What kind of magma produces a quiet volcanic eruption?
A. Magma that is rich in Silica
B. Magma that is Fluid
C. Magma that is low in Iron
D. Magma that is low in Silica••
Correct me
I am trusting you Alexa, I just hope it's D!!
D. Magma that is low in Silica••
yall need to stop using ur real names... teachers check this website
You are correct.
What is the answer? lol
ITS D CANDLE NOT A
just read the textbook thingy and it tells you but yes it is D
The correct answer is D. Magma that is low in Silica.
To understand why this answer is correct, we need to first understand different types of magma compositions and how they affect volcanic eruptions.
Magma is a molten rock mixture that is found beneath the Earth's surface. It is formed by the partial melting of the Earth's mantle or crust. Magma compositions can vary depending on the concentration of different elements and minerals present in the molten rock.
Silica is one of the main components of magma and plays a crucial role in determining the eruptive characteristics of a volcano. Silica content in magma affects its viscosity or ability to flow. Magma with high silica content has a high viscosity, making it thicker and more resistant to flow. On the other hand, magma with low silica content has low viscosity, making it more fluid and easier to flow.
When magma with low silica content is erupted, it tends to flow more easily, allowing gases to escape. This results in a relatively gentle or quiet volcanic eruption. The low viscosity of the magma allows gas bubbles to rise and escape without building up pressure to cause explosive eruptions.
Conversely, magma with high silica content has a higher viscosity, which traps gases within the magma, leading to the buildup of pressure. This can result in explosive volcanic eruptions, where the trapped gases are rapidly released, causing the magma to explode and eject ash, rocks, and volcanic debris into the air.
So, magma that is low in silica (option D) produces quiet volcanic eruptions, while magma that is rich in silica (option A) tends to produce explosive eruptions.
Therefore, the correct answer is D. Magma that is low in Silica.
