In order to describe landscapes qualitatively and quantitatively, students build 3-D sandbox models based on topographic maps and design and stage a "virtual adventure race." Sandbox landscapes are used to illustrate erosional processes, the role of water in sediment transport, relief change, and how erosion exhumes rocks from depth, while local examples are used to discuss landscapes as transient or steady over different time- and length scales.

To convince students that the observed processes act over millions of years to shape Earth's surface, quantitative dating tools are introduced.

For each dating or chronological method there is a link in the box at right to take you to that section of this page.

There, you will find a brief description of the method, plus links to take you to other webpages with more extensive information.

Similarly, in geology, if distinctive granitic pebbles can be found in the sediment beside a similar granitic body, it can be inferred that the granite, after cooling, had been uplifted and eroded and therefore was not injected into the adjacent rock sequence.

For example, beach berms, moraines, terraces, alluvial fans, landslides, lavas, fault scarps, meteorite craters, felsenmeer, and tors ranging in age from 10 terrestrial cosmogenic nuclide (TCN) dating methods.

TCN methods are used to directly determine erosion rates of landforms (boulders to mountain peaks) and landscapes (entire catchments), at timescales that are intermediate between modern stream sediment flux measurements and long-term thermochronology estimates of exhumation.
