Ghost towns are made up of broken down or abandoned buildings. These towns were once inhabited, but the population has drastically decreased for various reasons, leaving behind decaying structures.
A compound cannot be broken down into different elements. This is because compounds are made of two or more different elements chemically combined in fixed ratios. An example of a compound is water (H2O), which is made of hydrogen and oxygen.
molecule
Molecules are simply atoms bonded together, so yes, they can be broken down into atoms. Such as a water molecule, which is made from two hydrgen and one oxygen, and can be broken down into those atoms.
A substance that is made of only one atom and cannot be broken down into simpler substances

the buildings where made out of bricks
because of weathering it has to be broken down
Millions of people inhabit cities and towns in the desert and each community is made up of many buildings.
A compound cannot be broken down into different elements. This is because compounds are made of two or more different elements chemically combined in fixed ratios. An example of a compound is water (H2O), which is made of hydrogen and oxygen.
Elements cannot be broken down into compounds because elements are the simplest form of matter and are made up of only one type of atom. Compounds, on the other hand, are made up of two or more different types of atoms chemically bonded together.
All of the elements of the Periodic Table cannot be broken down into simpler substances.

the buildings where made out of bricks
SNs not broken down by year. @ 25K were made from 1962-1970.

the buildings where made out of bricks
acid rain can break down buildings made from marble and other materials so over time the buildings would wear away
