2. Ice wedging Freeze- thaw crack widens or gets bigger
This is mechanical
Mechanical means- is broken down external conditions

3. Wind Abrasion Sand Blasting This rock is mechanical
Mechanical means- is Broken down external conditions

4. Water Abrasion Smooth and round Water Abrasion is mechanical
Mechanical means- Broken down external conditions

5. Gravity Abrasion Cooling and breaking down, repeated impact
Gravity Abrasion is mechanical
Mechanical means- Broken down external conditions

6. Plants  Roots breaking or cracking it. Plants are mechanical
Mechanical means- Broken down external conditions

7. Animal bURROWING Animal Burrowing digging breaking it up
Animal Burrowing is mechanical
Mechanical means- Broken down external conditions

8. Acid Precipitation Burning Chemically with water.
Acid Precipitation`s is a Chemical Weathering
Chemical weathering means – Break down rock by chemical changes

9. Acid in Groundwater In groundwater chemically break down
Acid In groundwater is a Chemical weathering
Chemical weathering means – Break down rock by chemical changes

10. Acids in living things Chemical weathering inches produce.
Acids in living things is chemical weathering
Chemical weathering means – Breaking down rock by chemical changes

11. Rusting or oxidation Iron or soil rusting.
Rusting or oxidation is Chemical Weathering
Chemical weathering means – Breaking down rock by chemical changes

12. This is the end of the Mechanical and chemical weathering 
