A body of magma that cuts through (and across) adjacent rock. Similar to a secondary vent but it does not strike through the surface. It then hardens and forms rock. It is always younger than the rocks which surround it.

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 is a pluton a dike a lahar a lava flow or a pyroclast?

A pluton is an igneous rock formation formed beneath the Earth's surface. A dike is a vertical or near-vertical geological formation where magma has intruded into pre-existing rock. A lahar is a type of volcanic mudflow made up of water, ash, and other debris flowing rapidly down the slopes of a volcano. A lava flow is the movement of molten rock on the Earth's surface during a volcanic eruption. Pyroclasts are rock fragments ejected during a volcanic eruption, such as ash, lapilli, and volcanic bombs.


What does a volcano look like inside?

Inside a volcano, you would likely find a magma chamber filled with molten rock and gas under immense pressure. The walls may be lined with various types of hardened lava and volcanic rocks. The exact appearance would vary depending on the type of volcano and its activity level.


Is a dike a intrusive ingneouse rock or a extrusive rock ingneouse?

A dike is an intrusive igneous rock. It is a vertical intrusion that is usually associated with a central magma chamber. It is intrusive because it usually does not reach the surface. When a dike does reach the surface, the magma it countains erupts and forms an extrusive lava flow.
