Course Description

 Geomorphology is the study of landforms and the processes that create and reshape them. The objectives of this course are to understand why landforms and landscapes look the way they do and what processes are responsible for their formation. Landscapes can be studied at different scales, so we will look at processes that impact large continental-scale areas such as mountain building due to plate tectonics, as well as much more local and regional-scale processes such as mass wasting events on hill slopes. Landforms evolve in response to a combination of natural and anthropogenic processes and every landscape is a representation of its history.

 Assignments

There will be three to five relatively short practical exercises assigned throughout the course. They will include activities such as map and/or air photo, or using Google Earth to measure, quantify, and describe various landforms and/or landscapes discussed in class.

Presentations

 Each student will be required to give a 10-minute annotated poster presentation on a topic of their choice (approved by the instructor) or a topic selected from the list provided below. A topic sign-up sheet will be posted. There will be no duplication, however, it may be possible for students to work in groups of two.

 Microsoft Teams

In addition to the course website, I will use Microsoft Teams to manage the course. This includes distributing lecture notes prior to class, posting and receiving assignments, giving tests, and responding to questions outside of class time.  I will provide you with an access code and instructions on how to join our Geomorphology Team via your BU email prior to the first class.
