Weathering & Erosion

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.

Sediments being carried down stream by water or being carried away by wind are examples of

• weathering
• erosion
• deposition

A statue being broken down by reacting with acid rain is an example of

• mechanical weathering
• chemical weathering
• erosion
• deposition
