Water freezes in the cracks of rocks and then expands, breaking the rocks apart.  This is an example of ___________ weathering.

• biological
• chemical
• physical
• erosional

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

• makes the rocks last longer.
• expands cracks and breaks rocks.
• causes rocks to fall in landslides.
