Activity 75
Weathering, Erosion, and Deposition

American Geological Institute's Earth Science World Image Bank
To view many photographs of structures formed by erosion, go to this site maintained by the American Geological Institute and do a search for key words such as: erosion, deposition, delta or canyon for many excellent images.

The following photographs relate well to this unit:

Soil erosion on unprotected soil in a developing area.

Coffee Pot Rock, a feature formed by erosion of the Coconino Sandstone (top) and Supai Group rocks at the base.

Devils Tower at Devils Tower National Monument, Wyoming.

Delta where a river enters a lake in Alaska.

Housing development on Mississippi River Delta.

Comparing Erosion

Compare the photos from the following links either by printing each of them or by opening them in separate windows on your computer:

Photo 1 - from the Earth Science World Image Bank

Photo 2 - from the Earth Science World Image Bank

Photo 3 - a gallery of 11 photos showing erosion and weathering from National Geographic

Arrange the landforms due to erosion by size, from smallest erosion channel to largest. Which do you think might form in a very short time? Which do you think took the longest to form?
Hint: Use other objects in the picture to determine the size of the channels.

Extension

The following links can be used for the Extension:
