a compound of silicon and oxygen (SiO2)
You can say that it is low in silica. -I had this problem in my science class ^_^
The silica content of the Earth's crust beneath the oceans is typically lower compared to the crust beneath continents. This lower silica content results in a type of magma known as basalt, which is commonly associated with oceanic volcanoes like those found along mid-ocean ridges.
Any metrial or thing which containts silica in it is call silica content..
where can silica mineral can be found
Yes. Silica is everywhere.
The chemical compound silica is an oxide of silicon .In other words; silicon is in silica.
Calcite does not contain any silica. It is a carbonate mineral.
lava rich in silica
Sand usually contains abundant silica, but it generally is not pure silica.
You can buy Silica Gel from: http://www.silicagelpackets.com/ They have just about anything Silica Gel related; Loose Bulk Silica Gel, Silica Gel Packets, Canisters, Dehumidifiers, Flower Drying Silica Gel, etc.
Rhyolite is silica-rich, containing over 70% silica. It is an extrusive igneous rock with a fine-grained texture that forms from the rapid cooling of magma rich in silica content.
Krakatoa is silica-rich, meaning it contains a high amount of silicon dioxide (silica) in its composition. This high silica content is associated with explosive volcanic eruptions due to the interaction between silica and magma.
