This contribution develops the 7th idea out of the 10 Big Ideas that were defined within
the document Alfabetización en Ciencias de la Tierra (Pedrinaci et al., 2013). In particular,
we address the content related to the “External geological processes that transform the
Earth surface”. While developing this topic, we will also refer to guidelines 3, 4, and 9 of
the mentioned document devoted to the following topics: “Origin and transformation of
Earth materials”, “Water and air turn the Earth into a special planet”, and “Some natural
processes involve risks for humankind”. In this paper, we do not intend to furnish a detailed
description of the external geological processes. Our main goal consists in offering a clear
and structured perspective of the main concepts for their further treatment in class
