What is the silica content of earth's crust under the oceans?
the crust
What is found in earths crust living matter oceans and atmosphere?
A the answer is hydrogen
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 measurement of the earth's crust?
The Earths crust is about 6miles thick and it covers the entire earth even at the bottom of oceans. The crust is only the beginning of the Earth and underneath is the mantle, outer layer and inner core.
What 2 layers make up the Earth's crust?
the earths crust and the rigid upper mantle
If volcanoes get their magma from the crust below them what can you say about the silica content of Earths crust under the oceans?
You can say that it is low in silica. -I had this problem in my science class ^_^
What is the silica content of earth's crust under the oceans?
the crust
What composition is earths crust?
oceanic crust is made of basalt while continental crust is made of silica rich rocks like granite.
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 element is common in earths crust and living things?
Earth's crust would be silica. Living things would be carbon.
Why the oceans floor is considered part of Earth's crust?
earths crust includes ocean floors and
What is found in earths crust living matter oceans and atmosphere?
A the answer is hydrogen
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.
On which layer of the earth would you find landforms?
The surface.

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).
