What properties of carbon explain carbon's ability to form different large and complex structures?

Yes yes yes very good

Hiya,  (the properties of carbon depends on the structure of said element.)  although, carbon is not cohesive or adhesive.carbohydrates contain carbon, hydrogen, and oxygen.  it can bond with other carbon atoms as well as other elements.a polymer is a big ole' molecule made from smaller molecules that decided to smack together and form a covalent bond. but it is fact that carbon often forms polymers.decomposition of molecules simply means the organism is clearly dead and the molecules of said dead organism can be reutilized by living organisms.hope this !

Your answer would be, the process of thermal expansion, and contraction, is one form of mechanical weathering. which is where the substance as been heated, and it expands; as the substance cools, it contracts.hope that
