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.
Why does more silica make lava flow slow?
In rocks lava with a high silica content the silica starts to form a covalent network, where the silicate groups continously bond together.
How does heat affect lava flow?
Heat effects the flow rate of lava because the hotter the lava is, the less viscous it is which allows it to flow faster than if it had a slow flow rate. If it has a low temperature, then the flow rate will be much slower because it has a high viscosity.
How does magma composition and the resulting eruption affect the form of a volcano?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
What is the viscosity of magma in a pyroclastic flow?
In a pyroclastic flow, the magma would almost always be considered high-velocity. The velocity and strength of the magma is a result of its chemical composition.
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 a A high temperature silicate with a name that is based on its color?
leucite
How do impermeable surfaces affect infiltration?
A rock that has high porosity is not permeable if the pores or fractures are not connected. The larger and better shorted the particles are, the more permeable the rock or sediment tends to be. Because of this characteristic composition, clay is essentially impermeable, which means that water cannot flow through it.
Can high flow exhaust affect egr valve?
If it is a back pressure regulated type of egr, yes.
Why is that high variation of protein composition in membrane?
high variation of protein composition in membrane?
Are diamonds non silicate or silicate?
No it is a nonsilicate mineral because it is formed from only carbon and not silicate.
What is fermiculite?
Fermiculite is a silicate mineral which is hydrous and high expands during heating.

How can the composition of magma affect the way volcano erupts?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
