How do plants most commonly break large rocks into smaller pieces?

• Seeds from plants fall onto rocks and release acidic compounds.

• Plant roots grow into cracks in rocks.

• Stems of plants surround and squeeze rocks.

• Plant protects surrounding rocks from extreme temperatures.

• to keep roots from spreading

• to increase wind erosion

• to retain soil and water
