When magma heats underground water the result may be?
When magma comes in contact with underground water, it creates hot springs, or geysers.
What two things does the appearance of a volcano depend on?
One factor that influences a volcanic eruption is the composition of the lava; the thicker the lava, the more explosive the eruption. Another factor is the level of pressure that forces magma up a pipe or vent; the higher the pressure, the more violent the eruption.
What is the main lava chamber in the neck of a volcano?
A magma chamber in a volcano is a pool-like container of liquid rock just below the earth underground. It is constantly under tremendous pressure, and with enough time, it can start fracturing rock to make places for magma to escape.
The process in which a rock changes as a result of heat generated from magma?
contact metamorphism
What are the Deccan traps?
The Deccan Traps is a plateau in India. It formed from cracks or holes (called vents) in the crust of earth. So, the molten rocks called magma emerged out from the mantle on to the surface of earth through these vents. This magma then got cooled and solidified to form igneous rocks. Large volumes of magma spread over a large surface area of earth produced a high level land called plateau, extending over several hundred square kilometres.
What type of volcanic event occurs when a large amount of water comes in contact with a magma chamber?
a crater lake forms
Which would you expect to cause the greatest amount of contact metamorphism an intrusion of basaltic magma or an intrusion of rhyolitic magma?
Basaltic magma
What happens when there is a lot of water present in the magma?
The large amount of water would increase the amount of magma, making it easier to melt rocks. The water vapor would help the magma cause explosive eruptions.
What happens when Magma with a large amount of dissolved gases tends to be?
very explosive.
What happens if there is a lot of water present in the magma of a volcano?
The large amount of water would first increase the amount of magma, as it make it easier to melt rocks. Then the water vapor would help cause explosive eruptions.
What has to happen to magma for glass to form?
The magma has to crystalize...
Which type of volcano has explosive eruptions due to thick magma which contains large amount of pressurized gas?
the stratovolcano
Which type of volcano has explosive eruptions due to thick magma which contains a large amount pf pressurized gas?
the stratovolcano
Are geological features created by rhyolitic magma Rhyolitic magma promotes eruptions?
Lava domes are large geological features created by rhyolitic magma. Rhyolitic magma promotes plinian eruptions. Plinian eruptions can happen very quickly and shoot lave several miles into the air.
Do volcanic bombs have a large amount of silica?
Not necessarily. Volcanic bombs may be formed from any composition of magma from basaltic to rhyolitic.
How are magma and igneous rock compositions categorized?
They are classified by the amount of silica vs the amount of alkalies are in the rocks or magma.
How do contact metamorphic rocks form?
its forms by contact with hot magma
