Fundamentally, it is the interplay between erosion and variously arranged bedrock of differing toughness that governs the lie of the land and all that stems from that (see, for example, elevation, hillside vineyard, and topography). More directly, the intensity and spatial orientation of planes of weakness in bedrock influence water and vine root penetration, and its propensity for weathering helps determine the soil depth. soil colour affects the thermal and ultraviolet radiation behaviour of soil and therefore vine performance.
