The central Xe atom in XeO3 has three bonding domains and one lone pair of electrons. Hence, the electron geometry is tetrahedral and molecular geometry is pyramidal.
In the north Atlantic the movement of tectonic plates(if that is what you meant by plates) is around.4 inches per year which is almost 1 cm but in the pacific area the movement is almost 2 inches which is more that four cm every year although some people say that they (in general not specific to any place in particular) travel in the range of 5-10 centimeters every year.
