A waterfall is a place where flowing water rapidly drops in elevation as it flows over a steep region or a cliff. Types of waterfalls include: * Block: Water descends from a relatively wide stream or river. * Cascade: Water descends a series of rock steps. * Cataract: A large, powerful waterfall. * Fan: Water spreads horizontally as it descends while remaining in contact with bedrock. * Horsetail: Descending water maintains some contact with bedrock. * Plunge: Water descends vertically, losing contact with the bedrock surface. * Punchbowl: Water descends in a constricted form and then spreads out in a wider pool. * Segmented: Distinctly separate flows of water form as it descends. * Tiered: Water drops in a series of distinct steps or falls. * Multi-step: A series of waterfalls one after another of roughly the same size each with its own sunken plunge pool. == This is a list of waterfalls in South Africa == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of waterfalls of South Africa」の詳細全文を読む スポンサード リンク
