Author Profile


Summary

Through Google Earth, students will be introduced to a variety of depositional coastal forms, and then given a series of locations from which they are to answer questions relating to the shoreline feature observed. They will be require to classify each location according to Hayes' morphological classification of coasts. Strengths: Illustrates how models are developed, forces students to make interpretations from observations, to understand that observations are data, and introduces them to internet resources.
