What are 3 substances that affect the explosiveness of volcanic eruptions?
Water, gas content, and silica content are three substances that can affect the explosiveness of volcanic eruptions. Higher water content can generate more explosive eruptions, whereas higher gas content and higher silica content can also contribute to increased explosiveness.
Does the lava that forms shield volcanoes probably have a lot of silica or water in it?
No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.
Do shield volcanoes have a lot of silica or water?
Shield volcanoes have low silica content and low water content in their magma. This results in fluid lava flows that spread out over large distances, creating the characteristic broad, gently sloping shield shape.
How does the high water content affect the explosiveness of volcanoes?
High water content can increase the explosiveness of volcanoes because it promotes the formation of steam and gas bubbles in magma, building up pressure that can lead to explosive eruptions. When water interacts with magma, it can cause rapid expansion and fragmentation of the magma, creating explosive eruptions with ash clouds and pyroclastic flows.
Which one of the following types of volcanoes would be the most explosive a volcanoes that contain small amounts of water b volcanoes that have thin magna c ones that contain small amounts of carbo?
D. Volcanoes that have large amounts of silica
What is the relationship between the amount of gases in magma and the explosiveness a volcanic eruption?
The more gases, water vapor and silica there is in magma the bigger the explosiveness of a volcanic eruption.

What type of volcano has magma that contains large volumes of gases but not silica and water?
A volcano with magma that contains large volumes of gases but not silica and water is typically a shield volcano. These volcanoes have low viscosity magma that allows gases to escape easily, resulting in relatively gentle eruptions characterized by lava flows.
What forms from lava that is higher in water and silica content than lava that forms shield volcanoes?
Lava that is higher in water and silica content tends to be more viscous and can lead to explosive eruptions. This type of lava forms stratovolcanoes, also known as composite volcanoes, which are characterized by steep slopes and alternating layers of lava flows, ash, and volcanic rocks. Examples include Mount St. Helens and Mount Fuji.
What is the silica and water content of mt Cleveland?
Mount Cleveland, a stratovolcano in Alaska, typically has a high silica content in its volcanic rocks, which is common for volcanoes in the Aleutian arc. The specific silica content can vary depending on the eruption. The water content in Mount Cleveland's magma is also high, contributing to its explosive eruptions.
Does silica reacts with water?
Silica is in soluble in water.
