Volcanoes are made up of several parts. The magma chamber is a pocket of molten rock under the volcano where magma builds up. The vent is the path through which magma travels from the magma chamber to Earths surface. The crater is where lava is ejected from the volcano. After eruption, lava, ash and rock often settle on the sides of the volcano, forming layers called strata. These layers build up over time as volcanoes take on a mountain-like shape.Which of the following best describes the process by which magma reaches Earths surface during a volcanic eruption?

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Volcanoes are made up of several parts. The magma chamber is a pocket of molten rock under the volcano where magma builds up. The vent is the path through which magma travels from the magma chamber to Earth’s surface. The crater is where lava is ejected from the volcano. After eruption, lava, ash and rock often settle on the sides of the volcano, forming layers called strata. These layers build up over time as volcanoes take on a mountain-like shape.Which of the following best describes the process by which magma reaches Earth’s surface during a volcanic eruption?

A	Magma builds up in the strata until it is released through the vent crater to form lava.
B	Magma builds up in the vent until it is released through the magma chamber at different strata.
C	Magma builds up in the crater then travels through the strata until it is released through the vent.
D	Magma builds up in the magma chamber then travels through the vent until it is released through the crater.

Explanation:

Detailed explanation-1: -Main Vent: A volcano’s main vent is the weak point in the Earth’s crust where hot magma has been able to rise from the magma chamber and reach the surface.

Detailed explanation-2: -A volcano is an opening in a planet or moon’s crust through which molten rock and gases trapped under the surface erupt, often forming a hill or mountain.

Detailed explanation-3: -Conduit-The channelway or passage, which may be pipe-shaped, that brings magma from the reservoir or chamber to the vent at the surface where it is erupted. Magma-Molten rock beneath Earth’s surface capable of intrusion and extrusion.

Detailed explanation-4: -Magma is molten rock that is located under the surface of the Earth. A magma chamber is usually located far beneath the surface of the Earth where an oceanic plate is driven down into the mantle by a continental plate. The oceanic plate melts as it desends into the upper layer of the mantle.
