Basic landform types refer to the various physical features found on the Earth's surface, including mountains, rivers, plains, lakes, valleys, coasts, deserts, and plateaus. Mountains can be categorized into fold mountains, fault-block mountains, volcanic mountains, and dome mountains. Rivers can be perennial, intermittent, or ephemeral, while plains can be alluvial, coastal, flood, or glacial. Lakes can be freshwater or saltwater, oligotrophic or eutrophic. Valleys can be river, glacial, rift, or hanging. Coasts can be rocky, sandy, mangrove, or coral. Deserts can be hot and dry, cold, coastal, or semi-arid. Plateaus can be intermontane, piedmont, continental, or volcanic.
