figureThe plastic behaviour of polymers is also influenced by their morphology, or arrangement of molecules on a large scale. Stated simply, polymer morphologies are either amorphous or crystalline. Amorphous molecules are arranged randomly and are intertwined, whereas crystalline molecules are arranged closely and in a discernible order.
Mountain Plant Life. Southern California has a Mediterranean climate. This means that the weather is warm and dry in the summer, and cool and wet in the winter. The San Bernardino Mountains are well known for their lush forests of tall pine trees, but there are many other types of plants that live here. Deep-rooted chaparral covers the southern face of. the San Bernardino Mountains.
California also has 1,023 species of non-native plants, some now problematic invasive species such as yellow starthistle, that were introduced during the Spanish colonization, the California Gold Rush, and subsequent immigrations and import trading of the 18th, 19th and 20th centuries.f California's total plant population, 2,153 species, subspecies, and varieties are endemic and native to California alone, according to the 1993 Jepson Manual study. This botanical diversity stems not only from the size of the state, but also its diverse topographies, climates, and soils (e.g. serpentine outcrops).
