Weathering and Erosion 2

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.

The process by which rock and soil are moved from one place to another is called-

• Chemical weatherin

• Erosion

• Mechanical weathering

• Deosition
