Examples

• The weatherings of the limestone cliffs created dramatic formations over millions of years.
• Chemical weatherings occur when minerals in rocks react with water and acids.
• The building’s weatherings help direct rainwater away from the foundation.
• Freeze-thaw weatherings are common in mountainous regions.
• The architect designed proper weatherings to prevent water damage.
• Physical weatherings break rocks apart without changing their chemical composition.
