Are you talking about the diferences of a terrarium, vivarium, or paludarium to eachother? Or about the backgrounds and false bottoms created for our tank?
Im assuming the latter....
Backgrounds are typically made from expanding foam or large foam pieces that are then carved to the desired shape. Usually the biggest differences between tanks is the method used to cover up the foam. There are a ton of different ways but the most common is by using silicone, then sticking co-co fiber or peat moss to it. Another method is adding a glue, or binder, into a mix of substrate, then coating the background in the mixture. Painting, concrete, and grout are also different methods. The chosen method usually depends on what you wish the end result to look like, feel like, and how resistant to wear you want it to be.
As for the substrate sections, it depends if you are building a vivarium, or paludarium. Most vivs have false bottoms. In other words, a false bottom is a structure to "raise" the substrate above a desired water table level and to prevent it from becomming water logged. Another method of lifting the substrate is by adding a 2-4" thick layer of aquarium gravel, or lica balls. This is common practice but doesnt allow for water flow as well as having a false bottom does.
I could keep on writing but I'm not quite sure if I am on the right track that you want me to be on haha.
