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.
Plants in this community are characterized by small, hard (sclerophyllic) evergreen (non-dropping; non-deciduous) leaves. Desert chaparral grows above California's desert cactus scrub plant community and below the pinyon-juniper woodland.ature chaparral (stands that have been allowed greater intervals between fires) is characterized by nearly impenetrable, dense thickets (except the more open chaparral of the desert). These plants are highly flammable.
