Magma rises through the crust because it is less dense than the surrounding rock, and due to the enormous pressure inside the earth.
Because of the asthenosphere.
True. The magma chamber is a reservoir of molten rock located beneath a volcano. It serves as the source of magma that can rise to the surface during volcanic eruptions. The presence of a magma chamber is a key factor in the volcanic activity of a region.
yes. it goes upward through a 'pipe' that connects to the magma chamber.
This is called the magma chamber.
The magma chamber is a large underground reservoir of molten rock located beneath a volcano. It acts as a source of magma, which can rise to the surface during volcanic eruptions. The pressure and composition of the magma within the chamber influence the type and intensity of volcanic activity. Over time, the dynamics of the magma chamber can lead to the formation of new volcanic features or the alteration of existing ones.
No, an earthquake typically occurs when there is sudden movement along a fault line in the Earth's crust, releasing accumulated stress. The rise of magma from a magma chamber may trigger small earthquakes due to the movement of surrounding rocks, but it is not the direct cause.
A magma chamber.
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
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.
In a magma chamber
Magma Chamber: underground pocket of molten rock
this answer has to do with density if magma becomes less dense than rock it will rise to the top ,for example vegetable oil in water.
