6th Gr. Science Chapter 2 Review

Bobby observed that a metal trash can was covered with rust.  What type of weathering caused the rust on the trash can?

• Mechanical weathering 
• Wind weathering
• Chemical weathering
• Erosion weathering

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:

• ice wedging
• acid rain
• permeability
• abrasion

The diagrams shows a rock with water trapped in the cracks during the day and at night. 

Which statement best explains why this process results in weathering?
