mechanical weathering
acid rain
oxidation
The surfaces of old concrete statues are often covered with small holes or pits. Which of these MOST LIKELY causes these holes or pits?
The concrete becomes pitted as water freezes in small cracks in the statue.
The concrete is chemically weathered by acid rain.
The concrete is chipped away by sand particles blown by strong winds
Long exposure to sunlight causes the pits to form.
The diagrams shows a rock with water trapped in the cracks during the day and at night.

frozen water dissolves most types of rock
