We study the changes induced by the effective gauge field due to ripples onthe low energy electronic structure of graphene. We show that zero energyLandau levels will form, associated to the smooth deformation of the graphenelayer, when the height corrugation, $h$, and the length of the ripple, $l$, aresuch that $h^2 / (l a) \gtrsim 1$, where $a$ is the lattice constant. Theexistence of localized levels gives rise to a large compressibility at zeroenergy, and to the enhancement of instabilities arising from electron-electroninteractions including electronic phase separation. The combined effect of theripples and an external magnetic field breaks the valley symmetry of grapheneleading to the possibility of valley selection.
