What is Krakatoa a silica rich or a silica poor?

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.


What minerals make up a obsidian?

salt, silca, and grain


What are the ingredients of igneous rock?

Igneous rocks are formed from the cooling and solidification of magma or lava. They typically contain minerals such as quartz, feldspar, mica, and pyroxene, which crystallize as the molten rock cools. The exact composition of an igneous rock will depend on factors such as the original magma composition, cooling rate, and any subsequent processes that may have altered the rock.


Why do magma and silca rich magma erupt explosively?

silica is a rich compound consisting of silicon and oxygen and tends to be thicker and is more resistant to flow. other lava with less silica flows easily so the amount of water vapor and other gases trapped in lava influences how lava erupts.


Why silica increase in boiler drum inspite of 02ppm silca im boiler make up water?

This is due to steam seperation the silica remains in the drum water.


Is a rock with more silica in it likely to be lighter or draker than a rock with less silica in it?

A rock with more silica is likely to be lighter in weight and have a lighter color compared to a rock with less silica. Silica is a lower density mineral compared to other common rock-forming minerals, which can influence the overall density and color of the rock.


Why do continents float high relative to the ocean basin?

The continents are thicker and less dense than the materials that make up the ocean basins.


In an oil test there are silica chrome an iron?

If there has been a detection of silca, chrome and iron in your oil it could be of two things. Silica typically will be coming from your air cleaner. Chrome and iron typically come from your piston rings.


One of the most common minerals on earth?

Quartz is one of the most common minerals on Earth. It is found in a variety of environments and is known for its hexagonal crystal structure. Quartz is used in a wide range of applications, from jewelry to electronics.


How are permineralization and replacement similar?

Minerals such as silca, iron, and pyrite are critical for fossilization in both processes. However, in replacement, the hard structures of the organism dissolve and are replaced with minerals. During replacement, the original microscopic details, such as the inside of a bone, are partially or totally destroyed. ~Follow me on Twitter: @jennholguinxo I follow back!


What is an accurate description of the silicon-oxygen tetrahedron?

The silicon-oxygen tetrahedron is a building block of silicate minerals, featuring a silicon atom at the center bonded to four oxygen atoms in a tetrahedral arrangement. This arrangement forms the basic structural unit in many silicate minerals, contributing to their overall crystal structure and physical properties.


What material can be ignited by friction?

Matches are lit by friction. These work as the match heads contain sulphur and oxidising agents, with the surface of it consisting of powdered silica. As the striking surface, usually on the side of the match box, is also made up of powdered silca the glass-on-glass reaction generates heat. This causes the red phosphorous in the match head to turn into white phosphorous vapour which spontaneously combusts and starts burning the wood of the match.
