How does the silica content of earths crust under the oceans get magma?
Silica-rich magma forms in mid-ocean ridges due to partial melting of the upper mantle, as a result of increased temperature and decreased pressure. This magma rises through cracks in the oceanic crust and can eventually erupt at the surface as lava.
How do you get silicon out of earths crust?
Silicon is typically extracted from silica, which is found in the Earth's crust as quartz. The most common method to extract silicon involves heating silica with carbon in an electric arc furnace to produce silicon and carbon monoxide gas. This process is known as the carbothermic reduction of silica.
What type of plate boundary would have less silica content?
A divergent plate boundary would have less silica content compared to a convergent plate boundary. Divergent boundaries involve the separation of tectonic plates, with new oceanic crust forming from magma that is relatively low in silica content. In contrast, convergent boundaries involve the collision of tectonic plates, resulting in the melting of crust with higher silica content, leading to more explosive volcanic activity.
Why does Silica content in most magmas range from 45 to almost 80 percent by weight?
Silicon is one of the most abundant elements in the crust and mantle. Since all magmas are derived from the crust or mantle, the silica content will be significant, and dependent on its source for its constituent percentage.
What is the outer layer of the earth called?
The crust is the outer or surface layer of the planet.
If volcanoes get their magma from the crust below them what can you say about the silica content of Earths crust under the oceans?
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.

What composition is earths crust?
oceanic crust is made of basalt while continental crust is made of silica rich rocks like granite.
Why the oceans floor is considered part of Earth's crust?
earths crust includes ocean floors and
Why is there less silica in ocean water than river and ground water?
almost no silica in ocean water but most of its the earths crust.
What do scientists believe that is happening to the segments of earths crust?
it has been washed into the oceans as the continental crust has eroded.
In earths crust What type of rock is found under the oceans?
Oceanic crust, new oceanic crust is produced by seafloor spreading.

A divergent plate boundary would have less silica content compared to a convergent plate boundary.

Does the earths crust extend deeper below the continents or below the ocean basins?
Earths crust extend deeper below the continents than below the oceans basins (or at least this is what I think).

The short periods contain some of the most common elements found in?
earths crust , oceans and atmosphere
