This book presents varied geomorphological topics and planetary studies from different geomorphological regions analysed by young researchers from Latin America, from Costa Rica to southern Argentina, from the mountains to the oceans, and from the Caribbean to the Scotia tectonic plates. The six chapters included in this book originate from presentations made during the “IAG Central and South American Webinar” carried on in March 2021 for the commemoration of the “Geomorphology Week”, promoted by the International Association of Geomorphologists (IAG) and coordinated by the invited book editors. The chapters develop topics related to landforms and geomorphological processes originated by modern tectonics along a transform tectonic plate boundary, by cryo-snowy environments in the drier Central Andes, by fluvial and littoral processes in the Brazilian inland and the Atlantic coast, and by high runoff generated by storm-cells driving into mountainous and wooded terrains. New insights on Mars water features research are also included in the book. Several chapters refer to risk assessment for society or resource management considerations; other chapters refer to present or recent geomorphological processes but others do so to those developed in the Quaternary. .
