Zip. Different temperature and pressure regimes are called metamorphic facies. Emphasis is on how the appearance of land features (such as mountains, valleys, and plateaus) and sea-floor features (such as trenches, ridges, and seamounts) are a result of both constructive forces (such as volcanism, tectonic uplift, and orogeny) and destructive mechanisms (such as weathering, mass wasting, and coastal erosion). Currently, post-fire mass movement prediction has limited applications across the Mediterranean despite the abundance of both forest fires and landslide/debris flow disasters. Furthermore, this area has been interpreted as the largest upland bedrock area of the Llano Uplift and the source of siliciclastic flux to earlier Hickory Sandstone deposition (McBride et al., 2002, p. 3).
