Plants are a great force that impacts the landscapes we see in our daily lives.
Have you ever seen moss creeping over bricks or walked over a tree root bursting through the sidewalk? If you have, you have witnessed plant-driven weathering. Plant-driven weathering refers to production of chemicals, which aid in the break down of rocks. Larger plants, such as trees can cause cracking or breaking of rocks. Plants can also protect rocks from weathering. Roots are a great stabilizer for soil. They prevent slides of rocks or mud on hills, cliff sides, and other slopes. Plants also have the ability to shield rocks from other weathering forces, such as water.
