How much does the earth's crust move per year a few mm or a few meters?
Wiki User
∙ 11y ago
A few mm (millimeters), up to a few cm (centimeters). It takes decades, or even centuries, for a tectonic plate to move a meter.
In English measurements, the largest plate movements average not much more than one or two inches a year.

What is much of earths crust made up of?
Water 75%
How much zirconium is in the earths crust?
The concentration of zirconium in the earth crust is between 150 mg/kg and 250 mg/kg.
What feature of the mantle allows movement of the earths crust occur?
The much of the mantle is solid but ductile. This allows it to convect, which aids in plate movement.
Is it true that earth's plates move a few meters per year?
Not meters, but centimeters. Current plates move at a few centimeters (hundredths of meters) per year. The largest of these movements are not much more than one or two inches.
How much is the earths crust raised when the moon is overhead?
None to speak of. The Earth's crust is fairly solid; if it was being raised and lowered like the tides, we'd record many more earthquakes than we actually see.
Which is hotter the sun or the earths crust?
The Suns surface is about 6,000K much hotter than the Earths crust. The hottest lava can get at the surface is about 1,400K
How Much Aluminum Is Found In The Earths Crust?
8.1% by weight

How much zirconium is in the earths crust?
The concentration of zirconium in the earth crust is between 150 mg/kg and 250 mg/kg.
How much of the earths surface is covered by india?
India is not covering some of the earth's crust but part of the earth's crust is part of India
How the oceanic crust move?
The earths crust layer is constantly moving because of the layer beneath it that has all the liquid magma. The magma needs a place to escape because of the pressure it takes on so where does it go, it goes up and pushes on the earths crust to escape. The places it escapes are pretty much where they follow the path of least resistance and that is where the plates of the earth crust meet. The Atlantic ridge which is the second biggest in the world has eruptions all the time constantly added to land to the sea and pushing other plates together. So in short the plates move because the layer beneath it are always on the move as well.
How much of earths crust is made up of oxygen and silcon?
47 % oxygen & 27% silicon.
Where is oxygen most commonly found in?
under the earths crust in trees and everywhere you can think of pretty much
How does the thickness of the earths crust vary?
Two main groups of crust exists: (1) oceanic and (2) continental crust. Oceanic crust is much heavier and thus much thinner (5-10 km) to be in isostatic equilibrium with the underlying mantle. Continental crust varies much more in thickness. This can be caused by collision of plates and the subsequent forming of mountains (see the Andes and Himalaya). Moreover crust can be thinned by severeal processes (e.g. dragging of subducting crust and forced extension by mantle diapeers)
What infrence did Georges Cuvier make about the earths crust?
o it is not because i am asking who he is ? Not what he does for a living? So it is not the same answer, thank u very much.
What feature of the mantle allows movement of the earths crust occur?
The much of the mantle is solid but ductile. This allows it to convect, which aids in plate movement.
What are the remaines of living thing that have been preserved in the earths crust?
Fossils, although technically they are not preserved in the earths crust; the minerals in the bones and pore spaces have been replaced by other harder minerals which take much longer to weather.There are a number of different fossilization processes. See this link :How are Fossils Formed?
