A trough-like downbend of strata is an anticline, while an arch-like upbend is a syncline. 0000043057 00000 n Soil structure has a major influence on soil behaviour. A poorly structured soil will be much less endowed, and much less productive. A flat plate is a one- or two-way system usually supported directly on columns or load bearing walls. Some major plates include the Pacific Plate, the North American Plate, the South American Plate, the Eurasian Plate, and the African Plate.
