This is an undergraduate majors course in geomorphology typically taken by sophomores and juniors majoring in Earth Science or Physical Geography.

Skills and concepts that students must have mastered

Topics covered in lecture before this lab include an overview of climate and geomorphology, tectonic geomorphology, geologic time and age dating, and weathering and soils. The labs before this one include one reviewing of Earth materials and another on maps and satellite imagery with ENVI software which intrudes DTMs, LandSat images,

How the activity is situated in the course

This is a lab exercise conducted early in the semester.


Content/concepts goals for this activity

Goals for this lab include that students develop an understanding of the relationship between chemical and physical weathering and the importance of other environmental factors (e.g., temperature and pH) in chemical weathering. Students later determine the physical erosion rate of a watershed using suspended sediment data. The final activity is to use actual field data from some rapidly denuding watersheds to determine chemical and physical erosion rates.

Higher order thinking skills goals for this activity

Students conduct an experiment, analyze data they collect, calculate rates, and formulate hypotheses.
