A GIS Lesson
What is Weathering? The process of rocks or other substances breaking down at or near the Earths surface is called weathering.
Not to be confused with… …Erosion or Deposition.
Types of Weathering. Chemical Weathering Mechanical Weathering Biological Weathering
Mechanical Weathering. Mechanical weathering is the physical break down of a material without altering its chemical composition
Agents of Mechanical Weathering. Abrasion Exfoliation Frost Action Organic Activity Gravity
Chemical Weathering. Chemical Weathering is the alteration of the chemical composition of a material in breaking it down
Agents of Chemical Weathering. Carbonation Oxidation Acid Rain Plant Acid Hydrolysis
Rates of Weathering Tropical rainforest 2. Hot desert 3. Temperate mountains 4. Polar Regions
Rates of Weathering. Austin, Texas Annual Temperature: 20.3 o C Annual Rainfall: 82.4cm
What kind of Weathering does the Richmond area see? take a virtual field trip and see for yourself.
To visualize the images we will use a GIS software application called ArcIMS.
ArcIMS can take lots of data and images… …and tie it to a map.
These maps are georeferenced… …so you can layer them.
Go to this website: Click on Lessons on the Web
Click on GIS on the Web
Click on Applications and then click on your lesson.
Open ArcIMS up by clicking the title.
Once opened you should see this screen in your browser.
Use the worksheet to complete the virtual tour.

Rates of Weathering What is differential weathering? How does surface area affect the rate of weathering? How does climate affect the rate of weathering?
SEDIMENTARY ROCKS. Classification of Rocks 4 Rocks are aggregates of minerals. Geologists divide rocks into three groups: igneous, metamorphic, and sedimentary.
