Weathering & Soil

Which weathering process is most common in a hot, dry environment?

• carbonation 
• root wedging
• oxidation
• abrasion 

The diagrams  shows a natural process that weathers rock.
 Which statement best explains why this process results in weathering?

• frozen water acts as a solute
• water expands when it freezes
• the mass of water increases when it freezes
• frozen water dissolves most types of rock

A marble statue is left exposed to the weather.  Within a few years, the details on the statue have begun to weather away.  This weathering probably is caused by...

• oxygen in the air
• carbonic acid in rainwater
• lichens
• abrasion
