How does freezing water cause the weathering of rocks?  The freezing water—

How do sandy beaches form?

• Waves pounding pebbles int smaller and smaller peices

• Wind eroding pebbles into smaller pieces

• Water freezing and thawing the cracks of pebbles

• Rain wearing away rocks into smaller and smaller pieces

How do plants weather rocks?

• during photosynthesis
• when roots grow into cracks of rocks and expand the rock
• when the plant moves water from the roots to the leaves
• Plants don't weather rocks

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
