No, several, not sure how many, but it's not just one.
Earths lithosphere is made up of upper mantle. The earths lithosphere is broken into separate sections and it is called as tectonic plates or plate tectonics.
One plate tectonic, or fragment, is pushed underneath another plate which causes the other one to go nowhere else but up.
Tectonic Plates float on top of the earths mantle, the earths mantle is made up liquid which is always circulating.
this is when one made up of continental crust and one made up of oceanic crust move towards eachother.
This happens because the plates under the earths crust are always moving some times the plates crash into each other, this sometimes makes one plate sink under the other one and burning up, or pushing up.
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
Plant's cell plate is made up of pectin
This happens because the plates under the earths crust are always moving some times the plates crash into each other, this sometimes makes one plate sink under the other one and burning up, or pushing up.
The core is 33% of the Earths mass
They are all caused by the Earths The Earths Tectonic PLates. e.g When there is a crack or fracture in a tectonic plate the pressure slowley builds up until it if released. This can cause tsunamis if the plate is underwater or an earthquake if it is not.
