What is the cavity where magma is stored under a volcano called?
This is called the magma chamber.
A chamber underground containing magma?
A magma chamber.
What activity in the magma causes crustal plate movement?
convection currents. Causes the magma to move the earths crust creating plate movement.
The cause of volcanic activity?
Hot springs and Geysers. A geyser is a foundation of water and steam that erupts from the ground. A hot spring forms when groundwater heated by a nearby body of magma rises to the surface and collects in a natural pool.
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.
Why would hydrothermal metamorphism be common around igneous intrusions and active volcanoes?
The magma that forms an intrusion or feeds a volcano provides the heat that drives hydrothermal activity.

What triggers the small earthquakes the occur around a volcano before an eruption?
Increases in seismic activity around a volcano are typically caused by the movement of magma below the surface into a magma chamber. This causes increases in pressure which leads to fracturing to the rock mass around the magma chamber causing small earthquakes. If the pressure continues to build it would ultimately force the volcano to erupt.
What is crevasse and how does it form?
A crevasse is a deep open crack in a glacier. It is formed when a magma chamber under a glacier causes melting and cracking and causes the glacier to slide into the ocean on the magma

Where is the magma in a volcano?
In a magma chamber
How does the magma chamber work?
Magma Chamber: underground pocket of molten rock
What causes a magma chamber to rise?
Magma rises through the crust because it is less dense than the surrounding rock, and due to the enormous pressure inside the earth.
Does an earthquake occur when magma from the magma chamber rises?
That causes some earthquakes, but most earthquakes occur as a result of tectonic plate grinding against each other.
