High silicate composition in lava leads to increased viscosity, making the lava thicker and less fluid. This results in slower flow rates, which can cause lava to build up around the vent and form steep-sided volcanoes, such as stratovolcanoes. The high viscosity also traps gases, increasing the potential for explosive eruptions when pressure is released. Consequently, the eruptive style is often more violent compared to low-silicate, more fluid lavas.

What are calc silicate gneiss?
Calc-silicate gneisses simply are marbles with an impure composition, in other words, the ones that contain a high amount of silica, which combine with calcium and magnesium to form piroxenes, anfiboles and olivines as well. It often happens in the metamorphism of plataformal sequences where limestones are present.
Igneous rocks that contain many dark silicate minerals and that also are rich in magnesium and iron have a composition that is . ultramafic andesitic basaltic granitic?
Igneous rocks that contain many dark silicate minerals and are rich in magnesium and iron have a composition that is classified as ultramafic. These rocks typically contain high amounts of olivine and pyroxene, making them dense and dark in color. Examples include peridotite and komatiite, which are formed from very high-temperature magmas.
What is basic composition on mercury?
Mercury is composed mostly of iron and silicate materials, with a metallic core making up about 42% of its mass and a rocky mantle and crust. It also contains smaller amounts of volatile compounds like sulfur and water ice. Overall, Mercury's composition is characterized by a high density and a large iron core relative to its size.
Peridotite is composed almost entirely of dark sillicate mineralsits chemical composition is referred to as?
Peridotite is composed almost entirely of dark silicate minerals, primarily olivine and pyroxene. Its chemical composition is referred to as ultramafic, containing high levels of magnesium and iron.
is gneiss a silicate rock?
Yes, gneiss is a type of metamorphic rock that typically contains silicate minerals. It is characterized by its banded or foliated appearance, which results from the recrystallization of pre-existing rocks under high temperature and pressure. The mineral composition of gneiss often includes quartz, feldspar, and mica, all of which are silicates.
Composition of cement?
Cement is made , not found. Portland cement, for instance, is made by heating limestone and clay to high temperature (1500 degrees Celsius) and crushing the result to a powder for sale.
What is alkaline silicate glass?
Alkaline silicate glass is a type of glass that contains sodium and/or potassium ions in its composition. It is characterized by its high chemical durability and resistance to water. Alkaline silicate glass is commonly used in products like glass containers, fiberglass, and some types of windows.

Igneous rocks that contain many dark silicate minerals and that also are rich in magnesium and iron have a composition that is .?
Igneous rocks that are rich in dark silicate minerals and contain high levels of magnesium and iron are classified as mafic rocks. These rocks typically include basalt and gabbro, characterized by their darker color and denser composition. The term "mafic" is derived from the minerals magnesium and ferric iron, which are predominant in these types of rocks.
Viscosity is a fluids resistance to?
Viscosity is a fluid's resistance to flow. It is a measure of the fluid's internal friction and is influenced by the fluid's composition and temperature. Fluids with high viscosity flow more slowly than fluids with low viscosity.
How does hummidity affect flow rate?
High humidity can decrease the rate at which water evaporates from a surface, which can affect the flow rate in a system reliant on evaporation like in cooling processes. On the other hand, in systems like pneumatic conveying where moisture can cause particles to stick together, high humidity can increase flow resistance and reduce flow rates.
