Abstract
Sea level change causes horizontal shifts of the coastline (transgression and regression) that are recorded in the stratigraphic successions. These variations may be related to climate changes, such as the currently in process. Certain geological knowledge is necessary for the assimilation of these concepts by the students. The proposed activity uses fossils to recognize the sedimentary environment where rocks were formed. Fossils are also useful to infer transgression or regression trends recorded in the succession of strata. The activity is completed by a field trip in the Antromero beach (Asturias) where Cretaceous succession shows a transgressive trend upward
