Let G be a minor-closed class of graphs all whose forbidden minors are 2-connected. We prove a zero-one law in monadic second-order logic for random connected graphs in G, and a convergence law for all graphs in G. For each surface S, we prove a zero-one law in first order logic for random connected graphs embeddable in S, and a convergence law for all graphs embeddable in S.
The proofs are based on several properties that hold for almost all graphs in a minor-closed class.
