The top layer of concrete is called the structural coat. It directly receives the most load which must then be transferred to lower layers.
By putting a thin layer of new concrete on top.
not normally. it depends on what you are trying to accomplish. if you need a thin layer than you can pour a thin set layer which hardens and adheres better than concrete. if the added part is thicker you can drill holes in the old and put re bar in then pour on top to help tie the two together.
No do to the concrete settling the concrete on top would split
You must form on top of the existing slab and drill in anchors to join the new concrete to the old this is called a cap

The top layer of soil where grass grows is called Humus. The next layer is the topsoil, and the layer after that is the subsoil.

Yes the crust and the top layer of the mantle is called Lithosphere.

Before the oversite concrete is laid it is usual to blind the top surface of the hardcore. The purpose of this is to prevent the wet concrete running down between the lumps of broken brick or stone, as this would make it easier for water to seep up through the hardcore and would be wasteful of concrete. To blind, or seal, the top surface of the hardcore a thin layer of very dry coarse concrete can be spread over it, or a thin layer of coarse clinker or ash can be used. This blinding layer, or coat, will be about 50 mm thick, and on it the site concrete is spread and finished with a true level top surface.
