Richmond's Weathering A GIS Lesson
What is Weathering? The process of rocks or other substances breaking down at or near the Earth’s 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. 4 3 2 1 1. Tropical rainforest 2. Hot desert3. Temperate mountains 4. Polar Regions
Rates of Weathering. Austin, Texas Annual Temperature: 20.3oCAnnual Rainfall: 82.4cm
What kind of Weathering does the Richmond area see?take a virtual field trip and see for yourself.
Virtual Field Trip Using GIS
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.

Click on ‘GIS on the Web’
Click on ‘Applications’ andthen 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.

Weathering, Erosion & Deposition
Weathering: The natural process by which atmosphere and environmental forces, such as wind, rain, and temperature changes, disintegrate and decompose.

Weathering and Erosion
Weathering And Erosion Weathering And Erosion.
Weatheri ng Weathering is the physical and chemical breakdown of rocks at the Earth’s surface. The pieces or particles of rock (large and small) that are.
Physical (Mechanical) Weathering
As you observe the following pictures think about this… Have the landforms undergone changes? What do you think caused the changes? How long do you think.

Weathering, Erosion, & Soil
What Is Weathering? Weathering is the process that breaks down rocks into smaller and smaller pieces Weathering wears down mountains and breaks down statues.
Weathering and Erosion Weathering - processes at or near Earth’s surface that cause rocks and minerals to break down Erosion - process of removing Earth.
Weathering must happen before erosion can take place!
