They separate because of different densities.
In the diagram, layer 1 has rocks which are the oldest. Explanation. Rocks are arranged in layers that contain fossil with the oldest fossils represent at the deepest layers and the youngest fossils present near the top. Using this concept, the oldest rock layers are located at the bottom (layer1) and the youngest at the top(layer 6).

Answer:
The Lewis structure to this question can be described as follows:
Explanation:
Structure of Lewis for
:
The maximum number of electrons from valence in
is 8 (6 from S as well as 2 from negative change).
The valence electrons in the Lewis structure are placed on four sides of the atom.
Thus the structure of Lewis for
is as follows:
![\left[\begin{array}{ccc} &. .&\\: &S&:\\&. .&\end{array}\right] ^{2-}](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%20%26.%20.%26%5C%5C%3A%20%26S%26%3A%5C%5C%26.%20.%26%5Cend%7Barray%7D%5Cright%5D%20%5E%7B2-%7D)
Lewis Mg Structure:
Complete valence electrons are 2 in Mg.
The Lewis structure for Mg, therefore, is as follows:

The Lewis structure for 
The maximum valence of electrons
in is= 0.
Thus, the structure for
is as follows:

Lewis structure for P :
The maximum number of valence electrons in P is = 5.
Thus, the structure for P is=
