If volcanoes get their magma from the crust below them what can you say about the silica contents of Earth's crust under the ocean?
You can say that it is low in silica.
-I had this problem in my science class ^_^
What else can I help you with?
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.
How do volcanoes takes place?
Volcanoes are essentially holes in the earths surface through which magma and lava can erupt. when pressure builds up below the earths crust, magma is then forced violently out of the volcanoes.
What igneous compositions has the lowest silica content mafic ultra mafic intermediate or felsic?
Mafic igneous compositions have the lowest silica content, followed by ultramafic compositions. Mafic rocks are rich in magnesium and iron and have silica contents ranging from 45-52%. Ultramafic rocks have even lower silica content, typically below 45%.
What forces below earth surface shape landforms?
The tectonic plates below earths surface shape earths landforms
Images on volcanoes?
See the links below.
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).
What is found in the skull?
The brainstem, the contents of the neck, and below.
Where are some volcanoes found?
Most volcanoes are found around the edges of the tecktonical plates covering the earth Where these plates move apart, we might have volcanoes. Where they move together we get mountains. Certain places below the earths crust, unknown why, there are so called "Hot Spots", extreme temperature within, of which melts a hole in the plate and creates a volcano. If not mistaken, Hawaii is created due to a hot spot. Volcanoes are all over the world, even under the sea.
Which earths atmosphere is below the stratopause?
The Stratosphere
What are acceptable levels of silica in water?
The acceptable level of silica in drinking water is typically around 10 mg/L, as per EPA regulations. Silica levels below this threshold are considered safe for consumption. Excessive silica in water can lead to scaling in pipes and equipment.
What is true about plutons?
they form above earths surface (THIS ANSWER IS NOT CORRECT) They Form BELOW earths surface(:
