how many layers of plates are there underground?

Answer 1

I assume you are referring the the tectonic plates one which form the crust of the Earth - which we live.

There is 1 layer. It is broken into about nine large plates and a number of smaller plates we call the tectonic plates. These are comprised primarily of cool, solid rock 4 to 40 miles thick, these enormous blocks of Earth’s crust vary in size and shape, and have definite borders that cut through continents and oceans alike. When the collide - well, you know what happens...

Answer 2

I'm not sure that you'd describe them as plates really. You have the Continental crust which is thick and the least dense, then the oceanic crust which is denser and thinner.

Under the crust layer you have the fluid Mantle but this is thousands of miles thick followed by the liquid outer core and solid inner core.

Answer 3

There are 12 main plates on the earth and they are only layered when they collide. Are you sure you meant to say plates?

Answer 4

it extremely is by way of composition of the magma below the sea is wealthy in silica and magnesium which while react variety a basalt ..... Sima is the call for the decrease layer of the Earth's crust. this deposit is made up of rocks wealthy in silicates and magnesium minerals. in many situations the sima while it contains the exterior is basalt, so each and every so often this deposit is named the 'basalt layer' of the crust. The sima layer is that's called the 'basal crust' or 'basal layer' by way of fact it extremely is the backside layer of the crust. by way of fact the sea flooring are especially sima, it is likewise oftentimes stated by way of fact the 'oceanic crust'. The call 'sima' replaced into taken from the 1st 2 letters of silica and of magnesium. comparable is the call 'Sial' that's the call for the better layer of the Earth's crust. while at continental crust the composition is wealthy in aluminium and silica..... Sial or SiAl is the call for the better layer of the Earth's crust, that's additionally properly-known by way of fact the continental crust by way of fact it extremely is absent interior the huge oceanic basins. this deposit is made up of rocks wealthy in silicates and aluminium minerals. while the sial contains the exterior it extremely is typically granitic, so each and every so often this deposit is named the 'granitic layer' of the crust. American geologists oftentimes examine with the rocks in this deposit as felsic. on the continental plates the sial runs between 5 km and 70 km deep. by way of fact in a real experience the sial floats on the sima, mountains improve down besides as up, very resembling icebergs on the sea, as a result the large version in intensity. See Isostasy. The call 'sial' replaced into taken from the 1st 2 letters of silica and of aluminium. comparable is the call 'sima' that's the call for the decrease layer of the Earth's crust, that's uncovered interior the sea basins sial is a lighter layer than that of sima layer for this reason that continent is above oceans
