Mechanical Weathering
Breaks rocks into smaller pieces by applying pressure
Freeze-thaw action
exmaple of mechanical weathering
Water seeps into rock cracks during the day
At night, water freezes and expands by 9%, widening cracks
Repeated cycles weaken the rock, causing pieces (scree) to break off
Example: Croagh Patrick, Co. Mayo
Chemical Weathering
Rocks dissolve due to chemical reactions
Carbonation
Rainwater mixes with carbon dioxide to form weak carbonic acid
This acid reacts with calcium carbonate in limestone, dissolving it
Limestone’s permeability allows rainwater to flow through
Example
The Burren, Co. Clar
