a what?
When the top of a volcanic mountain collapses, it forms a volcanic crater or caldera. This creates a bowl-shaped depression at the summit of the volcano.
What is a mountain built from magma?
A mountain built from magma is called a volcanic mountain. It forms when magma from beneath the Earth's surface erupts through a vent or fissure, cools, and solidifies to create layers of volcanic rock and ash over time. Examples include Mount St. Helens in the United States and Mount Fuji in Japan.
What crater forms when a volcano erupts?
A divergent
When a volcano erupts quietly what kind of mountains forms?
a shield volcano
Why does a mountain build around a volcano when a volcano erupts many times?
A mountain forms around a volcano because each volcanic eruption can release large amounts of lava and other volcanic materials, which can accumulate over time and gradually build up the height and size of the volcano. With each eruption, new layers of lava and ash are added to the existing structure, creating a larger and taller mountain over time.
What is magma the erupts onto the surface of the volcano c?
Magma that erupts onto the surface of a volcano is called lava. When magma rises from beneath the Earth's crust and reaches the surface, it flows out during a volcanic eruption. Lava can vary in composition, temperature, and viscosity, affecting its behavior and the type of eruption that occurs. Once it cools and solidifies, it forms volcanic rock, contributing to the structure of the volcano and the surrounding landscape.
When a volcano erupts and forms new land does old land disappear?
No
The melted rock that forms a volcano is called what?
The melted rock that forms a volcano is called magma when it is beneath the Earth's surface. Once it erupts and reaches the surface, it is referred to as lava. As lava cools and solidifies, it can create various volcanic landforms, including mountains and islands.
How can rock form when a volcano erupts?
The rock forms over a cooling process.
What does a volcanic crater form?
It forms by volcanic activity in the vent of a volcano.
A mountain that forms when layers of lava and ash erupt and build up is a what?
what is mountain formed from layers of lava and ash
What is the opening around which a volcano forms?
A volcanic vent.
