Student ideas about weathering and erosion

Abstract

This paper provides an overview and discussion of a study concerning student ideas about the terms ‘weathering’ and ‘erosion’. It describes the results of a survey conducted on 236 students, aged 16‐19, to ascertain details of their ideas about these two terms. The main factor students use to discriminate between weathering and erosion is movement. A majority of students appreciate that weathering occurs in situ, whereas erosion involves transport. Many students regard weathering as solely related to atmospheric elements, which results in some erosional and weathering processes being incorrectly classified. Human actions are perceived as types of accelerated erosion, but uncertainty surrounds whether animal activities are bio‐erosion or biological weathering. This uncertainty is also reflected in the literature. Taken collectively the results have a number of implications for teachers addressing these concepts and for the students they teach.
